ALKALINE XYLOGLUCANASE

Abstract: A xyloglucanase having a relative xyloglucanase activity of atleast 50% at pH7 and either no or an insignificant cellulolytic activity is obtainable e.g. from a strain of Bacillus. A xyloglucanase comprising an amino acid sequence as shown in positions 30-261 of SEQ ID NO:2 or homologues may be derived from e.g. Bacillus licheniformis, ATCC 14580, and may be encoded by polynucleotide molecules comprising a nucleotide sequence as shown in SEQ ID NO:1 from nucleotide 88 to nucleotide 783; and a xyloglucanase comprising an amino acid sequence as shown in positions 1-537 of SEQ ID NO:4 or homologues may be derived from e.g. B. agaradhaerens, NCIMB 40482, and may be encoded by polynucleotide molecules comprising a nucleotide sequence as shown in SEQ ID NO:3 from nucleotide 1 to nucleotide 1611. The xyloglucanases are useful e.g. in cleaning compositions and for treatment of cellulosic fibres.

Description: ALKALINE XYLOGLUCANASE The present invention relates to alkaline xyloglucanases, i.e. enzymes exhibiting xyloglucanase activity as their major enzymatic activity in the neutral and alkaline pH ranges; to a method of producing such enzymes; and to methods for using such enzymes in the textile, detergent and cellulose fiber processing industries. BACKGROUND OF THE INVENTION Xyloglucan is a major structural polysaccharide in the primary (growing) cell wall of plants. Structurally, xyloglucans consists of a cellulose-like beta-1, 4-linked glucose backbone which is frequently substituted with various side chains. The xyloglucans of most dicotyledonous plants, some monocotyledons and gymnosperms are highly branched polysaccharides in which approx. 75% of the glucose residues in the backbone bear a glycosyl side chain at 0-6. The glycosyl residue that is directly attached to the branched glucose residue is invariably alfa-D-xylose. Up to 50% of the side chains in the xyloglucans contain more than one residue due to the presence of beta-D- galactose or alfa-L-fucose-( 1-2) -beta-D-galactose moieties at O- 2 of the xylose residues (C. Ohsumi and T. Hayashi (1994) Plant and Cell Physiology 35:963-967; G. J. McDougall and S. C. Fry (1994) Journal of Plant Physiology 143:591-595; J. L. Acebes et al. (1993) Phytochemistry 33:1343-1345). On acid hydrolysis, the xyloglucan extracted from cotton fibers yielded glucose, xylose, galactose and fucose in the ratio of 50:29:12:7 (Hayashi et al., 1988) . Xyloglucans produced by solanaceous plants are unusual in that typical only 40% of the beta-1, 4-linked glucose residues bear a glycosyl side chain at 0-6. Furthermore, up to 60% of the xylose residues are substituted at 0-2 with alfa-L-arabinose residues and some solanaceous plants, such as potato, also have xyloglucans with beta-D-galactose substituents at 0-2 of some of the xylose residues (York et al (1996)). Xyloglucan is believed to function in the primary wall of plants by crosslinking cellulose-microfibrils, forming a cellulose-xyloglucan network. This network is considered necessary for the structural integrity of primary cell-walls (Carpita et al. , 1993). Another important function of xyloglucan is to act as a repository for xyloglucan subunit oligo- saccharides that are physiologically active regulators of plant cell growth. Xyloglucan subunits may also modulate the action of a xyloglucan endotransglycosylase (XET) , a cell-wall associated enzyme that has been hypothesized to play a role in the elongation of plant cell walls. Therefore xyloglucan might play an important role in wall loosening and consequently cell expansion (Fry et al. , 1992). The seeds of many dicotyledonous species contain xyloglucan as the major polysaccharide storage reserve. This type of xyloglucan, which is localized in massive thickenings on the inside of the seed cotyledon cell wall, is composed mainly of glucose, xylose and galactose (Rose et al., 1996). Seeds of the tamarind tree Tamarindus indica became a commercial source of gum in 1943 when the gum was found useful as a paper and textile size. Sizing of jute and cotton with tamarind xyloglucan has been extensively practiced in Asia owing to the low cost of the gum and to its excellent properties. Food applications of tamarind xyloglucan include use in confections, jams and jellies and as a stabilizer in ice cream and mayonnaise (Whistler et al., 1993). Xyloglucanase activity is not included in the classification of enzymes provided by the Enzyme Nomenclature (1992) . Hitherto, this enzymatic activity has simply been classified as glucanase activity and has often been believed to be identical to cellulolytic activity (EC 3.2.1.4), i.e. activity against β-l,4-glycosidic linkages in cellulose or cellulose derivative substrates, or at least to be a side activity in enzymes having cellulolytic activity. However, a true xyloglucanase is a true xyloglucan specific enzyme capable of catalyzing the solubilisation of xyloglucan to xyloglucan oligosaccharides but which does not exhibit substantial cellulolytic activity, e.g. activity against the conventionally used cellulose-like substrates CMC (carboxymethylcellulose) , HE cellulose and Avicel (microcrystalline cellulose) . A xyloglucanase cleaves the beta-1 , -glycosidic linkages in the backbone of xyloglucan. Xyloglucanase activity is described by Vincken et al. (1997) who characterizes three different endoglucanases from Tric o erjna viride (similar to T. reesei ) which all have high activity against cellulose or CMC and show that the Endol (which 5 is indeed belonging to family 5 of glycosyl hydrolases, see Henrissat, B. et al. (1991, 1993)) has essentially no (i.e. very little) activity against xyloglucan, and that EndoV (belonging to the family 7 of glycosyl hydrolases) and EndoIV (belonging to the family 12 of glycosyl hydrolases) both have activity against 10 xyloglucan and CMC, respectively, of the same order of magnitude. International patent publication WO 97/13862 describes two cellulases from Aspergillus niger strain N400 as described in EP-A 0 463 706. The sequence of lacl2 can be ascribed to family 15 12 , and the sequence of lac64 is determined as belonging to family 5 by comparison with known homologous cellulases in the EMBL data base. Both enzyme have cellulase and β-glucanase activity. They have the highest activity against barley β- glucan, and they both show good CMC activity and some 20 xyloglucanase activity. Both enzyme has pH optima at 3.5 on CMC and 5.5 on barley β-glucan. International Patent Publication WO 94/14953 discloses a xyloglucanase (EG II) cloned from the fungus Aspergillus aculeatus and expressed in the fungus Aspergillus oryzae which 25 has high xyloglucanase activity and very little cellulase activity. This EG II enzyme which shows xyloglucanase activity in the pH range 2.5-6 and optimum activity at pH 3-4 also belongs to family 12 of glycosyl hydrolases. In summary, up till now xyloglucanase activity has only 30 been found in fungal enzymes belonging to the families 7 and 12 of glycosyl hydrolases and exhibiting this activity in the acidic to near neutral pH range. However, many important processes, either industrial or using industrially produced agents, are operating at an alkaline 35 pH. Thus, it is an object of the present invention to provide a true xyloglucanase enzyme with a high xyloglucanase activity at an alkaline pH and essentially no activity on cellulose or cellulose derivatives. SUMMARY OF THE INVENTION The inventors have now found enzymes having substantial xyloglucanase activity in the alkaline range, such enzymes having either no or an insignificant cellulolytic activity. Accordingly, the present invention relates to an enzyme preparation comprising a xyloglucanase having a relative xyloglucanase activity of at least 50% at pH 7 or a pH above 7, and preferably a minor or no activity on cellulose or cellulose derivative substrates, e.g. having a ratio of maximum xyloglucanase activity to maximum activity on CMC or Avicel of at least 2:1. The inventors have also succeeded in cloning and expressing a xyloglucanase, ie the invention relates in further aspects to a xyloglucanase which is (a) a polypeptide produced by Bacillus agaradhaerens , N CIMB 40482, or (b) a polypeptide comprising an amino acid sequence as shown in positions 1-537 SEQ ID NO: 4, or (c) an analogue of the polypeptide defined in (a) or (b) which is at least 70% homologous with said polypeptide, or is derived from said polypeptide by substitution, deletion or addition of one or several amino acids, or is immunologically reactive with a polyclonal antibody raised against said polypeptide in purified form; and to a xyloglucanase which is (a) a polypeptide produced by Bacillus licheniformis , ATCC 14580, or (b) a polypeptide comprising an amino acid sequence as shown in positions 30-261 of SEQ ID NO: 2, or (c) an analogue of the polypeptide defined in (a) or (b) which is at least 70% homologous with said polypeptide, or is derived from said polypeptide by substitution, deletion or addition of one or several amino acids, or is immunologically reactive with a polyclonal antibody raised against said polypeptide in purified form; and to an isolated polynucleotide molecule encoding a polypeptide having xyloglucanase activity selected from (a) polynucleotide molecules comprising a nucleotide sequence as shown in SEQ ID N0:1 from nucleotide 88 to nucleotide 783; (b) polynucleotide molecules that encode a polypeptide that is at least 70% identical to the amino acid sequence of SEQ ID NO: 2 from amino acid residue 30 to amino acid residue 261; and (c) degenerate nucleotide sequences of (a) or (b) ; and to an isolated polynucleotide molecule encoding a polypeptide having xyloglucanase activity selected from the group consisting of: (a) polynucleotide molecules comprising a nucleotide sequence as shown in SEQ ID NO: 3 from nucleotide 1 to nucleotide 1611; (b) polynucleotide molecules that encode a polypeptide that is at least 70% identical to the amino acid sequence of SEQ ID NO: 4 from amino acid residue 1 to amino acid residue 537; and (c) degenerate nucleotide sequences of (a) or (b) . In further aspects, the invention provides an expression vector comprising a DNA segment which is eg a polynucleotide molecule of the invention; a cell comprising the DNA segment or the expression vector; and a method of producing an enzyme exhibiting xyoglucanase activity, which method comprises culturing the cell under conditions permitting the production of the enzyme, and recovering the enzyme from the culture. In yet another aspect the invention provides an isolated enzyme exhibiting xyloglucanase activity, characterized in (i) being free from homologous impurities and (ii) the enzyme is produced by the method described above. The novel enzyme of the present invention is useful for the treatment of cellulosic material, especially cellulose- containing fiber, yarn, woven or non-woven fabric. The treatment can be carried out during the processing of cellulosic material into a material ready for garment manufacture or fabric manufacture, e.g. in the desizing or scouring step; or during industrial or household laundering of such fabric or garment. Accordingly, in further aspects the present invention relates to a detergent composition comprising an enzyme having substantial xyloglucanase activity in the alkaline range; and to use of the enzyme of the invention for the treatment of cellulose-containing fibers, yarn, woven or non-woven fabric. The present invention has now made it possible to use a truly enzymatic scouring process in the preparation of cellulosic material e.g. for proper response in subsequent dyeing operations. Further, it is contemplated that detergent compositions comprising the novel enzyme are capable of removing or bleaching certain soils or stains present on laundry, especially soils and spots resulting from xyloglucan-containing food, plants, and the like. It is also contemplated that treatment with detergent compositions comprising the novel enzyme can prevent binding of certain soils to the xyloglucan left on the cellulosic material. DETAILED DESCRIPTION OF THE INVENTION Cellulases are found in more than 10 different families of glycosyl hydrolases. Some of the cellulases also exhibit xyloglucanase activity. Today, such cellulases have been found among those classified in the families 5, 7 and 12. The substrate specificity is, however, not directly correlated with the family: within a family the main enzymatic activity can be cellulase or mannanase (family 5), or lichinase, β-1, 3-glucanase or xyloglucantransferase activity (family 16) . The only enzyme hitherto disclosed as having activity against xyloglucan as the major or main enzymatic activity is the Aspergillus aculeatus EG II disclosed in WO 94/14953. As mentioned above, this activity has not yet an entry in the official Enzyme Nomenclature. In the present context, the term "enzyme preparation" is intended to mean either be a conventional enzymatic fermentation product, possibly isolated and purified, from a single species of a microorganism, such preparation usually comprising a number of different enzymatic activities; or a mixture of monocomponent enzymes, preferably enzymes derived from bacterial or fungal species by using conventional recombinant techniques, which enzymes have been fermented and possibly isolated and purified separately and which may originate from different species, preferably fungal or bacterial species; or the fermentation product of a microorganism which acts as a host cell for expression of a recombinant xyloglucanase, but which microorganism simultaneously produces other enzymes, e.g. xyloglucanases, proteases, or cellulases, being naturally occurring fermentation products of the microorganism, i.e. the enzyme complex conventionally produced by the corresponding naturally occurring microorganism. In a preferred embodiment, the xyloglucanase has a relative activity at pH 7 of at least 50%, preferably at least 75%, more preferably at least 80%, especially at least 90%, compared to the activity at the optimal pH. In another preferred embodiment, the xyloglucanase has a relative activity at pH 8 of at least 50%, preferably at least 60%, more preferably at least 75%, especially at least 90%, compared to the activity at the optimal pH. In yet another preferred embodiment, the xyloglucanase has a relative activity at pH 9 of at least 10%, preferably at least 20%, more preferably at least 25%, compared to the activity at the optimal pH. In yet another preferred embodiment, the xyloglucanase has a relative activity at pH 9.5 of at least 5%, preferably at least 10%, more preferably at least 15%, compared to the activity at the optimal pH. In yet another preferred embodiment, the xyloglucanase has a relative activity at pH 10 of at least 5%, compared to the activity at the optimal pH. In another preferred embodiment the xyloglucanase has a relative activity at a temperature of 50°C, preferably of at least 60%, preferably at least 70%, compared to the activity at the optimal temperature. In yet another preferred embodiment, at a temperature of 60°C, the relative xyloglucanase activity is at least 40%, preferably at least 50%; at a temperature of 70°C, the relative xyloglucanase activity is at least 40%, preferably at least 45%, especially at least 50%. In a preferred embodiment, the xyloglucanase has a minor or no activity on cellulose or cellulose derivative substrates. A conventional substrate for determining cellulase activity (endo- β-1, 4-glucanase activity, jf. EC 3.2.1.4) is carboxymethylcellulose (CMC) . Another conventional substrate for determining cellulase or cellobiohydrolase activity (EC 3.2.1.91) is Avicel which is a micro-crystalline cellulose well known by the person skilled in the art. Preferably, the ratio of maximum xyloglucanase activity to maximum activity on either CMC or Avicel is at least 2:1, more preferably at least 3:1, more preferably at least 4:1, even more preferably at least 5:1, even more preferably at least 8:1, especially at least 10:1. The xyloglucanase preparation of the invention may further comprise one or more enzymes selected from the group consisting of proteases, cellulases (endo-β-1, 4-glucanases) , β-glucanases (endo-β-1, 3 (4) -glucanases) , lipases, cutinases, peroxidases, laccases, amylases, glucoamylases, pectinases, reductases, oxidases, phenoloxidases, ligninases, pullulanases, arabinanases, hemicellulases, mannanases, galactanases, xylanases, pectin acetyl esterases, rhamnogalacturonan acetyl esterases, polygalacturonases, rhamnogalacturonases, pectin lyases, pectate lyases, pectin methylesterases, cellobiohydrolases, transglutaminases; or mixtures thereof. In a preferred embodiment, one or more or all enzymes in the preparation is produced by using recombinant techniques, i.e. the enzyme (s) is/are mono-component enzyme (s) which is/are mixed with the other enzyme (s) to form an enzyme preparation with the desired enzyme blend. In another aspect, the present invention also relates to a method of producing the enzyme preparation of the invention, the method comprising culturing a microorganism capable of producing the xyloglucanase under conditions permitting the production of the enzyme, and recovering the enzyme from the culture. Culturing may be carried out using conventional fermentation techniques, e.g. culturing in shake flasks or fermentors with agitation to ensure sufficient aeration on a growth medium inducing production of the xyloglucanase enzyme. The growth medium may contain a conventional N-source such as peptone, yeast extract or casamino acids, a reduced amount of a conventional C-source such as dextrose or sucrose, and an inducer such as xyloglucan or composit plant substrates such as cereal brans (e.g. wheat bran or rice husk) . The recovery may be carried out using conventional techniques, e.g. separation of bio-mass and supernatant by centrifugation or filtration, recovery of the supernatant or disruption of cells if the enzyme of interest is intracelluiar, perhaps followed by further purification as described in EP 0 406 314 or by crystallization as described in WO 97/15660. In the present context the term "expression vector" denotes a DNA molecule, linear or circular, that comprises a segment encoding a polypeptide of interest operably linked to additional segments that provide for its transcription. Such additional segments may include promoter and terminator sequences, and may optionally include one or more origins of replication, one or more selectable markers, an enhancer, a polyadenylation signal, and the like. Expression vectors are generally derived from plasmid or viral DNA, or may contain elements of both. The expression vector of the invention may be any expression vector that is conveniently subjected to recombinant DNA procedures, and the choice of vector will often depend on the host cell into which the vector is to be introduced. Thus, the vector may be an autonomously replicating vector, i.e. a vector which exists as an extrachromosomal entity, the replication of which is independent of chromosomal replication, e.g. a plasmid. Alternatively, the vector may be one which, when introduced into a host cell, is integrated into the host cell genome and replicated together with the chromosome (s) into which it has been integrated. The term "recombinant expressed" or "recombinantly expressed" used herein in connection with expression of a polypeptide or protein is defined according to the standard definition in the art. Recombinantly expression of a protein is generally performed by using an expression vector as described immediately above. The term "isolated", when applied to a polynucleotide molecule, denotes that the polynucleotide has been removed from its natural genetic milieu and is thus free of other extraneous or unwanted coding sequences, and is in a form suitable for use within genetically engineered protein production systems. Such isolated molecules are those that are separated from their natural environment and include cDNA and genomic clones. Isolated DNA molecules of the present invention are free of other genes with which they are ordinarily associated, but may include naturally occurring 5 1 and 3' untranslated regions such as promoters and terminators. The identification of associated regions will be evident to one of ordinary skill in the art (see for example, Dynan and Tijan, Nature 316:774-78, 1985). The term "an isolated polynucleotide" may alternatively be termed "a cloned polynucleotide" . When applied to a protein/polypeptide, the term "isolated" indicates that the protein is found in a condition other than its native environment. In a preferred form, the isolated protein is substantially free of other proteins, particularly other homologous proteins (i.e. "homologous impurities" (see below) ) . It is preferred to provide the protein in a greater than 40% pure form, more preferably greater than 60% pure form. Even more preferably it is preferred to provide the protein in a highly purified form, i.e., greater than 80% pure, more preferably greater than 95% pure, and even more preferably greater than 99% pure, as determined by SDS-PAGE. The term "isolated protein/polypeptide may alternatively be termed "purified protein/polypeptide" . The term "homologous impurities" means any impurity (e.g. another polypeptide than the polypeptide of the invention) which originate from the homologous cell where the polypeptide of the invention is originally obtained from. The term "obtained from" as used herein in connection with a specific microbial source, means that the polynucleotide and/or polypeptide produced by the specific source, or by a cell in which a gene from the source have been inserted. The term "operably linked", when referring to DNA segments, denotes that the segments are arranged so that they function in concert for their intended purposes, e.g. transcription initiates in the promoter and proceeds through the coding segment to the terminator The term "polynucleotide" denotes a single- or double- stranded polymer of deoxyribonucleotide or ribonucleotide bases read from the 5 1 to the 3 1 end. Polynucleotides include RNA and DNA, and may be isolated from natural sources, synthesized in vitro , or prepared from a combination of natural and synthetic molecules. The term "complements of polynucleotide molecules" denotes polynucleotide molecules having a complementary base sequence and reverse orientation as compared to a reference sequence. For example, the sequence 5' ATGCACGGG 3' is complementary to 5' CCCGTGCAT 3 • . The term "degenerate nucleotide sequence" denotes a sequence of nucleotides that includes one or more degenerate codons (as compared to a reference polynucleotide molecule that encodes a polypeptide) . Degenerate codons contain different triplets of nucleotides, but encode the same amino acid residue (i.e., GAU and GAC triplets each encode Asp) . The term "promoter" denotes a portion of a gene containing DNA sequences that provide for the binding of RNA polymerase and initiation of transcription. Promoter sequences are commonly, but not always, found in the 5' non-coding regions of genes. 5 The term "secretory signal sequence" denotes a DNA sequence that encodes a polypeptide (a "secretory peptide") that, as a component of a larger polypeptide, directs the larger polypeptide through a secretory pathway of a cell in which it is synthesized. The larger peptide is commonly cleaved to remove 0 the secretory peptide during transit through the secretory pathway. POLYNUCLEOTIDES : Within preferred embodiments of the invention an isolated 5 polynucleotide of the invention will hybridize to similar sized regions of SEQ ID N0:1 or SEQ ID NO: , or a sequence complementary thereto, under at least medium stringency conditions . In particular polynucleotides of the invention will 0 hybridize to a denatured double-stranded DNA probe comprising either the full sequence shown in SEQ ID NO: 3 or the full sequence shown in positions 88-783 of SEQ ID NO:l or any probe comprising a subsequence of SEQ ID NO: 3 or SEQ ID NO:l having a length of at least about 100 base pairs under at least medium 5 stringency conditions, but preferably at high stringency conditions as described in detail below. Suitable experimental conditions for determining hybridization at medium, or high stringency between a nucleotide probe and a homologous DNA or RNA sequence involves presoaking of the filter containing the 30 DNA fragments or RNA to hybridize in 5 x SSC (Sodium chloride/Sodium citrate, Sambrook et al. 1989) for 10 min, and prehybridization of the filter in a solution of 5 x SSC, 5 x Denhardt's solution (Sambrook et al. 1989), 0.5 % SDS and 100 μg/ml of denatured sonicated salmon sperm DNA (Sambrook et al. 35 1989) , followed by hybridization in the same solution containing a concentration of lOng/ml of a random-primed (Feinberg, A. P. and Vogelstein, B. (1983) Anal. Biochem. 132:6-13), 32P-dCTP- labeled (specific activity higher than 1 x 109 cpm/μg ) probe for 12 hours at ca. 45°C. The filter is then washed twice for 30 minutes in 2 x SSC, 0.5 % SDS at least 60°C (medium stringency), still more preferably at least 65 °C (medium/high stringency) , even more preferably at least 70 °C (high stringency) , and even more preferably at least 75 °C (very high stringency) . Molecules to which the oligonucleotide probe hybridizes under these conditions are detected using a x-ray film. As previously noted, the isolated polynucleotides of the present invention include DNA and RNA. Methods for isolating DNA and RNA are well known in the art. DNA and RNA encoding genes of interest can be cloned in Gene Banks or DNA libraries by means of methods known in the art. Polynucleotides encoding polypeptides having endogucanase activity of the invention are then identified and isolated by, for example, hybridization or PCR. The present invention further provides counterpart polypeptides and polynucleotides from different bacterial strains (orthologs or paralogs) . Of particular interest are xyloglucanase polypeptides from gram-positive alkalophilic strains, including species of Bacillus . Species homologues of a polypeptide with xyloglucanase activity of the invention can be cloned using information and compositions provided by the present invention in combination with conventional cloning techniques. For example, a DNA sequence of the present invention can be cloned using chromosomal DNA obtained from a cell type that expresses the protein. Suitable sources of DNA can be identified by probing Northern blots with probes designed from the sequences disclosed herein. A library is then prepared from chromosomal DNA of a positive cell line. A DNA sequence of the invention encoding an polypeptide having xyloglucanase activity can then be isolated by a variety of methods, such as by probing with probes designed from the sequences disclosed in the present specification and claims or with one or more sets of degenerate probes based on the disclosed sequences. A DNA sequence of the invention can also be cloned using the polymerase chain reaction, or PCR (Mullis, U.S. Patent 4,683,202), using primers designed from the sequences disclosed herein. Within an additional method, the DNA library can be used to transform or transfect host cells, and expression of the DNA of interest can be detected with an antibody (monoclonal or polyclonal) raised against the xylooglucanase cloned from B . licheniformis, ATCC 14580, or from B . agaradhaerenε , NCIMB 40482, expressed and purified as described in Materials and Methods and Examples 5, 6 and 7 , or by an activity test relating to a polypeptide having xyloglucanase activity. POLYPEPTIDES: The sequence of SEQ ID NO:4 and of amino acids nos. 30-261 of SEQ ID NO: 2, respectively, is a mature xyloglucanase sequence of the catalytic active domain. The present invention also provides xyloglucanase polypeptides that are substantially homologous to the polypeptide of SEQ ID NO: 2 or SEQ ID NO: 4 and species homologs (paralogs or orthologs) thereof. The term "substantially homologous" is used herein to denote polypeptides having 75%, preferably at least 80%, more preferably at least 85%, and even more preferably at least 90%, sequence identity to the sequence shown in SEQ ID NO: 4 or in amino acids nos. 30-261 of SEQ ID NO: 2 or their orthologs or paralogs. Such polypeptides will more preferably be at least 95% identical, and most preferably 98% or more identical to the sequence shown in SEQ ID NO: 4 or in amino acids nos. 226-490 of SEQ ID NO: 2 or its orthologs or paralogs. Percent sequence identity is determined by conventional methods , by means of computer programs known in the art such as GAP provided in the GCG program package (Program Manual for the Wisconsin Package, Version 8, August 1994, Genetics Computer Group, 575 Science Drive, Madison, Wisconsin, USA 53711) as disclosed in Needleman, S.B. and Wunsch, CD., (1970), Journal of Molecular Biology, 48, 443-453, which is hereby incorporated by reference in its entirety. GAP is used with the following settings for polypeptide sequence comparison: GAP creation penalty of 3.0 and GAP extension penalty of 0.1. Sequence identity of polynucleotide molecules is determined by similar methods using GAP with the following settings for DNA sequence comparison: GAP creation penalty of 5.0 and GAP extension penalty of 0.3. Substantially homologous proteins and polypeptides are characterized as having one or more amino acid substitutions, deletions or additions. These changes are preferably of a minor nature, that is conservative amino acid substitutions (see Table 2) and other substitutions that do not significantly affect the folding or activity of the protein or polypeptide; small deletions, typically of one to about 30 amino acids; and small amino- or carboxyl-terminal extensions, such as an amino- terminal methionine residue, a small linker peptide of up to about 20-25 residues, or a small extension that facilitates purification (an af inity tag) , such as a poly-histidine tract, protein A (Nilsson et al. , EMBO J. 4.: 1075, 1985; Nilsson et al. , Methods Enzymol. 198:3. 1991. See, in general Ford et al. , Protein Expression and Purification 2.: 95-107, 1991, which is incorporated herein by reference. DNAs encoding affinity tags are available from commercial suppliers (e.g., Pharmacia Biotech, Piscataway, NJ; New England Biolabs, Beverly, MA) . However, even though the changes described above preferably are of a minor nature, such changes may also be of a larger nature such as fusion of larger polypeptides of up to 300 amino acids or more both as amino- or carboxyl-terminal extensions to a polypeptide of the invention having xyloglucanase activity. Table 1 Conservative amino acid substitutions Basic: arginine lysine histidine Acidic: glutamic acid aspartic acid Polar: glutamine asparagine Hydrophobic: leucine isoleucine valine Aromatic: phenylalanine tryptophan tyrosine Small: glycine alanine serine threonine methionine In addition to the 20 standard amino acids, non-standard amino acids (such as 4-hydroxyproline, 6-N-methyl lysine, 2- aminoisobutyric acid, isovaline and a-methyl serine) may be substituted for amino acid residues of a polypeptide according to the invention. A limited number of non-conservative amino acids, amino acids that are not encoded by the genetic code, and unnatural amino acids may be substituted for amino acid residues. "Unnatural amino acids" have been modified after protein synthesis, and/or have a chemical structure in their side chain (s) different from that of the standard amino acids. Unnatural amino acids can be chemically synthesized, or preferably, are commercially available, and include pipecolic acid, thiazolidine carboxylic acid, dehydroproline, 3- and 4- ethylproline, and 3 , 3-dimethylproline. Essential amino acids in the xyloglucanase polypeptides of the present invention can be identified according to procedures known in the art, such as site-directed mutagenesis or alanine- scanning mutagenesis (Cunningham and Wells, Science 244 : 1081- 1085, 1989). In the latter technique, single alanine mutations are introduced at every residue in the molecule, and the resultant mutant molecules are tested for biological activity (i.e xyloglucanase activity) to identify amino acid residues that are critical to the activity of the molecule. See also, Hilton et al., J. Biol. Chem. 271:4699-4708, 1996. The active site of the enzyme or other biological interaction can also be determined by physical analysis of structure, as determined by such techniques as nuclear magnetic resonance, crystallography, electron diffraction or photoaffinity labeling, in conjunction with mutation of putative contact site amino acids. See, for example, de Vos et al., Science 255: 306-312. 1992; Smith et al., J. Mol. Biol. 224:899-904. 1992; Wlodaver et al. , FEBS Lett. 309: 59-64, 1992. The identities of essential amino acids can also be inferred from analysis of homologies with polypeptides which are related to a polypeptide according to the invention. Multiple amino acid substitutions can be made and tested using known methods of mutagenesis, recombination and/or shuffling followed by a relevant screening procedure, such as those disclosed by Reidhaar-Olson and Sauer (Science 241: 53-57 , 1988), Bowie and Sauer (Proc. Natl. Acad. Sci. USA 86:2152-2156, 1989), W095/17413, or WO 95/22625. Briefly, these authors disclose methods for simultaneously randomizing two or more positions in a polypeptide, or recombination/shuffling of different mutations (W095/17413, W095/22625) , followed by selecting for functional a polypeptide, and then sequencing the mutagenized polypeptides to determine the spectrum of allowable substitutions at each position. Other methods that can be used include phage display (e.g., Lowman et al. , Biochem. 30: 10832- 10837, 1991; Ladner et al., U.S. Patent No. 5,223,409; Huse, WIPO Publication WO 92/06204) and region-directed mutagenesis (Derbyshire et al., Gene _6:145, 1986; Ner et al., DNA 1:127, 1988) . Mutagenesis/shuffling methods as disclosed above can be combined with high-throughput, automated screening methods to detect activity of cloned, mutagenized polypeptides in host cells. Mutagenized DNA molecules that encode active polypeptides can be recovered from the host cells and rapidly sequenced using modern equipment. These methods allow the rapid determination of the importance of individual amino acid residues in a polypeptide of interest, and can be applied to polypeptides of unknown structure . Using the methods discussed above, one of ordinary skill in the art can identify and/or prepare a variety of polypeptides that are substantially homologous to SEQ ID NO: 4 or residues 30 to 261 of SEQ ID NO: 2 and retain the xyloglucanase activity of the wild-type protein. The xyloglucanase enzyme of the invention may, in addition to the enzyme core comprising the catalytically domain, also comprise a cellulose binding domain (CBD) , the cellulose binding domain and enzyme core (the catalytically active domain) of the enzyme being operably linked. The cellulose binding domain (CBD) may exist as an integral part the encoded enzyme, or a CBD from another origin may be introduced into the xyloglucanase thus creating an enzyme hybride. In this context, the term "cellulose-binding domain" is intended to be understood as defined by Peter Tomme et al. "Cellulose-Binding Domains: Classification and Properties" in "Enzymatic Degradation of Insoluble Carbohydrates", John N. Saddler and Michael H. Penner (Eds.), ACS Symposium Series, No. 618, 1996. This definition classifies more than 120 cellulose-binding domains into 10 families (I-X) , and demonstrates that CBDs are found in various enzymes such as cellulases, xylanases, mannanases, arabinofuranosidases, acetyl esterases and chitinases. CBDs have also been found in algae, e.g. the red alga Porphyra purpurea as a non-hydrolytic polysaccharide-binding protein, see Tomme et al. , op . cit . However, most of the CBDs are from cellulases and xylanases, CBDs are found at the N and C termini of proteins or are internal. Enzyme hybrids are known in the art, see e.g. WO 90/00609 and WO 95/16782, and may be prepared by transforming into a host cell a DNA construct comprising at least a fragment of DNA encoding the cellulose-binding domain ligated, with or without a linker, to a DNA sequence encoding the xyloglucanase and growing the host cell to express the fused gene. Enzyme hybrids may be described by the following formula: CBD - MR - X wherein CBD is the N-terminal or the C-terminal region of an amino acid sequence corresponding to at least the cellulose- binding domain; MR is the middle region (the linker) , and may be a bond, or a short linking group preferably of from about 2 to about 100 carbon atoms, more preferably of from 2 to 40 carbon atoms; or is preferably from about 2 to to about 100 amino acids, more preferably of from 2 to 40 amino acids; and X is an N-terminal or C-terminal region of a polypeptide encoded by the polynucleotide molecule of the invention. The xyloglucan substrate In addition to the aforesaid about xyloglucan it should be noted that xyloglucan from tamarind seeds supplied by Megazyme, Australia has a complex branched structure with glucose, xylose, galactose and arabinose in the ratio of 45:36:16:3. Accordingly, it is strongly believed that an enzyme showing catalytic activity on this xyloglucan also has catalytic activity on other xyloglucan structures from different sources (angiosperms ot gymnosperms) . Use in the detergent industry During washing and wearing, dyestuff from dyed fabrics or garment will conventionally bleed from the fabric which then looks faded and worn. Removal of surface fibers from the fabric will partly restore the original colours and looks of the fabric. By the term "colour clarification", as used herein, is meant the partly restoration of the initial colours of fabric or garment throughout multiple washing cycles. The term "de-pilling" denotes removing of pills from the fabric surface. The term "soaking liquor" denotes an aqueous liquor in which laundry may be immersed prior to being subjected to a conventional washing process. The soaking liquor may contain one or more ingredients conventionally used in a washing or laundering process. The term "washing liquor" denotes an aqueous liquor in which laundry is subjected to a washing process, i.e. usually a combined chemical and mechanical action either manually or in a washing machine. Conventionally, the washing liquor is an aqueous solution of a powder or liquid detergent composition. The term "rinsing liquor" denotes an aqueous liquor in which laundry is immersed and treated, conventionally immediately after being subjected to a washing process, in order to rinse the laundry, i.e. essentially remove the detergent solution from the laundry. The rinsing liquor may contain a fabric conditioning or softening composition. The laundry subjected to the method of the present invention may be conventional washable laundry. Preferably, the major part of the laundry is sewn or unsewn fabrics, including knits, wovens, denims, yarns, and toweling, made from cotton, cotton blends or natural or manmade cellulosics (e.g. originating from xylan-containing cellulose fibers such as from wood pulp) or blends thereof. Examples of blends are blends of cotton or rayon/viscose with one or more companion material such as wool, synthetic fibers (e.g. polyamide fibers, acrylic fibers, polyester fibers, polyvinyl alcohol fibers, polyvinyl chloride fibers, polyvinylidene chloride fibers, polyurethane fibers, polyurea fibers, aramid fibers) , and cellulose-containing fibers (e.g. rayon/viscose, ramie, flax/ linen, jute, cellulose acetate fibers, lyocell) .

In general, bleaching compounds are optional added components in non-liquid formulations, e.g. granular detergents. The bleaching agent component for use herein can be any of the bleaching agents useful for detergent compositions including oxygen bleaches as well as others known in the art. The bleaching agent suitable for the present invention can be an activated or non-activated bleaching agent. One category of oxygen bleaching agent that can be used encompasses percarboxylic acid bleaching agents and salts thereof. Suitable examples of this class of agents include magnesium monoperoxyphthalate hexahydrate, the magnesium salt of meta-chloro perbenzoic acid, 4-nonylamino-4-oxoperoxybutyric acid and diperoxydodecanedioic acid. Such bleaching agents are disclosed in US 4,483,781, US 740,446, EP 0 133 354 and US 4,412,934. Highly preferred bleaching agents also include 6- nonylamino-6-oxoperoxycaproic acid as described in US 4,634,551. Another category of bleaching agents that can be used encompasses the halogen bleaching agents. Examples of hypohalite bleaching agents, for example, include trichloro isocyanuric acid and the sodium and potassium dichloroisocyanurates and N- chloro and N-bromo alkane sulphonamides. Such materials are normally added at 0.5-10% by weight of the finished product, preferably 1-5% by weight. The hydrogen peroxide releasing agents can be used in combination with bleach activators such as tetra- acetylethylenediamine (TAED) , nonanoyloxybenzenesulfonate (NOBS, described in US 4,412,934), 3 , 5-trimethyl- hexsanoloxybenzenesulfonate (ISONOBS, described in EP 120 591) or pentaacetylglucose (PAG) , which are perhydrolyzed to form a peracid as the active bleaching species, leading to improved bleaching effect. In addition, very suitable are the bleach activators C8 (6-octanamido-caproyl) oxybenzene-sulfonate, C9(6- nonanamido caproyl) oxybenzenesulfonate and CIO (6-decanamido caproyl) oxybenzenesulfonate or mixtures thereof. Also suitable activators are acylated citrate esters such as disclosed in European Patent Application No. 91870207.7. Useful bleaching agents, including peroxyacids and bleaching systems comprising bleach activators and peroxygen bleaching compounds for use in cleaning compositions according to the invention are described in application USSN 08/136,626. The hydrogen peroxide may also be present by adding an enzymatic system (i.e. an enzyme and a substrate therefore) which is capable of generation of hydrogen peroxide at the beginning or during the washing and/or rinsing process. Such enzymatic systems are disclosed in European Patent Application EP 0 537 381. Bleaching agents other than oxygen bleaching agents are also known in the art and can be utilized herein. One type of non-oxygen bleaching agent of particular interest includes photoactivated bleaching agents such as the sulfonated zinc and- /or aluminium phthalocyanines. These materials can be deposited upon the substrate during the washing process. Upon irradiation with light, in the presence of oxygen, such as by hanging clothes out to dry in the daylight, the sulfonated zinc phthalocyanine is activated and, consequently, the substrate is bleached. Preferred zinc phthalocyanine and a photoactivated bleaching process are described in US 4,033,718. Typically, detergent composition will contain about 0.025% to about 1.25%, by weight, of sulfonated zinc phthalocyanine. Bleaching agents may also comprise a manganese catalyst.

Suds suppressors Another optional ingredient is a suds suppressor, exemplified by silicones, and silica-silicone mixtures. Silicones can generally be represented by alkylated polysiloxane materials, while silica is normally used in finely divided forms exemplified by silica aerogels and xerogels and hydrophobic silicas of various types.

Other useful polymeric materials are the polyethylene glycols, particularly those of molecular weight 1000-10000, more particularly 2000 to 8000 and most preferably about 4000. These are used at levels of from 0.20% to 5% more preferably from 0.25% to 2.5% by weight. These polymers and the previously mentioned homo- or co-polymeric poly-carboxylate salts are valuable for improving whiteness maintenance, fabric ash deposition, and cleaning performance on clay, proteinaceous and oxidizable soils in the presence of transition metal impurities. Soil release agents useful in compositions of the present invention are conventionally copolymers or terpolymers of terephthalic acid with ethylene glycol and/or propylene glycol units in various arrangements. Examples of such polymers are disclosed in US 4,116,885 and 4,711,730 and EP 0 272 033. A particular preferred polymer in accordance with EP 0 272 033 has the formula: (CH 3 (PEG) 4 3)o. 7 5(POH)o. 25 [T-PO) 2 .8(T- PEG)o. 4 ]T(POH)o. 25 ((PEG) 43 CH 3 )o. 75 where PEG is -(OC 2 H )0-, PO is (OC 3 H 6 0) and T is (pOOC 6 H CO) .

The target is to obtain a polymer capped at both end by sulphobenzoate groups, "primarily", in the present context most of said copolymers herein will be endcapped by sulphobenzoate groups. However, some copolymers will be less than fully capped, and therefore their end groups may consist of monoester of ethylene glycol and/or 1, 2-propanediol, thereof consist "secondarily" of such species. The selected polyesters herein contain about 46% by weight of dimethyl terephthalic acid, about 16% by weight of 1,2- propanediol, about 10% by weight ethylene glycol, about 13% by weight of dimethyl sulfobenzoic acid and about 15% by weight of sulfoisophthalic acid, and have a molecular weight of about 3.000. The polyesters and their method of preparation are 5 described in detail in EP 311 342. Softening agents Fabric softening agents can also be incorporated into laundry detergent compositions in accordance with the present 0 invention. These agents may be inorganic or organic in type.

Examples of blends are blends of cotton or rayon/viscose with one or more companion material such as wool, synthetic fibers (e.g. polyamide fibers, acrylic fibers, polyester fibers, polyvinyl alcohol fibers, polyvinyl chloride fibers, polyvinylidene chloride fibers, polyurethane fibers, polyurea fibers, aramid fibers) , and cellulose-containing fibers (e.g. rayon/viscose, ramie, hemp, flax/linen, jute, cellulose acetate fibers, lyocell) . The preparation of the present invention is useful in the cellulosic fiber processing industry for the pretreatment or retting of fibers from hemp, flax or linen. The processing of cellulosic material for the textile industry, as for example cotton fiber, into a material ready for garment manufacture involves several steps: spinning of the fiber into a yarn; construction of woven or knit fabric from the yarn and subsequent preparation, dyeing and finishing operations. Woven goods are constructed by weaving a filling yarn between a series of warp yarns; the yarns could be two different types. Knitted goods are constructed by forming a network of interlocking loops from one continuous length of yarn. The cellulosic fibers can also be used for non-woven fabric. The preparation process prepares the textile for the proper response in dyeing operations. The sub-steps involved in preparation are desizing (for woven goods) , scouring and bleaching. A one step combined scour/bleach process is also used by the industry. Although preparation processes are most commonly employed in the fabric state; scouring, bleaching and dyeing operations can also be done at the fiber or yarn stage. The processing regime can be either batch or continuous with the fabric being contacted by the liquid processing stream in open width or rope form. Continuous operations generally use a saturator whereby an approximate equal weight of chemical bath per weight of fabric is applied to the fabric, followed by a heated dwell chamber where the chemical reaction takes place. A washing section then prepares the fabric for the next processing step. Batch processing generally takes place in one processing bath whereby the fabric is contacted with approximately 8 -15 5 times its weight in chemical bath. After a reaction period, the chemicals are drained, fabric rinsed and the next chemical is applied. Discontinuous pad-batch processing involves a saturator whereby an approximate equal weight of chemical bath per weight of fabric is applied to the fabric, followed by a dwell period 0 which in the case of cold pad-batch might be one or more days. Woven goods are the prevalent form of textile fabric construction. The weaving process demands a "sizing" of the warp yarn to protect it from abrasion. Starch, polyvinyl alcohol (PVA) , carboxymethyl cellulose, waxes and acrylic binders are 5 examples of typical sizing chemicals used because of availability and cost. The size must be removed after the weaving process as the first step in preparing the woven goods. The sized fabric in either rope or open width form is brought in contact with the processing liquid containing the desizing 0 agents. The desizing agent employed depends upon the type of size to be removed. For PVA sizes, hot water or oxidative processes are often used. The most common sizing agent for cotton fabric is based upon starch. Therefore most often, woven cotton fabrics are desized by a combination of hot water, the 5 enzyme α-amylase to hydrolyze the starch and a wetting agent or surfactant. The cellulosic material is allowed to stand with the desizing chemicals for a "holding period" sufficiently long to accomplish the desizing. The holding period is dependent upon the type of processing regime and the temperature and can vary 30 from 15 minutes to 2 hours, or in some cases, several days. Typically, the desizing chemicals are applied in a saturator bath which generally ranges from about 15°C to about 55°C. The fabric is then held in equipment such as a "J-box" which provides sufficient heat, usually between about 55°C and about 35 100°C, to enhance the activity of the desizing agents. The chemicals, including the removed sizing agents, are washed away from the fabric after the termination of the holding period. In order to ensure a high whiteness or a good wettability and resulting dyeability, the size chemicals and other applied chemicals must be thoroughly removed. It is generally believed that an efficient desizing is of crucial importance to the following preparation processes: scouring and bleaching. The scouring process removes much of the non-cellulosic compounds naturally found in cotton. In addition to the natural non-cellulosic impurities, scouring can remove dirt, soils and residual manufacturing introduced materials such as spinning, coning or slashing lubricants. The scouring process employs sodium hydroxide or related causticizing agents such as sodium carbonate, potassium hydroxide or mixtures thereof. Generally an alkali stable surfactant is added to the process to enhance solubilization of hydrophobic compounds and/or prevent their redeposition back on the fabric. The treatment is generally at a high temperature, 80°C - 100°C, employing strongly alkaline solutions, pH 13-14, of the scouring agent. Due to the nonspecific nature of chemical processes not only are the impurities but the cellulose itself is attacked, leading to damages in strength or other desirable fabric properties. The softness of the cellulosic fabric is a function of residual natural cotton waxes. The non-specific nature of the high temperature strongly alkaline scouring process cannot discriminate between the desirable natural cotton lubricants and the manufacturing introduced lubricants. Furthermore, the conventional scouring process can cause environmental problems due to the highly alkaline effluent from these processes. The scouring stage prepares the fabric for the optimal response in bleaching. An inadequately scoured fabric will need a higher level of bleach chemical in the subsequent bleaching stages. The bleaching step decolorizes the natural cotton pigments and removes any residual natural woody cotton trash components not completely removed during ginning, carding or scouring. The main process in use today is an alkaline hydrogen peroxide bleach. In many cases, especially when a very high whiteness is not needed, bleaching can be combined with scouring. It is contemplated that the scouring step can be carried out using the xyloglucanase or xyloglucanase preparation of the present invention in combination with a few other enzyme activities at a temperature of about 50°C - 80°C and a pH of about 7-11, thus substituting or supplementing the highly causticizing agents.

This strain is the B. subtilis DN1885 with disrupted apr and npr genes (Diderichsen, B., Wedsted, U., Hedegaard, L., Jensen, B. R., Sjøholm, C.

PSJ1678 (see WO 94/19454) . pMOL944. This plasmid is a pUBHO derivative essentially containing elements making the plasmid propagatable m Bacillus subtilis, kanamycm resistance gene and having a strong promoter and signal peptide cloned from the amyL gene of B . licheniformis ATCC 14580. The signal peptide contains a SacII site making it convenient to clone the DNA encoding the mature part of a protein in-fusion w th the signal peptide. Th s results m the expression of a Pre-protem which is directed towards the exterior of the cell. The plasmid was constructed by means of ordinary genetic engineering and is briefly described the following. Construction of pMOL944: The pUBHO plasmid (McKenzie, T. et al . , 1986,) was digested with the unique restriction enzyme Neil. A PCR fragment amplified from the amyL promoter encoded on the plasmid pDN1981 (Jørgensen et al.,1990) was digested with Neil and inserted in the Neil digested pUBHO to give the plasmid pSJ2624.

The plasmid pSJ2624 was then digested with Sad and NotI and a new PCR fragment amplified on amyL promoter encoded on the pDN1981 was digested with Sad and NotI and this DNA fragment was inserted the SacI-NotI digested pSJ2624 to give the plasmid pSJ2670. This cloning replaces the first amyL promoter cloning with the same promoter but in the opposite direction.

Fermentation procedure: The fungal strains were grown in shake flasks under the following growth conditions: Media: A, B or C (see list of media) Temperature: 26°C RPM: A, stationary B and C, 125 - 200 Incubation time: A, 6 - 30 days B and C , 2 - 21 days Bacteria were grown in shake flasks containing medium D or E at 30°C with 250 rpm shaking for 3-4 days. Xyloglucanase assay (XGU) : The xyloglucanase activity is measured using AZCL- xyloglucan from Megazyme, Australia, as substrate. A solution of 0.2 % of the blue substrate is suspended in a 0.1 M phosphate buffer pH 7.5 under stirring. The solution is distributed under stirring to 1.5 ml Eppendorf tubes (0.75 ml to each) , 50 μl enzyme solution is added and they are incubated in an Eppendorp Thermomixer model 5436 for 20 min. at 40°C with a mixing of 1200 rpm. After incubation the coloured solution is separated from the solid by 4 min. centrifugation at 14,000 rpm and the absorbance of the supernatant is measured at 600 nm. One XGU units is defined as the amount of enzyme resulting in an absorbance of 0.24 in a 1 cm cuvette at 600 nm. Isoelectric focusing: Isoelectric focusing was carried out in precast Ampholine PAG plates pH 3.5-9.5 (Pharmacia, Sweden) according to the manufacturer's instructions. The samples were applied in duplicate and after electrophoresis the gel was divided into two. An overlay containing 1% agarose and 0.4% AZCL xyloglucan in water was poured onto one half of the gel, a similar overlay containing AZCL HE cellulose was poured onto the other half. Incubation at 30°C for 2-16 hours. Enzyme activity was identified by blue zones. General molecular biology methods: DNA manipulations and transformations were performed using standard methods of molecular biology (Sambrook et al. (1989) Molecular cloning: A laboratory manual, Cold Spring Harbor lab., Cold Spring Harbor, NY; Ausubel, F. M. et al. (eds.) "Current protocols in Molecular Biology". John Wiley and Sons, 1995; Harwood, C. R. , and Cutting, S. M. (eds.) "Molecular Biological Methods for Bacillus". John Wiley and Sons, 1990). Enzymes for DNA manipulations were used according to the specifications of the suppliers. The following examples illustrate the invention. 5 EXAMPLE 1 Screening for microorganisms producing alkaline xyloglucanase The microorganisms to be screened were grown in a liquid culture as described in the Materials and Methods section. After centrifugation the culture supernatants were tested for 10 xyloglucanase and cellulase activity. The following assays were used: agarose plates containing 1% agarose in 0.08 M Britton- Robinson buffer pH 7 or pH 9 , and 0.2% AZCL xyloglucan and 0.2% AZCL HE cellulose, respectively, 10 ml samples were applied into d = 4 mm holes in the agarose plates, incubation at 30°C for 2- 15 16 hours. Enzyme activity was identified by blue halos. Culture broths with good activity on AZCL xyloglucan and no or low activity on AZCL HE cellulose were further tested by isoelectric focusing (IEF) as described in the Materials and Methods section. The microorganisms listed in the Materials and 20 Methods section were found to produce an enzyme with activity on AZCL xyloglucan which by IEF was separable from activity on AZCL HE cellulose. When screening for xyloglucanase activity also cellulase activity was found, and it was determined whether both activities derives from the same enzyme. This was done by 25 separation of the enzymes by IEF isoelctric focusing which separates the protein according to the charge or pi . After this separation the different enzymatic activities was again identified using overlayer techniques. The sample was run at two parallel wells: one stained for xyloglucanase and another for 30 AZCL HE- cellulose. If the same lane has both activities it is a cellulase, if only one lane has xyloglucanase and no cellulase activity it is a xyloglucanase which can be further characterized either by purification or by cloning. 35 EXAMPLE 2 Production of a Bacillus licheniformis xyloglucanase (XG) This example illustrates a method for producing xyloglucanase from Bacillus licheniformis . Bacillus licheniformis , ATCC 14580, was grown in shake flasks using the substrate PS 1 (20% sucrose and 5% soy flakes and 1% sodium phosphate) at 30°C with 250 rpm shaking for 4 days. The culture broth (total 10 litres) was adjusted to pH 7.5 with NaOH, followed by treatment with 50 ml of a cationic flocculation agent under stirring at room temperature and subsequently 470 ml of a 0.1% solution of an anionic flocculation agent. The flocculated material was separated by centrifugation using a Sorval RC 3B 10.000 rpm for 30 min. The supernatant was clarified using a Whatman glass filter number F. A total of 9 litres was obtained with an activity of 10 XGU per ml. The liquid was concentrated to 1.5 litres on a filtron with a cut off at 10 kDa. Bacitracin cross linked to Sepharose was used for affinity column chromatography for removal of the proteases. Then the not bound material was adjusted to pH 5.0 using acetic acid and applied to a SP-Sepharose column adjusted with 20 mM sodium acetate buffer pH 5.0. The XG activity was eluted from the column by using a 0.5 M NaCl gradient. The fractions containing XG activity was pooled and concentrated on an Amicon cell with a GR 81 polysulfon membrane with a cut off at 8 kDa. The concentrated solution containing 363 XGU per ml was applied to size chromatography using a Superdex 200 column equilibrated with a buffer of 0.1 M sodium acetate pH 6.0. The pure XG 1 eluted with an apparent molecular weight of 26 kDa and gave a single band in SDS-PAGE of 26 kDa. The specific activity was determined to 221 XGU per A.280. EXAMPLE 3 Characterisation of a Bacillus licheniformis xyloglucanase The amino acid sequence of the enzyme produced as described in Example 2 was obtained after SDS-PAGE and electroblotting of the 26 kDa protein. The amino acid sequence is listed in the appended SEQ ID No: 2. This amino acid shows highest homology with glycosyl hydrolases from Family 12 which at present are classified as endo-beta-l,4-glucanases (EC 3.2.1.4): 65% homology with the family 12 Erwinia carotovora β-l,4-glucan glucanohydrolase (celS - P16630 Swissprot) . Accordingly, the present invention further relates to an enzyme which has the amino acid sequence listed in SEQ ID NO: 2 or has an amino acid sequence which is at least 70%, preferably at least 75%, more preferably at least 80%, more preferably at least 85%, even more preferably at least 90%, especially at least 95%, homologous therewith. The obtained Bacillus licheniformis xyloglucanse enzyme was analysed using Megazyme AZCL xyloglucan for xyloglucanase activity determination and AZCL HE cellulose for endoglucanase activity determination. The relative release of blue colour was 40 times higher on the xyloglucan substrate compared with the HE cellulose using the same amount of purified enzyme. The same result was found for the acidic Aspergillus aculeatus xyloglucanase enzyme (EG II) described in the patent application WO 94/14953 which also showed 2% relative activity against HE cellulose. Temperature optimum The AZCL xyloglucan from Megazyme was also used for determination of temperature optimum. The activity was measured at different temperatures after incubation with the xyloglucanase of Example 2 for 20 minutes and the release of blue colour was determined at 600 nm. The major part of the colour was released at 60°C, but still 50% relative activity was obtained at 70° C. pH activity profile For obtaining a realistic pH activity profile, the activity determinations were carried out using buffers having a pKa value within 1.0 of the actual pH. The following buffer systems were used: pH 4-5.5 sodium acetate, pH 6 Mes buffer (Sigma), pH 6.5 - 7.5 Mops buffer (Sigma), pH 8-8.5 Barbiturate, pH 9-10.5 Glycine. The pH was measured after incubation in a parallel handled tube. Incubation 20 min. at 40° C. Final substrate concentration 1.33 gram xyloglucan per 1. This is the _sT M (see below for steady state at pH 7.5). The activity was determined after measurement of the formation of reducing ends as described for steady state kinetic. EXAMPLE 4 Comparison example: Steady state kinetics on soluble xyloglucan and CMC A method for determination of activity against xyloglucan has been developed. The substrate is xyloglucan (amyloid) from tamarind seeds (the substrate is commercially available from Megazyme) . Buffer 0.1 M sodium phosphate pH 7.5. The substrate is prepared as a stock solution containing 5 gram per 1 in buffer. After mixing it is heated using a magnetic stirrer until a clear solution is obtained. The solution is then cooled to 40 °C and kept in a temperature controlled water bath at 40 °C. The diluted enzyme solution of 0.5 ml is preheated for 10 min. and mixed with 1.0 ml substrate and incubated for 20 min. The formation of reducing sugars is determined by using p- hydroxy-benzoic-acid-hydrazide (PHBAH) modified from Lever (1972) using 5 gram of potassium sodium tartrate in addition to 1.5 gram of PHBAH. Glucose is used as reference for determination of the reducing groups. The apparent catalytic properties of 2 known cellulases (endo-beta-1, 4-glucanases) on xyloglucan from tamarind seeds was measured: a. EG I from Humicola insolens (classified as belonging to family 7 of glycosyl hydrolases) disclosed in WO 95/24471. b. EG III from Trichoderma (classified as belonging to family 12 of glycosyl hydrolases) disclosed in US patent US 5,475,101. All the enzymes were purified to high homogeneity giving a single band in SDS-PAGE and the molar extinction coefficient was used for calculation of the enzyme concentration. The determination was based on different concentrations of the substrate from 0.25 to 3.3 gram per litre. The kinetic determination was according to the computer program Grafit and assuming Michelis Menten kinetic.

The ligation mixture was used to transform competent B . subtilis PL2306. The transformed cells were plated onto LBPG- 10 10 μg/ml of Kanamycin -0.1% AZCL-Xyloglucan-agar plates. After 18 hours incubation at 37°C cells positively expressing the cloned Xyloglucanase were seen as colonies surrounded by blue halos. One such positive clone was restreaked several times on agar plates as used above, this clone was called MB563. The 15 clone MB563 was grown overnight in TY-lOμg/ml Kanamycin at 37 °C, and next day 1 ml of cells were used to isolate plasmid from the cells using the Qiaprep Spin Plasmid Miniprep Kit #27106 according to the manufacturers recommendations for B. subtilis plasmid preparations. 20 Expression and purification of B. agaradhaerens xyloglucanase: MB563 was grown in 25 x 200 ml BPX media with 10 μg/ml of Kanamycin in 500 ml two baffled shakeflasks for 5 days at 37°C at 300 rpm. 25 EXAMPLE 7 Characterisation of a Bacillus agaradhaerens xyloglucanase Purification and characterization: 7000 ml shake flask culture fluid from Bacillus with the 30 clone MB 563 expressed as described in example 6 was received. The fermentation medium was adjusted to pH 7.5 with NaOH and flocculated using cationic flocculation agent C521 (10% solution) and 0.1% solution of anionic agent A130: To 7000 ml of fermentation medium was added 168 ml of C521 (10%) simultaneous 35 with 335 ml of A130 under stirring at room temperature. The flocculated material was separated by centrifugation using a Sorval RC 3B centrifuge at 10,000 rpm for 30 minutes. The supernatant was clarified using Whatman glass filter number F. In total was obtained 6500 ml of clear solution containing 227,500 XGU units. The clear solution of 2500 ml was applied to a 1000 ml Q- Sepharose column equilibrated with 50 mM Tris buffer pH 7.0. The bound enzyme was eluted using a NaCl gradient. The partly purified product was concentrated using an Amicon ultrafiltration cell with a membrane with a cut-off value of 6 kDa. Total 70.000 XGU units and 2.5 gram of enzyme protein was obtained. The pure sample gave a single band in SDS-PAGE with a apparent molecular weight of 61 kDa. A molar extinction coefficient of 123,040 was used for calculation of enzyme protein concentration and is based on the amino acid composition deducted from the DNA sequence. The concentrated fraction was formulated with 40% sorbitol and used for enzyme trials in detergent and textile applications. Immunological methods: Highly purified Bacillus agaradhaerens XEGl obtained from clone MB 563 was used for production of antiserum. The immunization procedure was conducted at DAKO using rabbits. Each rabbit was immunized with 100 μl cellulase (0.4 mg protein per ml) mixed with 100 μl adjuvant. Each rabbit was immunized 15 times with one weeks interval. The rabbit serum was collected and the gammaglobulin purified from the serum. Temperature optimum: The AZCL xyloglucan from Megazyme was also used for determination of temperature optimum. The activity was measured at different temperatures after incubation with the Bacillus agaradhaerens XEGl for 20 minutes and the release of blue colour was determined at 600 nm. The major part of the colour was released at 50°C, but still 20% relative activity was obtained at 60°C. Steady state kinetics on soluble xyloglucan and CMC: The method for determination of activity against xyloglucan described in example 4 was applied to the . agaradhaerens xyloglucanase of the invention. The substrate was diluted to at least 8 different concentrations with 4 below the apparent Km (see below) . The following apparent catalytic properties of the Bacillus agaradhaerens XEGl (endo-beta-1, -xylo-glucanases) on xyloglucan from tamarind seeds were found: At pH 7.5 the kcat of 183 per sec and a apparent Km of 0.05 gram per 1 was obtained. For comparison the activity on CMC (Degree of substitution 0.7 and a degree of polymerization of 200) using the same steady state kinetic method with 8 different substrate concentrations in duplicate below the Km the following data was obtained: kcat of 64 per sec and a Km of 2.2 gram per 1, indicating that this enzyme prefer xyloglucan from carboxymethyl cellulose. Alkaline activity, at pH 10 using a glycine buffer and xyloglucan substrate, resulted in a Kcat of 90 per sec and a apparent Km of 0.08 gram per 1 indicate that this xyloglucanase has a very high alkaline activity. The pH activity profile using blue Megazyme AZCL xyloglucan indicate that the enzyme has more than 50% relative activity in the pH interval of 5.0 to 10.5. In a detergent matrices using the blue Megazyme substrate the following data was obtained. In US Tide powder detergent 1 gram per 1 with 9 German hardness of water 66% relative activity to buffer pH 7.5. Using European conditions and powder Ariel in 5 gram per 1 and 18 German hardness the relative activity of 86% was obtained. These data indicate that the Bacillus agaradhaerens XEGl is well suited to be used in detergent matrices. LITERATURE Ausubel, F. M. et al . (eds.) "Current protocols in Molecular Biology".
