     As used herein, the term “cellulase” refers to any enzyme that is capable of hydrolyzing the 1,4 beta-D-glucosidic linkages in celluloses. The term encompasses endoglucanases, exoglucanases (i.e., cellobiohydrolases), and beta-glucosidases. It is not intended that the present invention be limited to any particular cellulase, although in some embodiments, one particularly preferred cellulase is PURADAX® HA (commercially available from Danisco US Inc., Genencor Division). 
     As used herein, the term “compatible,” means that the cleaning composition materials do not reduce the enzymatic activity of the cellulase enzyme(s) provided herein to such an extent that the cellulase(s) is/are not effective as desired during normal use situations. Specific cleaning composition materials are exemplified in detail hereinafter. 
     As used herein, “effective amount of enzyme” refers to the quantity of enzyme necessary to achieve the enzymatic activity required in the specific application. Such effective amounts are readily ascertained by one of ordinary skill in the art and are based on many factors, such as the particular enzyme used, the cleaning application, the specific composition of the cleaning composition, and whether a liquid or dry (e.g., granular) composition is required, and the like. 
     As used herein, the phrase “detergent stability” refers to the stability of a detergent composition. In some embodiments, the stability is assessed during the use of the detergent, while in other embodiments, the term refers to the stability of a detergent composition during storage. 
     As used herein, the phrase, “stability to proteolysis” refers to the ability of a protein (e.g., an enzyme) to withstand proteolysis. It is not intended that the term be limited to the use of any particular protease to assess the stability of a protein. 
     As used herein, “oxidative stability” refers to the ability of a protein to function under oxidative conditions. In particular, the term refers to the ability of a protein to function in the presence of various concentrations of H 2 O 2 , peracids and other oxidants. Stability under various oxidative conditions can be measured either by standard procedures known to those in the art and/or by the methods described herein. A substantial change in oxidative stability is evidenced by at least about a 5% or greater increase or decrease (in most embodiments, it is preferably an increase) in the half-life of the enzymatic activity, as compared to the enzymatic activity present in the absence of oxidative compounds. 
     As used herein, “pH stability” refers to the ability of a protein to function at a particular pH. In general, most enzymes have a finite pH range at which they will function. In addition to enzymes that function in mid-range pHs (around pH 7), there are enzymes that are capable of working under conditions with very high or very low pHs. Stability at various pHs can be measured either by standard procedures known to those in the art and/or by the methods described herein. A substantial change in pH stability is evidenced by at least about 5% or greater increase or decrease (in most embodiments, it is preferably an increase) in the half-life of the enzymatic activity, as compared to the enzymatic activity at the enzyme&#39;s optimum pH. However, it is not intended that the present invention be limited to any pH stability level nor pH range. 
     As used herein, “thermal stability” and “thermostability” refer to the ability of a protein to function at a particular temperature. In general, most enzymes have a finite range of temperatures at which they will function. In addition to enzymes that work in mid-range temperatures (e.g., room temperature), there are enzymes that are capable of working in very high or very low temperatures. Thermal stability can be measured either by known procedures or by the methods described herein. A substantial change in thermal stability is evidenced by at least about 5% or greater increase or decrease (in most embodiments, it is preferably an increase) in the half-life of the catalytic activity of an enzyme when exposed to given temperature. However, it is not intended that the present invention be limited to any temperature stability level nor temperature range. 
     As used herein, the term “chemical stability” refers to the stability of a protein (e.g., an enzyme) towards chemicals that may adversely affect its activity. In some embodiments, such chemicals include, but are not limited to hydrogen peroxide, peracids, anionic detergents, cationic detergents, non-ionic detergents, chelants, etc. However, it is not intended that the present invention be limited to any particular chemical stability level nor range of chemical stability. As used herein, the terms “detergent composition” and “detergent formulation” are used in reference to mixtures which are intended for use in a wash medium for the cleaning of soiled objects. In some embodiments, the term is used in reference to detergents used to clean dishes, cutlery, etc. (e.g., “dish detergents” or “dishwashing detergents”). It is not intended that the present invention be limited to any particular detergent formulation or composition. Indeed, it is intended that in addition to detergents that contain at least one protease of the present invention, the term encompasses detergents that contain surfactants, transferase(s), hydrolytic enzymes, oxido reductases, builders, bleaching agents, bleach activators, bluing agents and fluorescent dyes, caking inhibitors, masking agents, enzyme activators, antioxidants, and solubilizers. 
     As used herein, “dishwashing composition” refers to all forms of compositions for cleaning dishware, including cutlery, including but not limited to granular and liquid forms. It is not intended that the present invention be limited to any particular type or dishware composition. Indeed, the present invention finds use in cleaning dishware (e.g., dishes, including, but not limited to plates, cups, glasses, bowls, etc.) and cutlery (e.g., utensils, including but not limited to spoons, knives, forks, serving utensils, etc.) of any material, including but not limited to ceramics, plastics, metals, china, glass, acrylics, etc. The term “dishware” is used herein in reference to both dishes and cutlery. 
     As used herein, “non-phosphate containing dishwashing detergents” are detergents that contain no more than 0.5% phosphorus (i.e., phosphorus is a trace element). 
     As used herein, “wash performance” of mutant protease refers to the contribution of a mutant protease enzyme to dishwashing that provides additional cleaning performance to the detergent without the addition of the mutant protease to the composition. Wash performance is compared under relevant washing conditions. 
     The term “relevant washing conditions” is used herein to indicate the conditions, particularly washing temperature, time, washing mechanics, sud concentration, type of detergent and water hardness, actually used in households in a dish detergent market segment. 
     The term “improved wash performance” is used to indicate that a better end result is obtained in stain removal from dishware and/or cutlery under relevant washing conditions, or that less enzyme, on weight basis, is needed to obtain the same end result relative to the corresponding wild-type enzyme. 
     The term “retained wash performance” is used to indicate that the wash performance of a mutant enzyme, on weight basis, is at least 80% relative to the corresponding wild-type enzyme under relevant washing conditions. 
     As used herein, the term “comparative performance” in the context of cleaning activity refers to at least about 60%, at least about 70%, at least about 80% at least about 90%, or at least about 95% of the cleaning activity of a comparative enzyme (e.g., commercially available enzymes). 
     As used herein, the term “specific performance” refers to the cleaning of specific stains per unit of active protein. In some embodiments, the specific performance is determined using stains such as spaghetti mix, egg yolk, egg/milk, minced meat, tea, milk, porridge, etc. 
     As used herein, the term “disinfecting” refers to the removal of contaminants from the surfaces, as well as the inhibition or killing of microbes on the surfaces of items. It is not intended that the present invention be limited to any particular surface, item, or contaminant(s) or microbes to be removed. 
     As used herein, the terms “spaghetti soil mix” and “spaghetti mix” refer to the “dishwashing test soil” or stain described in Example 1, in which spaghetti sauce, pasta, cheese and meat are combined to produce a soil suitable for use in testing cleaning performance of an enzyme and/or detergent composition. In some embodiments, the dishwashing test soil further comprises whole egg, egg white or egg yolk. 
     As used herein, the terms “purified” and “isolated” refer to the removal of contaminants from a sample. For example, an enzyme of interest is purified by removal of contaminating proteins and other compounds within a solution or preparation that are not the enzyme of interest. In some embodiments, recombinant enzymes of interest are expressed in bacterial or fungal host cells and these recombinant enzymes of interest are purified by the removal of other host cell constituents; the percent of recombinant enzyme of interest polypeptides is thereby increased in the sample. 
     As used herein, “protein of interest,” refers to a protein (e.g., an enzyme or “enzyme of interest”) which is being analyzed, identified and/or modified. Naturally-occurring, as well as recombinant (e.g., mutant) proteins find use in the present invention. 
     As used herein, “protein” refers to any composition comprised of amino acids and recognized as a protein by those of skill in the art. The terms “protein,” “peptide” and polypeptide are used interchangeably herein. Wherein a peptide is a portion of a protein, those skilled in the art understand the use of the term in context. 
     As used herein, functionally and/or structurally similar proteins are considered to be “related proteins.” In some embodiments, these proteins are derived from a different genus and/or species, including differences between classes of organisms (e.g., a bacterial protein and a fungal protein). In some embodiments, these proteins are derived from a different genus and/or species, including differences between classes of organisms (e.g., a bacterial enzyme and a fungal enzyme). In additional embodiments, related proteins are provided from the same species. Indeed, it is not intended that the present invention be limited to related proteins from any particular source(s). In addition, the term “related proteins” encompasses tertiary structural homologs and primary sequence homologs (e.g., the enzymes of the present invention). In further embodiments, the term encompasses proteins that are immunologically cross-reactive. 
     In some embodiments, the dishwashing detergents of the present invention contain varying concentrations of enzymes.

All percentages and ratios are calculated by weight unless otherwise indicated. All percentages and ratios are calculated based on the total composition unless otherwise indicated. 
     As indicated herein, in some embodiments, the cleaning compositions of the present invention further comprise adjunct materials including, but not limited to, surfactants, builders, bleaches, bleach activators, bleach catalysts, other enzymes, enzyme stabilizing systems, chelants, optical brighteners, soil release polymers, dye transfer agents, dispersants, suds suppressors, dyes, perfumes, colorants, filler salts, hydrotropes, photoactivators, fluorescers, hydrolyzable surfactants, preservatives, anti-oxidants, germicides, fungicides, color speckles, silvercare, anti-tarnish and/or anti-corrosion agents, alkalinity sources, solubilizing agents, carriers, processing aids, pigments, and pH control agents (See e.g., U.S. Pat. Nos. 6,610,642, 6,605,458, 5,705,464, 5,710,115, 5,698,504, 5,695,679, 5,686,014 and 5,646,101, all of which are incorporated herein by reference). Embodiments of specific cleaning composition materials are exemplified in detail below. In embodiments in which the cleaning adjunct materials are not compatible with the cellulases of the present invention in the cleaning compositions, then suitable methods of keeping the cleaning adjunct materials and the cellulase separated (i.e., not in contact with each other) until combination of the two components is appropriate are used. Such separation methods include any suitable method known in the art (e.g., gelcaps, encapsulation, tablets, physical separation, etc.). 
     The cleaning composition of the present invention may be advantageously employed in dishwashing applications, especially automatic dishwashing applications. The compositions of the present invention find use in granular, powder, gel, and liquid compositions, as well as any other suitable format. 
     The compositions of the present invention also find use in cleaning additive products. A cleaning additive product comprising the present invention is ideally suited for inclusion in a wash process when additional bleaching effectiveness is desired. Such instances include, but are not limited to low temperature solution cleaning applications. In some embodiments, the additive is packaged in dosage form for addition to a cleaning process where a source of peroxygen is employed and increased bleaching effectiveness is desired. In some embodiments, the single dosage form comprises a pill, tablet, gelcap or other single dosage unit including pre-measured powders, gels and/or liquids. In some embodiments, filler and/or carrier material(s) are included, in order to increase the volume of such composition. Suitable filler or carrier materials include, but are not limited to, various salts of sulfate, carbonate and silicate as well as talc, clay and the like. In some embodiments filler and/or carrier materials for liquid compositions include water and/or low molecular weight primary and secondary alcohols including polyols and diols. Examples of such alcohols include, but are not limited to, methanol, ethanol, propanol and isopropanol. In some embodiments, the compositions comprise from about 5% to about 90% of such materials. In additional embodiments, acidic fillers are used to reduce the pH of the composition. In some alternative embodiments the cleaning additive includes at least one activated peroxygen source as described below and/or adjunct ingredients as more fully described below. 
     In some preferred embodiments, the cleaning compositions provided herein are typically formulated such that, during use in aqueous cleaning operations, the wash water has a pH of from about 5.0 to about 11.5, or in alternative embodiments, even from about 6.0 to about 10.5. In some preferred embodiments, liquid product formulations are typically formulated to have a neat pH from about 3.0 to about 9.0, while in some alternative embodiments the formulation has a neat pH from about 3 to about 5. In some preferred embodiments, granular products are typically formulated to have a pH from about 8 to about 11. Techniques for controlling pH at recommended usage levels include the use of buffers, alkalis, acids, etc., and are well known to those skilled in the art. 
     In some particularly preferred embodiments, when the cellulose is employed in a granular composition or liquid, the cellulase is in the form of an encapsulated particle to protect the enzyme from other components of the granular composition during storage. In addition, encapsulation also provides a means of controlling the availability of the cellulase during the cleaning process and may enhance performance of the cellulase. It is contemplated that the encapsulated cellulase of the present invention will find use in various settings. It is also intended that the cellulase be encapsulated using any suitable encapsulating material(s) and method(s) known in the art. 
     In some preferred embodiments, the encapsulating material typically encapsulates at least part of the cellulase. In some embodiments, the encapsulating material is water-soluble and/or water-dispersible. In some additional embodiments, the encapsulating material has a glass transition temperature of 0° C. or higher (See e.g., WO 97/11151, particularly from page 6, line 25 to page 7, line 2, for more information regarding glass transition temperatures). 
     In some embodiments, the encapsulating material is selected from the group consisting of carbohydrates, natural or synthetic gums, chitin and chitosan, cellulose and cellulose derivatives, silicates, phosphates, borates, polyvinyl alcohol, polyethylene glycol, paraffin waxes and combinations thereof. In some embodiments in which the encapsulating material is a carbohydrate, it is selected from the group consisting of monosaccharides, oligosaccharides, polysaccharides, and combinations thereof. In some preferred embodiments, the encapsulating material is a starch (See e.g., EP 0 922 499; and U.S. Pat. Nos. 4,977,252, 5,354,559, 5,935,826, for descriptions of some exemplary suitable starches). 
     In some additional embodiments, the encapsulating material comprises a microsphere made from plastic (e.g., thermoplastics, acrylonitrile, methacrylonitrile, polyacrylonitrile, polymethacrylonitrile and mixtures thereof; commercially available microspheres that find use include, but are not limited to EXPANCEL® (Casco Products, Stockholm, Sweden), PM 6545, PM 6550, PM 7220, PM 7228, EXTENDOSPHERES®, and Q-CEL® (PQ Corp., Valley Forge, Pa.), LUXSIL® and SPHERICEL1® (Potters Industries, Inc., Carlstadt, N.J. and Valley Forge, Pa.). 
     The present invention finds use in various geographies where different wash conditions are typically used. For example, different geographies typically have different water hardness. Water hardness is usually described in terms of the grains per gallon mixed Ca 2+ /Mg 2+ . Hardness is a measure of the amount of calcium (Ca 2+ ) and magnesium (Mg 2+ ) in the water. Most water in the United States is hard, but the degree of hardness varies. Moderately hard (60-120 ppm) to hard (121-181 ppm) water has 60 to 181 parts per million (parts per million converted to grains per U.S. gallon is ppm # divided by 17.1 equals grains per gallon) of hardness minerals.

     European water hardness is typically greater than 10.5 (for example 10.5-20.0) grains per gallon mixed Ca 2+ /Mg 2+  (e.g., about 15 grains per gallon mixed Ca 2+ /Mg 2+ ). North American water hardness is typically greater than Japanese water hardness, but less than European water hardness. For example, North American water hardness can be between 3 to 10 grains, 3-8 grains or about 6 grains. Japanese water hardness is typically lower than North American water hardness, usually less than 4, for example 3 grains per gallon mixed Ca 2+ /Mg 2+ .

     Adjunct Materials 
     While not essential for the purposes of the present invention, in some embodiments, the non-limiting list of adjuncts described herein are suitable for use in the cleaning compositions of the present invention. Indeed, in some embodiments, adjuncts are incorporated into the cleaning compositions of the present invention. In some embodiments, adjunct materials assist and/or enhance cleaning performance, treat the substrate to be cleaned, and/or modify the aesthetics of the cleaning composition (e.g., perfumes, colorants, dyes, etc.). It is understood that such adjuncts are in addition to the cellulase of the present invention. The precise nature of these additional components, and levels of incorporation thereof, depends on the physical form of the composition and the nature of the cleaning operation for which it is to be used. Suitable adjunct materials include, but are not limited to, surfactants, builders, chelating agents, dye transfer inhibiting agents, deposition aids, dispersants, additional enzymes, and enzyme stabilizers, catalytic materials, bleach activators, bleach boosters, hydrogen peroxide, sources of hydrogen peroxide, preformed peracids, polymeric dispersing agents, clay soil removal/anti-redeposition agents, brighteners, suds suppressors, dyes, perfumes, structure elasticizing agents, carriers, hydrotropes, processing aids and/or pigments. In addition to those provided explicitly herein, additional examples are known in the art (See e.g., U.S. Pat. Nos. 5,576,282, 6,306,812 and 6,326,348). In some embodiments, the aforementioned adjunct ingredients constitute the balance of the cleaning compositions of the present invention. 
     Surfactants 
     In some embodiments, the cleaning compositions of the present invention comprise at least one surfactant or surfactant system, wherein the surfactant is selected from nonionic surfactants, anionic surfactants, cationic surfactants, ampholytic surfactants, zwitterionic surfactants, semi-polar nonionic surfactants, and mixtures thereof. In some low pH cleaning composition embodiments (e.g., compositions having a neat pH of from about 3 to about 5), the composition typically does not contain alkyl ethoxylated sulfate, as it is believed that such surfactant may be hydrolyzed by such compositions the acidic contents. In some embodiments, the surfactant is present at a level of from about 0.1% to about 60%, while in alternative embodiments the level is from about 1% to about 50%, while in still further embodiments the level is from about 5% to about 40%, by weight of the cleaning composition.

     In some embodiments, the cleaning compositions of the present invention comprise one or more detergent builders or builder systems. In some embodiments incorporating at least one builder, the cleaning compositions comprise at least about 1%, from about 3% to about 60% or even from about 5% to about 40% builder by weight of the cleaning composition. Builders include, but are not limited to, the alkali metal, ammonium and alkanolammonium salts of polyphosphates, alkali metal silicates, alkaline earth and alkali metal carbonates, aluminosilicates, polycarboxylate compounds, ether hydroxypolycarboxylates, copolymers of maleic anhydride with ethylene or vinyl methyl ether, 1,3,5-trihydroxy benzene-2,4,6-trisulphonic acid, and carboxymethyloxysuccinic acid, the various alkali metal, ammonium and substituted ammonium salts of polyacetic acids such as ethylenediamine tetraacetic acid and nitrilotriacetic acid, as well as polycarboxylates such as mellitic acid, succinic acid, citric acid, oxydisuccinic acid, polymaleic acid, benzene 1,3,5-tricarboxylic acid, carboxymethyloxysuccinic acid, MGDA (methyl glycine diacetic acid), glutamic-N-N,diacetic acid, imminosuccinic acid, and soluble salts thereof.

It is contemplated that any suitable builder will find use in the present invention, including those known in the art (See e.g., EP 2 100 949). 
     Chelating Agents 
     In some embodiments, the cleaning compositions of the present invention contain at least one chelating agent. Suitable chelating agents include, but are not limited to copper, iron and/or manganese chelating agents and mixtures thereof. In embodiments in which at least one chelating agent is used, the cleaning compositions of the present invention comprise from about 0.1% to about 15% or even from about 3.0% to about 10% chelating agent by weight of the subject cleaning composition.

     Anti-Redeposition Agents 
     As indicated herein, anti-redeposition agents and/or sulfonated polymers find use in some embodiments of the present invention. In some embodiments, non-ionic surfactants find use. Excellent finishing results are obtained with compositions comprising such compounds alone or in combination. For example, in automatic dishwashing embodiments, non-ionic surfactants find use for surface modification purposes, in particular for sheeting, to avoid filming and spotting and to improve shine. These non-ionic surfactants also find use in preventing the re-deposition of soils. In some preferred embodiments, the anti-redeposition agent is a non-ionic surfactant as known in the art (See e.g., EP 2 100 949). In some embodiments, the non-ionic surfactants have a phase inversion temperature (PIT) in the range of from about 40 to about 70° C. Compositions comprising non-ionic surfactants having a PIT in this temperature range provide very good cleaning. The anti-redeposition agent may also help the enzyme access the soiled substrates. The anti-redeposition agent appears to help with cleaning during the main wash, while some of the agent is carried over to the rinse cycle, where it helps with sheeting, thereby reducing or eliminating sheeting and/or spotting. 
     In some embodiments, the compositions of the present invention reduce the particle size of the soil fragments and/or molecular weight of the soils. This facilitates the suspension of the soils in the wash liquor. Soil suspension can further be improved by an anti-redeposition agent. The anti-redeposition agent contributes by keeping detached soils as individual entities in solution and prevents recombination that can produce grit formation. These agents can also help to detach soils from the soiled surfaces. This, in combination with soil suspension contributes to a more effective enzymatic cleaning and results in better shine and reduced filming and spotting on the washed items. In some embodiments, the anti-redeposition agent(s) are delivered more than once during the dishwashing process. 
     Dye Transfer Inhibiting Agents 
     In some embodiments, the cleaning compositions of the present invention include one or more dye transfer inhibiting agents.

PURADAX® HA400 performance was tested under automatic dishwashing conditions in the presence of commercially available Finish QUANTUM® dishwashing tablets (Reckitt Benckiser), purchased from a local supermarket. The spaghetti/meat/sauce/cheese stain was prepared as described below. Before the soil was applied to the test dishes, the dishes were thoroughly washed. This was particularly necessary in order to remove any remnant residues from previous washings. New dishes were also subjected to three thorough washes before being used for the first time in a test. 
     Preparation of the Spaghetti Mix Stain on Porcelain Plates 
     Pasta sauce (390 g) was mixed with 150 g of boiled spaghetti pasta, 25 g of minced meat (improved IKW composition-a combination of 225 gram fat free minced meat and 75 gram egg yolk) and 50 g of Grozette Formaggio cheese. A spoon was used to spread 3 g of this mixture on each white porcelain plate (Arzberg, 19 cm diameter, white, glazed porcelain, conforming to EN 50242, form 1495, No. 0219) leaving an approximately 2 cm wide unsoiled margin around the rim. The plates were dried by baking them for 2 hours at 120° C. in an oven. As soon as the plates were cooled, they were ready for use. The plates were stacked with paper towels between each of the plates for storage. 
     Washing Equipment and Conditions 
     The washing tests were performed in an automatic dishwasher (Miele G6382SCplus) and the soiled dishes prepared as described above. A defined amount of detergent (20 gram or 1 tablet) was used with or without 5% (w/w) PURADAX® HA400. The temperature for the washing conditions was 50° C. The water hardness was 9 GH. Cycle time was 60 minutes, with the main wash cycle time of 20 minutes. A total of 33 plates were assessed in 9 wash cycles. 
     After washing, the plates were sprayed with iodine solution (0.05N) for better identification of the carbohydrate residues. Evaluation of the washing performance was done by visually inspecting the color reactions of the carbohydrate residues with reference to the IKW photographic catalogue (IKW) and rated on a scale of 0-10 (10 being clean). Results are shown in Table 1. In this Table, “Rating” refers to the rating on the photographic catalogue (IKW). As indicated, PURADAX® HA400 cellulase shows cleaning benefits on this spaghetti/meat/sauce/cheese stain.
