     Physico-Chemical Properties 
     In preferred embodiments, the lipolytic enzyme of the invention may be characterized by having one or more of the following physico-chemical properties. 
     The enzyme has a pH optimum in the range of from about 7 to about pH 9, more specifically around pH 8, when determined at 30° C. with tributyrine as substrate. 
     The enzyme has the following N-terminal amino acid sequence (cf. SEQ ID NO:1): 
     
         Ala--Val--Ser--Val--Ser--Thr--Thr--Asp--Phe--Gly--Asn--Phe--Lys--Phe--Tyr--Ile--Gln--His--Gly--Ala--Ala--Ala--Tyr--Xaa--Asn-- 
    
     The enzyme has a molecular weight of 28.4 kDa, as determined by mass spectrometry. 
     Immunochemical Properties 
     In another preferred embodiment, the lipolytic enzyme of the invention is characterized by having having immunochemical properties identical or partially identical (i.e. at least partially identical) to those of a lipase obtained from the strain Fusarium culmorum CBS 513.94. 
     The immunochemical properties can be determined by immunological cross-reaction identity tests. The identity tests can be performed by the well-known Ouchterlony double immunodiffusion procedure or by tandem crossed immunoelectrophoresis according to I. M. Roitt; Immunology, Gower Medical Publishing (1985) or N. H. Axelsen; Handbook of Immunoprecipitation-in-Gel Techniques; Blackwell Scientific Publications (1983), chapters 5 and 14. The terms &#34;immunochemical identity&#34; (antigenic identity) and &#34;partial immunochemical identity&#34; (partial antigenic identity) are described in Axelsen, supra, chapters 5, 19 and 20, and in I. M. Roitt, supra, Chapter 6. 
     Monospecific antiserum for use in immunological tests can be raised, e.g. in rabbits, against the purified lipase of the invention, e.g. as described in Chapter 41 of N. H. Axelsen, supra, or Chapter 23 of N. H. Axelsen et al., A Manual of Quantitative Immunoelectrophoresis, Blackwell Scientific Publications (1973). 
     Preparation of the Lipolytic Enzyme 
     The lipolytic enzyme of the invention may be produced by cultivation of a strain of Fusarium culmorum in a suitable nutrient medium, containing carbon and nitrogen sources and inorganic salts, followed by recovery of the lipase. In a preferred embodiment, the lipase producing strain is the strain Fusarium culmorum CBS 513.94, or a mutant or a variant thereof. 
     The lipolytic enzyme may also be obtained by recombinant DNA-technology by methods known in the art per se, e.g. isolating a DNA fragment encoding the lipase, combining the DNA fragment with appropriate expression signal(s) in an appropriate vector, introducing the vector or parts thereof into an appropriate host, either as an autonomously replicating plasmid or integrated into the chromosome, cultivating the host organism under conditions leading to expression of the lipase, and recovering the lipase from the culture medium. 
     In preferred embodiments of the invention, the host organism is of bacterial origin, preferably a strain of Escherichia coli, or a strain of Bacillus, or a strain of Streptomyces, or of fungal origin, preferably a strain of Aspergillus, a strain of Neurospora, a strain of Fusarium, or a strain of Trichoderma, or a yeast cell, preferably a strain of Saccharomyces, or a strain of Kluyveromyces, or a strain of Hansenula, or a strain of Pichia. 
     After the cultivation, the lipolytic enzyme may be recovered and purified from the culture broth by conventional methods, such as hydrophobic chromatography, ion exchange chromatography or combinations thereof. 
     Lipolytic Activity 
     The lipolytic activity may be determined using tributyrine as substrate. This method is based on the hydrolysis of tributyrin by the enzyme, and the alkali consumption is registered as a function of time. 
     One Lipase Unit (LU) is defined as the amount of enzyme which, under is standard conditions (i.e. at 30.0° C.; pH 7.0; and tributyrine as substrate) liberates 1 μmol titratable butyric acid per minute. Gum Arabic is used as emulsifier. 
     A folder AF 95/5 describing this analytical method in more detail is available upon request to Novo Nordisk A/S, Denmark, which folder is hereby included by reference. 
     Detergent Compositions 
     The lipolytic enzyme of the invention may typically be a component of a detergent composition. As such, it may be included in the detergent composition in the form of a non-dusting granulate, a stabilized liquid, or a protected enzyme. Non-dusting granulates may be produced, e.g., as disclosed in U.S. Pat. Nos. 4,106,991 and 4,661,452 (both to Novo Industri A/S) and may optionally be coated by methods known in the art. Examples of waxy coating materials are poly(ethylene oxide) products (polyethyleneglycol, PEG) with mean molecular weights of 1000 to 20000; ethoxylated nonylphenols having from 16 to 50 ethylene oxide units; ethoxylated fatty alcohols in which the alcohol contains from 12 to 20 carbon atoms and in which there are 15 to 80 ethylene oxide units; fatty alcohols; fatty acids; and mono- and di- and triglycerides of fatty acids. Examples of film-forming coating materials suitable for application by fluid bed techniques are given in patent GB 1483591. Liquid enzyme preparations may, for instance, be stabilized by adding a polyol such as propylene glycol, a sugar or sugar alcohol, lactic acid or boric acid according to established methods. Other enzyme stabilizers are well known in the art. Protected enzymes may be prepared according to the method disclosed in EP 238,216. 
     The detergent composition of the invention may be in any convenient form, e.g. as powder, granules, paste or liquid. A liquid detergent may be aqueous, typically containing up to 70% water and 0-30% organic solvent, or nonaqueous. 
     The detergent composition comprises one or more surfactants, each of which may be anionic, nonionic, cationic, or zwitterionic. The detergent will usually contain 0-50% of anionic surfactant such as linear alkylbenzenesulfonate (LAS), alpha-olefinsulfonate (AOS), alkyl sulfate (fatty alcohol sulfate) (AS), alcohol ethoxysulfate (AEOS or AES), secondary alkanesulfonates (SAS), alpha-sulfo fatty acid methyl esters, alkyl- or alkenylsuccinic acid, or soap. It may also contain 0-40% of nonionic surfactant such as alcohol ethoxylate (AEO or AE), carboxylated alcohol ethoxylates, nonylphenol ethoxylate, alkylpolyglycoside, alkyldimethylamine oxide, ethoxylated fatty acid monoethanolamide, fatty acid monoethanolamide, or polyhydroxy alkyl fatty acid amide (e.g. as described in WO 92/06154). 
     The detergent composition may additionally comprise one or more other enzymes conventionally used in detergent compositions, such as an amylase, a cutinase, a protease, a cellulase, a peroxidiase, and/or an oxidase. 
     The detergent may contain 1-65% of a detergent builder or complexing agent such as zeolite, diphosphate, triphosphate, phosphonate, citrate, nitrilotriacetic acid (NTA), ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DTMPA), alkyl- or alkenylsuccinic acid, soluble silicates or layered silicates (e.g. SKS-6 from Hoechst). The detergent may also be unbuilt, i.e. essentially free of detergent builder. 
     The detergent may comprise one or more polymers. Examples are carboxymethylcellulose (CMC), poly(vinylpyrrolidone) (PVP), polyethyleneglycol (PEG), poly(vinyl alcohol) (PVA), polycarboxylates such as polyacrylates, maleic/acrylic acid copolymers and lauryl methacrylate/acrylic acid copolymers. 
     The detergent may contain a bleaching system which may comprise a H 2  O 2  source such as perborate or percarbonate which may be combined with a peracid-forming bleach activator such as tetraacetylethylenediamine (TAED) or nonanoyloxybenzenesulfonate (NOBS). Alternatively, the bleaching system may comprise peroxyacids of, e.g., the amide, imide, or sulfone type. 
     The enzymes of the detergent composition of the invention may be stabilized using conventional stabilizing agents, e.g. a polyol such as propylene glycol or glycerol, a sugar or sugar alcohol, lactic acid, boric acid, or a boric acid derivative such as, e.g., an aromatic borate ester, and the composition may be formulated as described in, e.g., WO 92/19709 and WO 92/19708. 
     The detergent may also contain other conventional detergent ingredients such as, e.g., fabric conditioners including clays, foam boosters, suds suppressors, anti-corrosion agents, soil-suspending agents, anti-soil-redeposition agents, dyes, bactericides, optical brighteners, or perfume. 
     The pH (measured in aqueous solution at use concentration) will usually be neutral or alkaline, e.g. in the range of 7-11.

     EXAMPLES 
     The invention is further illustrated with reference to the following examples which are not intended to be in any way limiting to the scope of the invention as claimed. 
     Example 1 
     Cultivation Example 
     Seed cultures of the strain Fusarium culmorum CBS 513.94 were produced in 500 ml shakeflasks containing 100 ml of the following composition: 
     Corn steep liquer (dried) 12 g/l 
     Glucose 24 g/l 
     To each flask is added 0.5 g CaCO 3  and 0.5 ml of oil. 
     pH is adjusted to 5.5 before autoclavation. 
     After 3 days at 26° C. and 250 rpm, 5 ml of each of the seed cultures were inoculated in shakeflasks containing 100 ml of the following medium: 
     Pepton, Difco 0118 6 g/l 
     Pepticase, Sheffield Products 4 g/l 
     Yeast extract, Difco 0127 3 g/l 
     Meat extract, Difco 0126 1.5 g/l 
     Dextrose, Roquette 101-0441 1 g/l 
     Olive oil, Sigma 10 g/l 
     pH is adjusted to 7.3-7.4 before autoclavation. 
     Cultivation took place for 9 days at 26° C. and 250 rpm. The broths were centrifuged and the supernatants purified on a hydrophobic matrix (TSK gel Butyl-ToyoPearl 650 C column, available from Tosoh Corporation, Japan), and applied for further studies. 
     Example 2 
     Characterization Example 
     pH Optimum 
     The supernatant obtained according to Example 1 was subjected to the LU method for determining lipase activity described above, and the relation between pH and lipase activity of the lipolytic enzyme of the invention was determined at 30° C. in the range of from pH 6 to pH 10. 
     The results of this characterization is presented in FIG. 1. The lipolytic enzyme has its pH optimum in the range of from about pH 7 to about pH 9, more specifically around pH 8. 
     Molecular Weight Determination 
     Mass spectrometry was done using matrix assisted laser desorption ionisation time-of flight (MALDI-TOF) mass spectrometry in a VG Analytical TofSpec. For mass spectrometry, 2 μl of sample obtained according to Example 1 were mixed with 2 μl saturated matrix solution (α-cyano-4-hydroxycinnamic acid in 0.1% TFA:acetonitrile (70:30)), and 2 μl of the mixture spotted onto the target plate. Before introduction into the mass spectrometer the solvent was removed by evaporation. The sample was desorbed and ionised by 4 ns laser pulses (337 nm) at threshold laser power and accelerated into the field-free flight tube by an accelerating voltage of 25 kV. Ions were detected by a micro channel plate set at 1850 V. The spectra were calibrated externally with proteins of known mass. 
     A mass of 28.4 kDa was determined. 
     N-terminal Amino Acid Sequence 
     Using standard methods for obtaining and sequencing peptides  Findlay &amp; Geisow (Eds.) (1989); Protein sequencing--a practical approach; IRL Press!, the following 25 N-terminal amino acid residues of the lipolytic enzyme have been identified, as presented by SEQ ID NO:1 (where Xaa designates an unknown amino acid residue): 
     
         Ala--Val--Ser--Val--Ser--Thr--Thr--Asp--Phe--Gly--Asn--Phe--Lys--Phe--Tyr--Ile--Gln--His--Gly--Ala--Ala--Ala--Tyr--Xaa--Asn-- 
    
     Example 3 
     Lipolytic Activity 
     Using a monolayer equipment (KSV-5000, KSV Instruments, Finland) it has been demonstrated that the lipolytic enzyme from Fusarium culmorum has considerably increased activity towards dicaprin in presence of long chained alcoholethoxylates. 
     A mixed monolayer in a well defined overall composition, made of a diglyceride substrate and a monocomponent alcoholethoxylate (AEO: Heptaethylene glycol monooctadecyl ether) is spread on an aqueous subphase (10 mM Glycine, pH 10.0, 0.1 mM EDTA, 25° C.). The surface pressure is adjusted to the desired value, and a well-defined amount of enzyme (10 LU; lipase units as defined above) is injected into the subphase. Lipolytic action is manifested through the speed of a mobile barrier compressing the monolayer in order to maintain constant surface pressure as insoluble substrate molecules are hydrolysed into more water soluble reaction products. Using this assay, lipolytic enzymes are discriminated by a parameter β indicating the final area-fraction of substrate (dicaprin) left unhydrolysed by the enzyme as lipolytic activity stops. 
     In this way, the lipase of the invention was compared to an Aspergillus lipase conventionally used in detergents (Lipolase™, available from Novo Nordisk A/S, Denmark). The results are presented in Table 1, below.

     These results show that when compared to Lipolase™, the lipolytic enzyme obtained from Fusarium culmorum is considerably more efficient when alcoholethoxylates are present in the substrate phase. 
     Example 4 
     Substrate Affinity 
     A procedure has been developed aiming at a simple comparison of the ability of lipolytic enzymes to accumulate on/in a substrate phase (olive oil) at alkaline pH (pH 9.0) and presence of the non-ionic surfactant Dobanol 25-7 (2500 ppm) in the aqueous phase. 
     Procedure 
     1. Two identical buffer solutions (5 ml) are prepared in 20 ml sealable vials, (&#34;Sample&#34; (s) and &#34;Reference&#34; (r)). 
     2. Enzyme is added into &#34;Sample&#34; and &#34;Reference&#34; and the lipase concentration is determined (X LU/ml). 
     3. Olive oil is added onto the &#34;Sample&#34; and both lipase solutions are shaken vigorously. Incubation at 4° C. over night. 
     4. Remaining lipase concentration in the aqueous phases is determined after incubation (Y 1  LU/mi; i=r,s). 
     Summary of Incubation Conditions 
     Buffer 100 mM Glycine (5 ml). 
     pH 9.0. 
     Substrate Olive oil (5 ml). 
     Temperature 4° C. 
     Lipase activity 5-10 LU/ml. 
     Incubation Over night (24-26 hours). 
     Evaluation of Data 
     The result is calculated by comparing the activity-loss upon incubation in the aqueous phase in contact with olive oil to the activity-loss in the aqueous phase in absence of olive oil:
