Abstract: Disclosed are improved methods for treating cotton-containing fabrics as well as the fabrics produced from these methods. In particular, the disclosed methods are directed to contacting cotton-containing fabrics with an aqueous solution containing a fungal cellulase composition which comprises one or more EG type components and one or more CBH I type components wherein said cellulase composition has a protein weight ratio of all EG type components to all CBH I type components of greater than 5:1. Cotton-containing fabrics so treated possess decreased strength loss as compared to fabrics treated with a cellulase composition containing greater amounts of CBH I type components.

Abstract: Disclosed are improved aqueous processes and compositions for obtaining a "stonewashed", look in colored fabric while reducing the amount of redeposition of colorant onto the fabric, as well as the fabrics produced from these methods. In particular, the disclosed methods as directed to contacting fabrics with fungal cellulase composition which is substantially free of CBH type components. Fabrics so treated show reduced redeposition of colorant.

Abstract: An enzyme feed additive is provided comprising a xylanase, a protease, and optionally a .beta.-glucanase. The ratio of the units of xylanase activity per unit amount of the feed additive to the units of .beta.-glucanase activity per same unit amount of the feed additive is 1:0-0.25.Preferably, the xylanase is the low pI xylanase and/or the high pI xylanase obtained from Trichoderma longibrachiatum.Preferably, the protease is a mutant subtilisin comprising a substitution at the amino acid residue position equivalent to tyr+217 of Bacillus amyloliquefaciens subtilisin with leucine.

Abstract: Disclosed are improved methods for treating cotton-containing fabrics and non-cotton containing cellulosic fabrics as well as the fabrics produced from these methods. In particular, the disclosed methods are directed to contacting cotton-containing fabrics and non-cotton containing cellulosic fabrics with a cellulase solution containing a fungal cellulase composition which is substantially free of all CBH I type cellulase components. Cotton-containing fabrics so treated possess decreased strength loss as compared to fabrics treated with a cellulase solution containing a complete cellulase composition.

Abstract: The present invention is directed to purified EG III cellulase enzyme isolated from Trichoderma longibrachiatum and the amino acid sequence of the secreted (mature) and non-secreted (preprotein) forms. The present invention is further directed to the DNA fragment and sequence that encodes the EG III cellulase enzyme. Also disclosed are methods for isolating either purified or highly enriched EG III cellulase obtained from Trichoderma spp. or genetically modified strains of Trichoderma spp.

Abstract: Disclosed are detergent compositions containing a cleaning effective amount of a surfactant or a mixture of surfactants and from about 0.01 to about 5 weight percent of substantially pure EG III cellulase. Preferably, the detergent composition contains no more than about 5 weight percent of CBH I type components based on the total weight of cellulase proteins. When employed in aqueous wash media, the detergent compositions impart color retention/restoration properties to cotton-containing fabrics.

Abstract: Disclosed are methods for enhancing the quality of printing on cotton-containing fabrics. Specifically, this methods disclosed herein recite the pretreatment of cotton-containing fabrics with cellulase prior to printing in order to enhance printing characteristics on the fabric such as pigment uptake, enhanced clarity, reduced pigment bleeding, and the like. The methods disclosed herein generally entail treating cotton-containing fabrics with an aqueous cellulase formulation and preferably with an aqueous cellulase solution under agitating conditions.

Abstract: Methods for isolating EG III cellulase component and enriched EG III cellulase in polyethylene glycol are disclosed. The methods comprise adding an inorganic salt and polyethylene glycol having a molecular weight of from about 5,000 to 10,000 to an aqueous mixture of cellulase proteins under conditions to create a two-phase system. Next, the cellulase proteins other than EG III are separated in an EG III-poor aqueous phase while EG III cellulase component is retained in an EG III-rich polyethylene glycol phase. Lastly, the EG III component can be separated from the polyethylene glycol. The preferred method of separation is alcohol precipitation.

Abstract: Disclosed are detergent compositions containing a combination of exo-cellobiohydrolase I type cellulase components and endoglucanase components wherein the exo-cellobiohydrolase I type cellulase components are enriched relative to the endoglucanase components. The detergent compositions of this invention provide excellent cleaning of cotton garments while also providing substantially reduced degradation of the cotton fabric in the garment.
