During the desizing and enzymatic stonewashing of denim fabric and/or garments, redeposition of blue color often occurs back onto the surfaces of the denim. The invention relates to a redepositing or backstain inhibiting composition and a method requiring the inclusion of an added protease prior to, during or subsequent to the stonewashing process which reduces the redeposition of the blue dye and hence improves the stonewashing process when using redepositing or backstaining cellulases to give an appearance closer to that when using stones alone or nonredepositing cellulases in the stonewashing process.

Enzymatic compositions and methods for producing stonewashed look on indigo-dyed denim fabric and garments

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

Degradation resistant detergent compositions based on cellulase enzymes

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 CBH I type components and one or more EG type components wherein said cellulase composition has a protein weight ratio of CBH I type components to all EG type components of greater than 10:1. Cotton-containing fabrics so treated possess decreased strength loss as compared to fabrics treated with a complete cellulase composition.

Methods for treating cotton-containing fabrics with CBH I enriched

A cleaning composition is disclosed. The composition contains a first enzyme where the enzyme can be Endo-D, Endo-H, Endo-L, Endo-C, Endo-CII, Endo-F-Gal type, Endo-F and PNGaseF and a second enzyme where the enzyme can be a protease, lipase, nuclease, glycosidase, an enzyme different from the first enzyme, and any combination of these. The composition also contains a detergent surfactant and a builder. The composition can be used in a method for cleaning a surface on which is bound a glycoside-containing substance. The substance can be blood or components thereof, fecal matter or components thereof or microorganisms. The surface can be fabric, biological tissue, tooth enamel, contact lens, glass, ceramic, metal, metal alloy, plastic, plant, fruit and vegetable.

Cleaning composition containing a type II endoglycosidase

An antimicrobial composition consisting essentially of from about 1 ppm to about 1200 ppm of a Type II endoglycosidase and from about 0.5 ppm to about 1200 ppm of an antimicrobial agent is disclosed. The preferred Type II endoglycosidases to be used in the invention are Endo-D, Endo-H, Endo-F and PNGaseF. The preferred antimicrobial agents are bactericides, fungicides and algicides. The composition can be used in the form of personal care or household cleaning products such as liquid soap, hard surface cleaner, laundry detergent, anti-acne medication, deodorant, shampoo, face cream, mouthwash, dentifrice and denture cleaner.

Antimicrobial composition containing Type II endoglycosidase and

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.

Methods of enhancing printing quality of pigment compositions onto

Microorganisms are removed from the surface of materials such as fabrics or contact lenses by treatment with a Type II endoglycosidase. The Type II endoglycosidase may be used alone or in combination with other enzymes, detergents, surfactants and/or disulfide cleaving reagents to facilitate removal of the microorganisms. The Type II endoglycosidase may be an Endo-.beta.-N-acetylglucosaminidase, Endo-.alpha.-N-acetylgalactosaminidase or Endo-.beta.-N-galactosidase.

Method of removing microorganisms from surfaces with Type II

A method for cleaning a surface on which is bound a glycoside-containing substance. The substance can be blood or components thereof, fecal matter or components thereof or microorganisms. The surface can be fabric, biological tissue, tooth enamel, contact lens, glass, ceramic, metal, metal alloy, plastic, plant, fruit and vegetable. A Type II endoglycosidase is used to carry out the method.

Method for cleaning a surface on which is bound a glycoside-containing

A method of improving dough characteristics is provided which includes the steps of mixing dough with a Type II endoglycosidase to form a dough mixture, shaping the dough mixture, and baking the said shaped dough mixture to form a baked good. The method of the present invention preferably uses endoglycosidase H mixed with bread dough which imparts better make-up performance of the dough, superior crumb qualities, softness of bread and higher loaf volumes.

Type II endoglycosidases in baking for improving the quality of dough

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.

Contact lens cleaning compositions and a method which comprises treating soft contact lenses with general purpose proteases in combination with endoproteinase lys-C are effective in dissolving away and hydrolyzing lysozyme, the major protein component of tears.
