Abstract: Textile fibers are treated with enzymes in the absence of surfactants, with the effect of increasing the wettability and absorbency of the fibers. The enzymes are pectinases, cellulases, proteases, lipases or combinations thereof. The wetting properties of cotton fibers are found to be most substantially improved by treatment with a mixture of cellulase and pectinase. The effects of five hydrolyzing enzymes on improving the hydrophilicity of several polyester fabrics have been studied. Four out of the five lipases studied improve the water wetting and absorbent properties of the regular polyester fabrics more than alkaline hydrolysis under optimal conditions (3N NaOH at 55° C. for 2 hours). Compared to aqueous hydrolysis, the enzyme reactions have shown to be effective under more moderate conditions, including a relatively low concentration (0.01 g/L), a shorter reaction time (10 minutes), at an ambient temperature (25° C.).

Abstract: 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.

Abstract: Disclosed are cellulase compositions containing one or more endoglucanase components and less than about 5 weight percent of CBH I type components. When incorporated into detergent compositions and used in acidic, neutral, or alkaline washing media, such cellulase compositions impart color retention/restoration properties as well as improved softening properties to cotton-containing fabrics. Additionally, such compositions impart reduced strength loss to cotton-containing fabrics as compared to cellulase compositions containing greater amounts of CBH I type components.

Abstract: A feed additive that provides increased feed conversion ratio is prepared containing a physiologically acceptable carrier and one or more of five thermostable xylanases from Microtetraspora flexuosa, preferably strain ATCC 35864. The xylanases can tolerate heating for one minute in a water bath at 95.degree. C. without substantial loss of activity, and tolerate alkaline conditions in a pH range of 7.0-10.0. A feed for poultry or pigs contains the xylanases in a feed containing at least 20% by weight cereal. The five xylanases have the following characteristics: (i) a molecular weight of about 33,100 daltons, a pI of about 8.5, and a maximum activity at pH 7.0-7.5 at a temperature of about 70.degree. C.; (ii) a molecular weight of about 33,300 daltons, a pI of about 7.5, and a maximum activity at pH 7.0-7.5 at a temperature of about 65.degree. C.; (iii) a molecular weight of about 31,000 daltons, a pI of about 6.2, and a maximum activity at pH 7.5 at a temperature of about 65.degree. C.
