摘要:
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.

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.

The present invention relates to the co-expression and production of a heterologous alpha amylase and an endogenous glucoamylase in an Aspergillus strain and enzyme compositions including the same.
摘要:
DNA is provided which encodes an enzyme having phytase activity isolated from Penicillium, Fusarium, Humicola and Emericella. Also provided for is a method of isolating DNA encoding an enzyme having phytase activity from organisms which possess such DNA, transformation of the DNA into a suitable host organism, expression of the transformed DNA and the use of the expressed phytase protein in feed as a supplement.
摘要:
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.; (iv) a molecular weight of about 50,000 daltons, a pI of about 5.8, and a maximum activity at pH 7.5 at a temperature of about 65.degree. C.; and (v) a molecular weight of about 35,000 daltons, a pI of about 5.3, and a maximum activity at pH 7.5 at a temperature of about 70.degree. C.
摘要:
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.
摘要:
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 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.
