ABSTRACT:
A cellulase preparation useful for reducing the harshness of cotton-containing fabrics and for reducing the rate at which such fabrics become harsh comprises about 40% or more (based on the total protein content) of an endoglucanase component with a pH optimum of about 7.5-10.0 with a high CMC-endoase activity and affinity towards cellulose and essentially no cellobiohydrolase activity. The cellulase composition is endogenous to a strain of Humicola, Myceliophthora, or Fusarium. A method for the recombinant production of said cellulase preparation is provided.
