  • Fungal cellulase composition containing alkaline CMC-endoglucanase and essentially no cellobiohydrolase and method of making thereof
    Patent number: 5776757
    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.
    Type: Grant

  • Methods for reducing the harshness of a cotton-containing fabric
    Patent number: 5648263
    Abstract: The present invention relates to methods of reducing the rate at which a cotton-containing fabric becomes harsh or of reducing the harshness of a cotton-containing fabric, comprising treating the cotton-containing fabric with a cellulase preparation obtained from a fungus, wherein the cellulase preparation comprises a substantially homogeneous endoglucanase component which: (a) has a pH optimum of about 7.5-10.0; (b) exhibits a CMC endoase activity of at least about 10 CMC-endoase units per mg of total protein; (c) exhibits a CAVU activity of at least about 50% at a pH of 7.0-12.0; and (d) has essentially no cellobiohydrolase activity; wherein at least about 50% by weight of the total cellulase content of the cellulase preparation is the endoglucanase component.
