  • Cellulase preparation comprising an endoglucanase enzyme
    Patent number: 5948672
    Abstract: A cellulase preparation consisting essentially of a homogeneous endoglucanase component which is immunoreactive with an antibody raised against a highly purified .about.43 kD endoglucanase derived from Humicola insolens, DSM 1800, or which is homogeneous to said .about.43 kD endoglucanase, may be employed in the treatment cellulose-containing fabrics for harshness reduction or color clarification or to provide a localized variation in the color of such fabrics, or it may be employed in the treatment of paper pulp.

  • Detergent compositions containing protease and novel inhibitors for use therein
    Patent number: 5674833
    Abstract: A detergent composition and additive comprising a protease and a reversible protease inhibitor of the peptide or protein type, wherein the ratio of the dissociation constant to the protease concentration in the range from 0.006 to 6. When the protease is subtilisin, the protease inhibitor is preferably a modified subtilisin inhibitor of Family VI.
