摘要:
A process for expressing extracellular .beta.-glucosidase in a filamentous fungus by expressing a fungal DNA sequence encoding enhanced, deleted or altered .beta.-glucosidase in a recombinant host microorganism is disclosed. Recombinant fungal cellulase compositions containing enhanced, deleted or altered expression of .beta.-glucosidase is also disclosed.

摘要:
A method and media for producing bacterial cellulose under agitated culture conditions resulting in sustained production over an average of 70 hours of at least 0.1 g/liter per hour are achieved. A unique reticulated cellulose product is produced using the methods and conditions claimed, and may be converted to of a sheet characterized by substantial resistance to densification and great tensile strength when produced by sheet forming means. Acetobacter strains are identified as stable under agitated culture conditions and exhibit substantially reduced gluconic and keto-gluconic acids production.

摘要:
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.
