Assignee:

CP Kelco U.S., Inc. - Wilmington DE

International Classification:

C12N 100

US Classification:

4352521, 435101, 435243, 435823, 536 56

Abstract:

Acetobacter strains are identified as stable under agitated culture conditions and exhibit substantially reduced gluconic and keto-gluconic acids production. 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. Preferred Acetobacter strains are ATCC Nos. 53264, 53263 and 53524.

US Classification:

435101

Abstract:

A method and media are provided 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 in the form of a sheet characterized by substantial resistance to densification and great tensile strength when produced by sheet forming means. Strains of Acetobacter that are stable under agitated culture conditions and that exhibit substantially reduced gluconic and keto-gluconic acids production are described.

Assignee:

Genencor International, Inc. - Palo Alto CA

International Classification:

C11D 3386

US Classification:

510321

Abstract:

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.
