Patent number: 6066494Abstract: Textile fibers are treated with enzymes in the absence of surfactants, with the effect of increasing the wettability and absorbency of the fibers. The enzymes are pectinases, cellulases, proteases, lipases or combinations thereof. The wetting properties of cotton fibers are found to be most substantially improved by treatment with a mixture of cellulase and pectinase. The effects of five hydrolyzing enzymes on improving the hydrophilicity of several polyester fabrics have been studied. Four out of the five lipases studied improve the water wetting and absorbent properties of the regular polyester fabrics more than alkaline hydrolysis under optimal conditions (3N NaOH at 55.degree. C. for 2 hours). Compared to aqueous hydrolysis, the enzyme reactions have shown to be effective under more moderate conditions, including a relatively low concentration (0.01 g/L), a shorter reaction time (10 minutes), at an ambient temperature (25.degree. C.).Type: GrantFiled: March 16, 1998Date of Patent: May 23, 2000Assignee: The Regents of the University of CaliforniaInventors: You-lo Hsieh, Mary Michelle Hartzell, Matthew G. Boston, Kathleen A.

Patent number: 5780422Abstract: Bacteria which produce large amounts of a cellulase-containing cell-free fermentate have been identified. The original bacterium (ATCC 55703) was genetically altered using nitrosoguanidine (MNNG) treatment to produce the enhanced cellulase producing bacterium (ATCC 55702), which was identified through replicate plating. ATCC 55702 has improved characteristics and qualities for the degradation of cellulosic waste materials for fuel production, food processing, textile processing, and other industrial applications. ATCC 55702 is an improved bacterial host for genetic manipulations using recombinant DNA techniques, and is less likely to destroy genetic manipulations using standard mutagenesis techniques.Type: GrantFiled: October 8, 1996Date of Patent: July 14, 1998Assignee: Lockheed Martin Energy Systems, Inc.Inventor: H. Craig Dees

Patent number: 5769900Abstract: Mixtures of various starch-degrading enzymes (amylases) which comprise at least one high temperature amylase (HTA) and at least one low temperature amylase (LTA) in an activity ratio of HTA to LTA of 10%:90% to 90%:10% develop at least 60% of their maximum activity in the temperature range from 30.degree. to 90.degree. C. Such mixtures can be diluted with water and treated with customary additives. These mixtures are suitable for desizing textiles sized with starch by treatment of the textiles with the mixtures mentioned and subsequent rinsing.Type: GrantFiled: January 22, 1997Date of Patent: June 23, 1998Assignees: Bayer Aktiengesellschaft, Genencor International GmbHInventors: Wilfried Hahn, Axel Seitz, Martin Riegels, Rainhard Koch, Michael Pirkotsch
