Patent number: 6528293Abstract: A method is disclosed for activating a lipase by adding a solution of lipase in an aqueous buffer at a pH near neutrality to an organic phase, e.g., tetradecane. Under these conditions lipase is activated as a function of an organic-and-water boundary surface between the organic and water phases.

Patent number: 6427933Abstract: The main theme of the invention is to provide a method for manufacturing industrially, by mechanically comminuting silk yarn, crystalline silk fibroin powder below 3 &mgr;m in an average particle diameter, which can be used for various applications. A silk substance such as cocoon filament, silk yarn, or raw silk is brought into an alkali aqueous solution under a pressure of 1 through 5 atmospheric pressure at temperatures from 100° C. through 150° C. to reduce the tensile strength of the silk substance to around 0.02 g/d or less. Thereafter, the resultant silk substance is subjected to dealkalization and drying. Subsequently, the resultant dried silk substance is comminuted into powder below 3 &mgr;m in an average particle diameter. Thus, the crystalline silk fibroin powder below 3 &mgr;m in an average particle diameter is manufactured.Type: GrantFiled: March 28, 2000Date of Patent: August 6, 2002Assignees: Japan as represented by Director General of National Institute of Sericultural and Entomological Science Ministry of Agriculture, Forestry and Fisheries, National Institute of Agrobiological SciencesInventor: Kozo Tsubouchi
