Title:
LIQUEFYING ALKALINE alpha-AMYLASE, PROCESS FOR PRODUCING THE SAME, AND DETERGENT COMPOSITION CONTAINING THE SAME
Document Type and Number:
WIPO Patent Application WO/1994/026881
Kind Code:
A1
Abstract:
A liquefying alkaline alpha-amylase having the following enzymological properties: (1) action: this enzyme hydrolyzes alpha-1,4-glycoside linkages of starch, amylose, amylopectin and partial hydrolyzates thereof, and forms glucose, maltose, maltotriose, maltotetraose, maltopentaose and maltohexaose from amylose, though it does not act upon pullulan; (2) isoelectric point: it has an isolectric point exceeding 8.5 as measured by isoelectric electrophoresis. This enzyme has such a liquefying activity as to hydrolyze starch and starch polysaccharides at high random and has an optimum pH value on an alkaline side. Since it has a high isoelectric point, it can readily be purified. A detergent composition containing this enzyme has an excellent detergency against especially stains due to spilt food.
