Abstract: A liquefying alkaline α-amylase having the following enzymological properties: (1) action: this enzyme hydrolyzes α-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.

Abstract: The present invention relates to a novel enzyme called alkaline proteinase K-16 that is characterized as having an optimum pH in an alkaline range, and stability in the presence of various surface active agents, such as sodium linear alkylbenzene sulfonate, sodium polyoxyethylene alkyl sulfate, sodium dodecyl sulfate, sodium alpha -olefin sulfonate, sodium alkyl sulfonate, and alpha -sulfo-fatty acid ester. The present invention further provides for a microorganism producing the novel alkaline proteinase, and a process for producing the novel alkaline proteinase. Alkaline proteinase K-16 of the present invention exhibits an excellent action against insoluble proteins and maintains sufficient activity over a wide temperature range and in the presence of surface active agents thus providing a use as an enzyme for detergents.

Abstract: A novel alkaline cellulase is disclosed. The alkaline cellulase is produced by Bacillus sp KSM-635 (FERM BP-1485) and possesses: (1) Cx enzyme activity to act on carboxymethyl cellulose and weak C1 enzyme and beta -glucosidase activities, (2) substrate specificity to act on carboxymethyl cellulose, cellulose cotton, Avicel, filter paper, cellobiose, and p-nitrophenyl cellobioside, (3) a working pH range of 4-12 and an optimum pH range of 9-10, (4) stable pH range of 4.5-10.5 when allowed to stand at 40 DEG C for 10 minutes, and (5) working temperature range of 10-65 DEG C and optimum temperature range at around 40 DEG C. Its activity is not inhibited by chelating agents nor by surface active agents. It is particularly effective as an additive for laundry detergent compositions.

Abstract: Alkaline cellulases having an optimum pH in an alkaline range and being stable over a broad pH range are produced by microorganisms which belong to the genus Bacillus and grow in a neutral medium. These alkaline cellulases are rarely inhibited by ingredients ordinarily incorporated in detergents such as surface active agents, proteinases and chelating agents, so that they can be conveniently used in detergent compositions.

Abstract: Alkaline cellulases named K-64, K-19, and K-520; microorganisms of the genus Bacillus producing these alkaline cellulases; and each process for producing them are disclosed. The alkaline cellulases have an optimum pH range at an alkaline region and are stable at a wide pH range. The enzymes of the present invention are not adversely affected by the addition of detergent components such as surfactants, proteases, chelating agents, and the like, and, accordingly, can effectively be used as a detergent component.
