<p>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.</p> |
