ABSTRACT:
Novel alkaline cellulase K, CMCase I and CMCase II are obtained by isolation from a culture product of Bacillus sp KSM-635.
These enzymes stably work in a wide range including an alkaline side, and their activity is shown even at low temperatures. Further, they have a strong resistance to surface active agents, chelating agents and proteinases. Therefore, they can be effectively utilized not only as an additive for clothing detergents, but also as a biomass and in other fields.
