Proteinase-resistant cellulase, microorganism that produces it and its production process.

ARISE cellulase RESISTANT proteinase, a microorganism that produces it and a process for producing said cellulase RESISTANT proteinase. The cellulase may be used as an additive DETERGENT COMPOSITIONS CONTAINING WASHING CLOTHES proteinase, without immobilization OR STABILIZATION BY CHEMICAL MODIFICATION. Cellulase RESISTANT proteinase may be produced using a new microorganism, "Aspergillus niger" KSM-24 [DEPOSITED IN THE RESEARCH INSTITUTE fermentations AGENCY OF INDUSTRIAL SCIENCE AND TECHNOLOGY (FERM BP-3359)].
