Abstract
A proteinase-resistant cellulase, a microorganism producing the same, and a process for producing such a proteinase-resistant cellulase is disclosed. The cellulase can be used as an additive to detergent compositions for washing clothes containing a proteinase, without immobilization or stabilization by chemical modification. The proteinase-resistant cellulase can be produced by a novel microorganism, Aspergillus niger KSM-24 [deposited with Fermentation Research Institute, Agency of Industrial Science and Technology (FERM BP-3359)].
