A mutant of an extracellular enzyme-producing microorganism belonging to genus Bacillus, which is resistant to a cell membrane synthesis inhibitor, including vancomycin and ristocetin, is disclosed. The cell membrane synthesis inhibitor-resistant mutant can produce such an enzyme as cellulase, protease, or amylase about 2 to 4 times of the parent strain. Such a mutant can be produced by subjecting an extracellular enzyme-producing microorganism tot a mutation treatment, and culturing said microorganism in a culture medium containing a cell membrane synthesis inhibitor.
