Simple screening method for identification of nonpleiotropic mutants for exoenzyme production

Abstract

A differential medium that distinguishes between pleiotropic and nonpleiotropic mutants for exoenzyme production has been developed for Staphylococcus simulans biovar staphylolyticus. The medium will facilitate genetic analysis of exoenzyme production by this organism. Generally useful strategies for increasing the sensitivity of indicator plates for detection of exoenzyme activities are presented. Our study of the regulation of exoenzyme production by Staphylococcus simulans biovar staphylolyticus (S. staphylo
