Regulatory enzymes for the screening of streptomycin producing mutant strains of Streptomyces griseus.

Abstract

Intermediary enzymes of streptomycin biosynthesis-arginine amidinotransferase and alkaline phosphatase were located at the early fermentation stages. Their relationship with streptomycin production by Streptomyces griseus strains GX-19 and MR-20 was determined and the use of this relationship was made for the screening of streptomycin producing mutant strains.
