title: M-9337, a new antistreptolysin, produced by Streptomyces sp.
abstract: A new biologically active substance, M-9337, was obtained from Streptomyces strain M-9337, a soil isolate. The producing organism was subsequently determined to be a new strain and named Streptomyces antihaemolyticus M-9337. The active substance was prepared as white yellow powder from culture broth by solvent extraction and silica gel thin-layer chromatography. It showed no antimicrobial activity and potent inhibitory activity against streptolysin, a type of hemolysin.
