Abstract

During the screening course of antibiotics from Streptomyces in this laboratory, a new crystalline antibiotic was isolated from a cultured broth that had been inoculated with strain A-59 of Streptomyces sp.

A new antibiotic, A-59 substance, is of sulfur-containing peptide nature, and highly active against Gram-positive bacteria.
