Cervinomycin A1 and A2, new antibiotics active against anaerobes, produced by Streptomyces cervinus sp. nov.

Abstract

Two new antibiotics, cervinomycin A1 and A2, were isolated from the culture filtrate of strain AM-5344, a soil isolate. The strain was found to belong to a new species of the genus Streptomyces for which the name Streptomyces cervinus is proposed. The antibiotics possess a strong inhibitory activity against anaerobic bacteria, such as Clostridium perfringens, Peptococcus prevotii and Bacteroides fragilis.
