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 belongs to a new species of Streptomyces for which the name S. cervinus is proposed. The antibiotics possess a strong inhibitory activity against anaerobic bacteria, such as Clostridium perfringens, Peptococcus prevotii and Bacteroides fragilis.
