Abstract

A new antimicrobial agent, proceomycin, has been isolated from fermentation broths of a strain of Streptomyces named Streptomyces albolongus nov. sp. The antibiotic is a weakly acidic substance of yellowish-orange color and inhibits the growth of a variety of Gram-positive bacteria.

This paper summarizes the characteristics of the new Streptomyces strain and some of the chemical, physical and biological properties of proceomycin.
