title: Pamamycin: a new antibiotic and stimulator of aerial mycelia formation.
abstract: Pamamycin is a new antibiotic isolated from Streptomyces alboniger ATCC 12461. The antibiotic is active in vitro against Gram-positive bacteria, Neurospora, and Mycobacteria. The compound also acts as a streptomycete differentiation effector. It stimulates aerial mycelia formation in the producing organism. The new antibiotic of elemental composition C36H63NO7 is completely different from puromycin, also produced by this strain. The present communication deals with the isolation, properties, and preliminary characterization of pamamycin.
