Antibiotic cochliodinol and production by chaetomium, cochliodes and chaetomium globsum

摘要

A purple pigment, named cochliodinol, C32H32N2O4, has been isolated from three isolates of Chaetomium cochliodes and from two isolates of Chaetomium globosum. The pigment is produced intracellulary on a wide range of media in quantities up to 0.45 mg/ml. The rate of production for a given isolate is proportional to its growth. Cochliodinol exhibits antibacterial fungistatic and fungicidal properties.
