摘要

Polyene antifungal antibiotics are produced by fermenting a culture medium containing assimilable carbon and nitrogen sources with the new microorganism named Streptomyces sp. strain SF-1 (ASA) NCIB 11738. A new tetraene antifungal antibiotic is prepared by the above process, and also the known antifungal antibiotic Pimaricin.
