A new antibiotic, designated as neocopiamycin A, is useful as antifungal agent. Neocopiamycin A is fermentatively produced as a minor component, in addition to copiamycin, by a microorganism Streptomyces hygroscopicus var. crystallogenes (FERM BP-576) which is known to produce the known antibiotic copiamycin. |
