NOVEL K99-5278 SUBSTANCES AND PROCESS FOR PRODUCING THE SAME

摘要

Microorganisms belonging to the genus Streptomyces and being capable of producing K99-5278A, K99-5278B and K99-5278C, which are drugs efficacious against infection with so-called fungi such as molds and yeasts, are culture d in a medium to accumulate the K99-5278A, K99-5278B and K99-5278C in the culture medium. Then the K99-5278A, K99-5278B and K99-5278C are collected fr om the culture medium. The thus obtained substances are expected as being usefu l as novel antifungal agents.
