Antibiotic fki-1778 and process for producing the same

摘要

A microorganism belonging to filamentous fungi, capable of producing antibiotic FKI-1778A and/or FKI-1778B and/or FKI-1778C and/or FKI-1778D is cultured in a culture medium to thereby accumulate the antibiotic FKI-1778A and/or FKI-1778B and/or FKI-1778C and/or FKI-1778D in the culture mixture. The antibiotic FKI-1778A and/or FKI-1778B and/or FKI-1778C and/or FKI-1778D is collected from the culture mixture. The thus obtained substance is promising as drugs, veterinary medicines or agrichemicals having a growth inhibiting activity to microorganisms, nematodes and arthropods or as drugs exhibiting a growth inhibiting activity to carcinoma cells.
