A new polyene class antibiotic, aurantinin (KM-214), was isolated from the fermentation broth of Bacillus aurantinus MASUMA and OMURA sp. nov. The substance is a conjugated triene with a molecular weight of 618 and molecular formula C35H54O9, and melts at 139 approximately 140 degrees C. The antibiotic is active in vitro against Gram-positive bacteria, but not against yeast and fungi.
