Japan, was found to produce a potent antibiotic. This compound, BE-24566B (1), was isolated from the mycelial cake of cultural broth, and was shown to have the unique structure in Fig. 1. BE-24566B possesses potent antibacterial activity against Gram-positive bacteria including methicillin-resistant Staphylococcus aureus (MRSA). This paper describes the strain, production, isolation, physico-chemical properties and structure elucidation of this new antibiotic. Characterization of the strain followed the method adopted by the International Streptomyces Project (ISP)1}. The strain A24566 formed well developed and branching substrate mycelia and aerial mycelia, but fragmentation of the substrate mycelia was not observed. The whole cell hydrolysate contained L,L-diaminopimelic acid. The spore chains of the strain were spirals and the spore surface was rugose. The spore mass was gray, becoming black and moist with maturity. Melanoid pigments and soluble pigments were absent. Utilization of carbon sources was examined according to the method of Pridham and Gottlieb2) on the agar medium culture at 28°C for 14 days. D-glucose, D-xylose, L-arabinose, L-rhamnose, D-fructose, raffinose, sucrose and D-galactose were utilized for growth. Utilization of inositol was doutful and salicin was not utilized by the strain.
