A new antibiotic,, asukamycin, produced by Streptomyces
Abstract
Asukamycin, a new antibiotic, has been isolated from the culture broth of a streptomycete designated as Streptomyces nodosus subsp. asukaensis. The antibiotic inhibits the growth of Gram-positive bacteria including Nocardia asteroides. The empirical formula of antibiotic asukamycin has been proposed as C29H22N2O9 (M.W. 542). An acute toxicity of the antibiotic in mice is LD50 48.5 mg/kg by intraperitoneal injection and it has no effect on mice when it was administered by 450 mg/kg per os.
