[Formation of the anthracycline antibiotics, beromycin and nogalamycin, by a new actinomycete species, Streptomyces glomeratus sp. nov].

Culture 3980 was isolated from a soil sample and described as a new species, Streptomyces glomeratus sp. nov. It was found that the culture produced simultaneously 2 close anthracycline antibiotics, i. e. nogalamycin and beromycin, which were synthesized mainly in the mycelium. S. glomeratus differed from the nogalamycin and beromycin-producing organisms described earlier.
