title: Platomycins A and B I Taxonomy of the producing strain and production, isolation and biological properties of platomycins.
abstract: Two new antibiotics, platomycins A and B, belonging to the phleomycin-bleomycin family, were isolated from the culture filtrate of Streptosporangium sp. MK-78. This strain has been identified as a new variety of Streptosporangium violaceochromogenes. Both platomycins A and B are active against a variety of Gram-positive and Gram-negative bacteria, and also inhibit solid Sarcoma 180 and Ehrlich ascites carcinoma.
