The fermentation of a substrate selected among erythronolide B, erythronolide A and erythronolide A oxime with a novel mutant, Streptomyces antibioticus ATCC 31771, obtained from an industrial stock for the production of oleandomycin, said novel mutant being incapable of producing the same oleandomycin, permits novel macrolide antibiotics to be produced, having not only an activity range like that of erythromycin, but characterized by a greater stability in acidic environment, whereby for the administration of the antibiotic it is no longer necessary to have recourse to esters and/or salts highly toxic for the organism. |

New anthracycline glycosides designated MA 144-G1, -G2, -L,-S1, -N1, -U1 and -Y which inhibit the growth of gram-positive bacteria and mammalian tumors are produced by fermentation of certain species of Streptomyces and by the chemical or enzymatic conversion of certain anthracycline glycosides. New microbiological and chemical processes are also provided for preparation of the anthracycline glycosides MA 144-S2 and -U2 which have been found to be identical with the previously reported anthracyclines, marcellomycin and musettamycin. |
