Abstract
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.
