Abstract

Aminocyclitol analogs of gentamicin C.sub.1, C.sub.2 and C.sub.1a and the corresponding compounds acylated on the 1-, 3- and 2'-amino groups with an .omega.-amino-.alpha.-hydroxy-lower-alkanoyl group are prepared by culturing a nutrient medium containing carbohydrates, a source of assimilable nitrogen, essential salts and an added aminocyclitol with a mutant of Micromonospora purpurea and acylating the product with an ester of an .omega.-(N-benzyloxycarbonyl)amino-.alpha.-hydroxy-lower-alkanoic acid followed by catalytic hydrogenolysis of the benzyloxycarbonyl group.
