ABSTRACT:
A streptomycin dependent mutant of a microorganism of the genus Escherichia which contains a plasmid containing genetic information controlling streptomycin independence maintains its properties when cultured in a medium devoid of streptomycin. The plasmid may also contain genetic information controlling the production of a chemical compound by the microorganism. Fermentation cultures of such microorganisms in media devoid of streptomycin do not lose their industrially desirable ability to synthesize useful compounds.
