title: [Microcin R51 and a plasmid determining its synthesis].
abstract: A new microcin produced by an Citrobacter R51 strain has been detected. This antibiotic has been shown to inhibit the growth of a number of Gram-negative as well as Gram-positive strains of bacteria on the minimal medium plates. The properties of partially purified microcin were characterized. Constitutive synthesis of microcin is determined by a conjugative plasmid. The genes of microcin synthesis and immunity were cloned on a plasmid and plasmid vehicles. A physical map of the 12 kb fragment coding for the production of microcin R51 and immunity to this antibiotic is presented.
