[The stability of plasmid pSG 1912 inheritance by the cells of Streptomyces globisporus 1912 and of heterologous streptomycete strains].

Abstract

Streptomyces globisporus 1912 strain contains plasmid pSG1912 (11, 2kb) determining some phenotypic properties. The plasmid is able to exist and to provide for exhibition of these properties both in autonomous and integrated state. It is established that plasmid pSG1912 and constructed derivatives are stably inherited by cells of S. globisporus 1912 and heterologous hosts, and besides, molecular size and determined properties being retained.
