[Intergeneric Escherichia coli-Streptomyces conjugation as a means for the transfer of conjugative plasmids into producers of antibiotics chlortetracycline and bialaphos].
A system for introduction of plasmids into industrial producers of antibiotics chlortetracycline and bialaphos using intergeneric conjugation of Escherichia coli and Streptomyces was developed. Low level stability of inheritance of autonomously replicating DNA in recipient strains was shown. Site-specific integration of the conjugative-integrative vector pTO1 provided stable plasmid maintenance within the chromosomes of Streptomyces aureofaciens and S. hygroscopicus. Phenomenon of disturbance in differentiation and antibiotic production, resulting from pTO1 integration into S. hygroscopicus chromosome, was discovered.
