A system for introduction of plasmids into industrial producers of ant
ibiotics chlortetracycline and bialaphos using intergeneric conjugatio
n of Escherichia coli and Streptomyces was developed. Low level stabil
ity of inheritance of autonomously replicating DNA in recipient strain
s was shown. Site-specific integration of the conjugative-integrative
vector pT01 provided stable plasmid maintenance within the chromosomes
of Streptomyces aureofaciens and S. hygroscopicus. Phenomenon of dist
urbance in differentiation and antibiotic production, resulting from p
T01 integration into S. hygroscopicus chromosome, was discovered.
