Abstract
The bacterial hemoglobin vhbgene was cloned from sliding bacterium Vitreoscillasp. as an element of the system ensuring survival of this microorganism in an environment that contains insufficient amount of oxygen. The vhbgene was transferred fromEscherichia colito some Streptomycesstrains, producers of antibiotics, by the method of intergeneric conjugation using conjugative–integrative plasmid vectors pIH1 and pCH2. The stability of plasmid DNA inheritance was analyzed in the genomes of exconjugants. A positive effect of the vhbgene on processes of conjugation and antibiotic production in a number of examined strains was shown.
