Abstract
In work influence perftordecalin on growth and development of microorganisms different groups is investigated. Entering into liquid nutrient mediums perftororganical connections with gastransport function is shown, that, in particular perftordecalin in concentration of 0.2 2% provides a gain of a biomass of microorganisms. The opportunity of use perftordecalin in biotechnological processes cultivation bacteria of Rhodococcus, Escherichia, Pseudomonas and Bacillus and micomicetes Penicillium, Fusarium and Saccharomyces is shown.
