BIOTECHNOLOGICAL POTENCIAL OF BACTERIA OF RHODOCOCCUS STRAIN AND THEIR METABOLITES

National University of Food Technologies, Kyiv

The literature and own experimental data, concerning biotechnological potential of bacteria of Rhodococcus strain as destructors of aromatic, heterocyclic and aliphatic xenobiotic compounds (naphtalet, xylol, toluene, ethylbenzene, indole, nitrophenolum, trichloroethylene, hydrocarbons of oil, etc.), and also as producers of valuable metabolites (surfactants, antibiotics, exopolysaccharides, enzymes) are given. Surface-active substances (surfactants) are essential products of microbial synthesis, as these have significant advantages over synthetic analogs as biodegradability, stability over a wide range of temperature, pH, and can be produced from the wastes of other industries. The use of Rhodococcus metabolites in environmental protection technologies, medicine, agriculture, and also participation of Rhodococcus strain in biotransformation processes for production of flouver (carvon, geraniol), biodiesel, butiramide, acrylic acid, etc. is discussed.

The own experimental data concerning the intensification of Rhodococcus erythropolis IМV Ас-5017 surfactant synthesis and practical application are summarized. It was determined that the oil destruction degree in water and soil reached 80–93% on the 30th day in the presence of cells of strain IМV Ас-5017, as well as exocellular metabolites with surface-active and emulsifying properties. It was shown that surfactant of R. erythropolis ІMV Ac-5017 inherent the antimicrobial activity against the number of microorganisms, including phytopathogenic bacteria. The reduction of quantity of living cells by 74–97% was observed after treatment (1–2 h) of suspension of test-cultures with surfactant preparations.

Key words: bacteria of Rhodococcus strain, destruction of xenobiotics, biotransformation, surfactants, polysaccharides, enzymes.
