In this article we have carried out a comparative study of hydro-carbon-oxidizing activity of S-and R-morphological types of oil oxidizing Actinobacteria from the collection of Kuban State University. Signifi-cant differences observed in parameters of growth between S- and R-forms of oil oxidizing Actinobacte-ria. In S-forms it is higher than the maximum specific growth rate, which is typical for a wide range of hy-drocarbon degradation and a high degree of degrada-tion of pollutants. In experiments with the use of oil as a substrate and heavy oil S-forms, Actinobacteria quickly adapted to the environmental conditions

In the article we have studied the technology of obtaining a biomass of oil oxidizing microorganisms in a nutrient medium containing vegetable oil as the sole source of carbon and energy. In vitro and in soil experiment we have confirmed the effectiveness of the resulting biomass at work on bioremediation of oil contaminated sites. It is shown that the use of vegetable oil during culturing allows obtaining the same amount of biomass and carbohydrate raw materials, but the efficiency of its use is 20% higher, in average

We studied the resistance of the eight strains of oil-destructive actinomycetes, isolated from the oil-contaminated ecosystems to heavy metal salts when cultivatiwng with different carbon sources. Furthermore we researched feasibility to use those microorganisms for bioremediation of oil- contaminated sites with high level of heavy metals

This article is devoted to the biotechnological properties of the oil-degrading strain Rhodococcus erythropolis B2, which allow us to use microorganism B2 as a base of biopreparation: hydrocarbon- destructive potential, growth characteristics on the different media, producing phytohormones and biosurfactants, adhesive and floatation activity, and also laboratory and field tests
