Abstract

It found that the spread of microorganisms in the soil horizons depends on different types of oil-contaminated loamy grey soils and correlated with a molecular mass of oil products. For carrying out bioremediation was necessary allocation of new microbial cultures with high metabolic activity. In this regard, from a variety of oil-contaminated areas were isolated 255 microbial cultures. Because of the ability of isolates to active growth showed 3 strain - DP304 B7, B1Ag8G, N 313-C14. The use of a biological product "Peroyl" created on the basis of strain Micrococcus luteus and Rhodococcus erythropolis B1Ag8G DP 304 B-7 enables up to 30 days to degrade petroleum hydrocarbons 44.4-97.2%, while the titer of soil microorganisms increased to 28.2-93.5%. Augmentation of active strains of microorganisms in oil contaminated soils promotes biodegradation bicycloaromatic, monocycloaromatic compounds, toluene resins and asphaltenes. The association of bioremediation operations beginning in early autumn contributes, on the one hand, the adaptation of microorganisms to low temperature followed by earlier timing of microbiological processes, on the other hand, reduces the water consumption
