【 摘 要 】

The paper presents the results of an experiment on the biological purification of permafrost soils from oil pollution with use biological preparations on the basis of hydrocarbon-oxidizing microorganisms. Biological preparations were used in two modifications - in liquid form as a suspension and in dry form as a suspension immobilized on organic granules. It has been established that dry form of a biological preparation is more effective for the purification of permafrost soils from oil than a liquid microbial suspension. For 1 month in dry conditions and a strongly alkaline soil environment, the use of a dry biological preparation allowed reducing the concentration of oil pollution by up to 60 %. The change of the chemical structure of extracts of soil samples was investigated with use the method of IR-Fourier spectroscopy. The increase of the relative absorption coefficients of oxygen-containing groups and bonds pointed (indicated) on the course of oxidative destruction.
