Microbiocenoses of Oil-Polluted Soils

摘要

The state of soil microbiocenoses at different levels of oil pollution was assessed. The microbiological activity of two types of soils (sod-podzolic and typical black earth) under the conditions of stress caused by oil pollution was determined. The regularities in variation of the ratio and total number of the main groups of microorganisms in different soil types were reveled. The compositions of microorganism species in polluted soils were determined. The dynamics of changes in microbiocenoses after one-time oil spiking was traced. A number of microbiological parameters, which can serve as markers of oil pollution in soil, were proposed.
