Changes in the Number and Species Variety of Bacteria in Oil-Polluted Soils

Abstract

Herein we have assessed the state of soil bacterial communities at different levels of pollution with oil. The dependences of the change in the total abundance of non-spore-forming bacteria and bacilli in sodpodzolic soil and typical chernozem have been obtained. The species composition of microorganisms in polluted soils has been assessed. The dynamics of the changes in the structure of bacterial communities with time after single oil pollution has been traced. Several microbiological parameters which can be used as diagnostic tools in case of oil pollution of soil have been found.
