摘要
The effect of oil contamination on bacteria in a soddy-podzolic soil was studied. Oil was introduced into the soil 8, 11, and 17 years ago. It was found that oil contamination has exerted long-term negative effects on the number and biomass of the soil bacteria. The deficiency of available phosphorus was one of the major negative factors affecting these parameters in the old-contaminated soils. The application of Na2HPO4 to the contaminated soils eliminated this negative effect. The effect of oil contamination on the taxonomic diversity and structure of the bacterial community in the studied soil was determined with the help of denaturating gradient gel electrophoresis.
