In order to optimize the bioremediation methods for soils contaminated with oil and oil products, the analysis of the indigenous plant species on the resistance to the oil contamination is conducted. The indicator of the delayed chlorophyll fluorescence and the total number of organotrophic bacteria in the plant rhizosphere in the introduction into the soil of crude oil and its processing products are measured as the test-parameters. From rhizosphere soil the hydrocarbon-oxidizing bacteria of the Bacillus, Rhodococcus, Pseudomonas genera are isolated and identified.
