BIOREMIDIATION OF LANDS POLLUTED WITH PETROLEUM PRODUCTS WITH THE HELP OF CARBONATED SAPROPEL AND BIODRUG "NAFTOKS"
The work is devoted to theoretical and experimental substantiation of bioremediation of soils contaminated with petroleum products resulting from their transportation and processing of oil relates to the field of environmental protection, soil recovery for agriculture. The aim of the research is to investigate the possibility of biological treatment of oil-contaminated soils through the combined use of calcareous sapropel and biological product a series of «NAFTOKS» on the basis of live aerobic hydrocarbon-oxidizing bacteria of the genus Pseudomonas. In the experiment investigated the possibility of biological treatment of soils from oil products using carbonate sapropel and aerobic hydrocarbon-oxidizing microorganisms, evaluate the effectiveness of their combined use, analysis of residual phytotoxicity of sod-podzolic soil after the rehabilitation measures. It has been established that bioremediation of soil contaminated with diesel fuel, the possible use of combined ameliorant, consisting of carbonate sapropel treated with the biopreparation "Naftoks" on the basis of aerobic hydrocarbon-oxidizing bacteria of the genus Pseudomonas.The decrease in the content of oil products in the soil during 90 days of experiment was 86 - 88 %. The practical significance of the work lies in the possibility of rehabilitation and return to agricultural use of contaminated with petroleum hydrocarbons of the soils of agricultural lands of the Central-Chernozem region of Russia in the conditions "in situ" through the combined application of agrotechnical measures, the carbonate sapropel and of a biological product on the basis of strains of aerobic oil-oxidizing microorganisms of the genus Pseudomonas.
