Potential of Eisenia andrei in complex cleaning of soils contaminated with fuel oil

The technology of soil remediation contaminated with fuel oil at a concentration of 150 g/kg of soil for one year in Western Siberia using microbiological preparations and earthworms was developed. Earthworms have great potential for removing hydrocarbons from the soil, even at high concentrations up to 100 g / kg. The introduction of microbiological preparations increased the survival and reproductive potential of worms in oil-contaminated soils and contributed to a significant reduction in the concentration of hydrocarbons of fuel oil for 20-22 weeks in the laboratory and field experiment. These results suggest that earthworms are effective in bioremediation of even very contaminated soils with a concentration of fuel oil up to 100 g/kg when combined with microbiological preparations containing cultures of bacteria Paenibacillus pabuli, Azotobacter vinelandii, Lactobacillus casei, Clostridium limosum, Cronobacter sakazakii, Rhodorulla mucilaginosa, Cryptococcus albidus, yeast Saccharomyces, Candida lipolitica, Candida norvegensis, Candida guilliermondii, fungi Aspergillus and Penicillium as well as actinomycetales...
