The recultivation of soils contaminated with oil using the vermiculture of earthworms and their probiotics

Abstract

Abstract The recultivation technology for soils contaminated with oil in the concentration of 50 g/kg in Western Siberia with the use of microbiological preparation received from coprolites of earthworms Eisenia fetida and vermiculture of earthworms E. fetida, E. andrei, D. veneta was developed. The coprolites microflora composition of the earthworms E. fetida was studied. The microbiological preparation from coprolites of the earthworms was received. Microorganisms – oil destructors were isolated, which were used as the basis of the microbiological preparation “Muck” containing Pseudomonas aeroginosa, Bacillus careus, Bacillus mucoides, Bacillus thuringiens, Pseudomonas putida, CFU – 3.3*108. The following characteristics were determined: the remediation effectiveness for the soil contaminated with oil in the concentration of 50 g/kg when using the microbiological preparation “Muck” and earthworms E. fetida, E. Andrei and D. veneta.
