Recently more and more attention is given to a microbiological method of ecosystems cleaning. Its advantages are efficiency, profitability, ecological purity and safety, technological flexibility and possibility of repeated processing of “chronic” pollution, and also wide range of admissible levels of pollution. Results of field experiment on neutralization of 5000 m3 of the oil slime stored in the territory of an oil and gas field Karazhanbas (Republic of Kazakhstan) by means of consortium of microorganisms Ochrobactrum sp. ИБ ДТ- 5.3/2 и Acinetobacter sp. ИБ ДТ-5.1/1. are given. In 90 days the content of oil products in withdrawal decreased by 4,99-8,64% while in control test this indicator made only 0,39%. In the samples processed by consortium, number heterotrophic bacteria increased by 2-4 orders and the microorganisms oxidizing hydrocarbons - by 1-2 orders. In control test during experiment concentration of biomass the heterotrophic bacteria and the microorganisms oxidizing hydrocarbons practically didn’t change. The applied consortium of microorganisms can form further a basis of biological product for cleaning of environment of oil pollution.
