“…A quantitative assessment can be made either by analyzing the microbiological (enzymatic activity of soils and other media) properties or by assessing the degradation mechanism of pollutants. The development of biogeochemical technology helps develop biosorbents that are used to eliminate the consequences of hydrocarbon pollution in oil and gas facilities [22].…”

This research aims at one of the most important economic and environmental problems - the elimination of the consequences in case of emergency spills while cleaning petroleum products. The objectives of the study include the development and production of new biological products and biosorbents based on carbon-oxidizing microorganisms, testing the developed technologies for environmental risk management to eliminate the consequences of emergency petroleum product spills, creating an algorithm for conducting preliminary studies in vitro for their subsequent use in situ. A biological product and a biosorbent were developed to clean soils and water from hydrocarbon pollution were developed based on the developed consortiums of strains of carbon-oxidizing microorganisms. Biogeochemical technologies for producing and applying new biological products and biosorbents have been developed. The natural biogeochemical structure of the ecosystems is restored, and this is revealed by studying the species composition of the microbiocenosis or by analyzing the enzymatic activity of the microorganisms in soil or water. Finally, the effectiveness of the risk management method based on biogeochemical and, in particular, microbial engineering methods under conditions of oil pollution has been proven.

Важной задачей современности является разработка экологичных методов очистки почв от загрязнения нефтью и нефтепродуктами. Ранее нами была доказана эффективность метода сорбционной биоремедиации для очистки от нефти ряда почв Восточно-Европейской равнины. Целью данной работы было разработать аналогичный метод для рекультивации подзолистых почв, распространенных на территории Северо-Западной Сибири, где добывается основная часть российской нефти. На основании результатов микрополевого и вегетационного экспериментов с подзолом иллювиальножелезистым, загрязненным 6 и 12% нефти, сделан вывод о высокой эффективности метода сорбционной биоремедиации этих почв. В случае умеренно загрязненной почвы наилучшим сорбентом оказался смешанный сорбент АУД на основе гранулированного активированного угля и диатомита, а для сильно загрязненной почвы – композитный сорбент на основе АУД и торфа. Проведение сорбционной биоремедиации этих почв с использованием биопрепарата Микробак на фоне внесения оптимальных доз разработанных сорбентов уже к концу 1-го или 2-го сезонов может обеспечить снижение концентрации нефтепродуктов до уровня, допустимого для рекультивированных почв Ханты-Мансийского автономного округа, предназначенных для лесного использования, а через 2-3 сезона – и для почв сельскохозяйственного назначения. Механизм положительного действия этих сорбентов объясняется снижением токсичности загрязненных почв за счет преимущественно обратимой сорбции углеводородов нефти и их метаболитов, поддержания оптимальной влажности и рН почвы, а также повышения устойчивости микроорганизмов и растений к неблагоприятным факторам, что создает условия для ускоренного разложения поллютантов и минимизации показателей интегральной токсичности почв. An important problem of modern time is the development of environmentally friendly methods for remediating soils contaminated with crude oil and petroleum products. Previously, we proved the effectiveness of an adsorptive bioremediation approach for remediation of petroleum-contaminated soils of the East-European Plain. The purpose of this work was to develop a similar method for the remediating podzolic soils common in North-Western Siberia, where the bulk of Russian oil is produced. It was concluded from the results of microfield and pot experiments with illuvial-ferruginous podzol, contaminated with 6 and 12% crude oil, that the method of the adsorptive bioremediation is highly effective for those soils. At the same time, in case of moderately contaminated soil, the best sorbent for that purpose is a mixed sorbent ACD based on granular activated carbon and diatomite, while a composite sorbent ACDP (a mixture of ACD and peat) demonstrated the best results for adsorptive bioremediation of the highly contaminated soils. Bioremediation of those soils on the background of optimal doses of the sorbents could reduce the concentration of petroleum products to the permissible level for recultivated soils of the KhantyMansiysk Autonomous Okrug intended for forest use by the end of the first or second warm seasons, and to the level for agricultural use – after two or three years of the treatment. Besides, the indicators of the soil integral toxicity will be reduced to a minimum to the end of the treatment. The mechanisms of the sorbents positive influence are explained by the reduction of soil toxicity due to the predominantly reversible sorption of petroleum hydrocarbons and their metabolites; due to maintaining optimal soil moisture and pH, as well as due to increasing resistance of microorganisms and plants to adverse factors. All these factors create optimal conditions for accelerated biodegradation of pollutants and minimizing the integral soil toxicity.
