Biogeochemical Engineering: Technologies for Managing Environmental Risks

Abstract

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.
