For the first time three isolates of hydrocarbon-oxidizing microorganisms of Pseudomonas lundensis, Aeromonas eucrenophyla, Pseudomonas fragi were isolated from the oil-contaminated waters of the Kola North. The aim of this work was to study the hydrocarbon-oxidizing activity of the indigenous strains and the possibility of using those as a basis for a biopreparation for water purification after hydrocarbon pollution. The paper evaluates the efficiency of oil and diesel fuel degradation by fluorometric method, as well as the bio-emulsifying and hydrophobic activities of monocultures and the association of hydrocarbon-oxidizing microorganisms. The dynamics of bacterial growth was studied at different temperatures of cultivation based on the increase in optical density in a mineral medium with diesel fuel. Moreover, the absence of antagonistic activity was noted when composing the monocultures of oil-degrading bacteria into associations. The ability of the studied strains of microorganisms to grow on various hydrocarbon substrates was also shown. Based on the obtained results, it can be concluded that the bacterial strains are promising for biodegradation of hydrocarbons and can be used in bioremediation of environmental pollution.

Keywords:hydrocarbon-oxidizing bacteria, water, oil pollution, microbial consortium, Pseudomonas spp., Aeromonas spp
