Аннотация: The paper deals with the phylogenetic and functional microbial diversity in the samples of umbricluvisol contaminated and uncontaminated with hydrocarbons and of urban stratozem. High-throughputsequencing of the V3–V4 region of the 16S rRNA gene revealed predomination of bacteria of the phyla Proteobacteria,Actinobacteria, and Acidobacteria in the studied soil samples. Bacteria of the genera Sphingomonas,Bradyrhizobium, and Pseudolabrys in the samples of umbric luvisol and bacteria of the genera Brevundimonas,Stenotrophomonas, and Streptomyces in urbostratozem had the greatest potential functional activityin conversion of nitrogen compounds, degradation of chloroalkanes, chloroalkenes, and benzoate. Strains ofStenotrophomonas maltophilia, which degraded oil, petroleum products, and polycyclic aromatic hydrocarbons(PAHs, phenanthrene, anthracene, and pyrene) were isolated from oil-contaminated soils. Undermicrocosm conditions, microorganisms of umbric luvisol efficiently degraded various components of naphthenic-methane and methane-naphthenic oil. While the content of aromatic components in naphthenicmethaneoil degraded by the soil microbial community and by the community enriched with S. maltophiliastrain P420c was almost the same, in the variant with bioaugmentation the degradation process of these componentsproceeded 14 days faster. The enrichment of soil with specific degraders of PAHs and aromatic compoundsmay be appropriate for the soils of northern regions with a low duration of the summer period, whichare polluted with oil with a high content of aromatic and asphalt-resinous compounds.
