“…A significant aspect of the study of microorganisms in polar habitats is their ability to secrete various lytic compounds at low temperatures, which can be used in biotechnological processes and in reclamation processes carried out in similar temperature conditions [52][53][54][55][56]. The results of testing isolated bacteria and yeasts as oil destructors are provided in the work presented in [34]. The ability to grow at different temperature conditions was previously demonstrated in Table 3.…”

“…Microbial cultures isolated from Arctic aerosols were tested for their ability to degrade oil by sowing on agarized and liquid 8E mediums [34]. Up to 1-5% of high-viscosity oil from the Usinsk field (Komi Republic, Russian Federation) was added to the medium as the only carbon source.…”

“…Psychrotolerant microorganisms capable of active destruction of oil at low temperatures include bacterial strains Sp-1, Sp-16, Sp-18, Sp-22, Sp-22-1, and Sp-116, as well as yeast Sp-71, Sp-91 (Figure 3B,C). The most active oil destructor turned out to be the psychrotolerant strain Rhodococcus sp Sp-116 [34], deposited in the collection of bacteria, bacteriophages, and fungi under No. B-1388.…”

Atmospheric sounding using the Tu-134 Optik aircraft-laboratory was conducted in September 2020 over the seas of the Russian sector of the Arctic Ocean, namely the Barents, Kara, Laptev, East Siberian, Chukchi and Bering seas. Unique samples of atmospheric aerosols at altitudes from 200 and up to 10,000 m were taken, including samples for the identification of cultivated microorganisms and their genetic analysis. Data on the concentration and diversity of bacteria and fungi isolated from 24 samples of atmospheric aerosols are presented; the main phenotypic and genomic characteristics were obtained for 152 bacterial cultures; and taxonomic belonging was determined. The concentration of cultured microorganisms detected in aerosols of different locations was similar, averaging 5.5 × 103 CFU/m3. No dependence of the number of isolated microorganisms on the height and location of aerosol sampling was observed. The presence of pathogenic and condto shitionally pathogenic bacteria, including those referred to in the genera Staphylococcus, Kocuria, Rothia, Comamonas, Brevundimonas, Acinetobacter, and others, as well as fungi represented by the widely spread genera Aureobasidium, Aspergillus, Alternaria, Penicillium, capable of causing infectious and allergic diseases were present in most analyzed samples. Obtained data reveal the necessity of systematic studies of atmospheric microbiota composition to combat emerging population diseases.
