The taxonomic composition of microbial communities of Lake Baikal surface microlayer was studied by pyrosequencing of the 16S rDNA amplicons. Statistically reliable differences were found between bacterioneuston of the shallow and deep-water stations. The shallow station community was characterized by higher diversity than the deep-water one.

Com- pared to the water column, diversity of cultured heterotrophs was low, indicating formation of stable micro- bial communities at the air-water interphase interface.

Activity of microbial communities was determined. While both spring biotopes were dominated by members of three bacterial phyla, Proteobacteria, Bacteroidetes, and Firmicutes, they differed drastically in the composition of predominant phylotypes (at the genus level).

Data on metagenomic analysis of the microbial community of the intestine of the Comephorus dybowski are presented for the first time. It was established that the bacterial community is characterized by a significant species diversity. In its composition 301 phylotypes (OTU) belonging to 23 phyla (out of which six are candidate, including the Thermobaculum, Gracilibacteria, Candidatus Saccharibacteria, TM6, Latescibacteria, and Parcubacteria) were detected.

- Phylogenetic analysis of bacteria from the Dead Sea and West Antarctic utilized 16S rRNA gene sequences, identifying key species like Bacillus licheniformis and psychrotolerant bacteria from Galindez Island.
- Two strains, a thermotolerant Staphylococcus sp. and various species of Frondihabitans, were discovered in unique habitats, emphasizing their ecological isolation and diversity in extreme environments.
- The study highlighted that Frondihabitans strains were the most common among the aerobic chemoorganotrophic bacteria in Antarctic ecosystems, showcasing their adaptability.
