Mass death of endemic sponges accompanied by the growth of cyanobacterial biofilms on their bodies has been registered in recent years in Lake Baikal. These biofilms are formed by the cyanobacterium Tychonema sp., which grows on various types of substrates in the littoral zone and is often found on sponges. The aim of the study was to conduct an experiment on co-cultivation of Tychonema sp. with Baikalospongia sp. primomorphs to test the hypothesis about the tropism of Baikal cyanobacterium to the body of sponges. In the experiment, gradual fouling of the primmorphs with cyanobacterium filaments, destruction of their structure and death of sponge cells were registered. In the control without addition of cyanobacteria, the primmorphs remained alive during the whole time of the experiment.

The paper presents the analysis of putatively complete and near-complete genomes of bacteriophages extracted from metagenomic data obtained from DNA samples isolated from Lake Baikal water using modern bioinformatic programs. A total of 73 sequences with lengths ranging from 13.8 kb to 163.7 kb belonging to phages of the Caudoviricetes class were identified. Two contigs belonging putatively to cyanophages with lengths of 36.8 kb and 163.7 kb were detected, and in the latter one an ORF with a length of 159 amino acid residues similar to the small heat shock protein (Hsp20) was identified. Analysis of the amino acid sequences identified in the assembled bacteriophage genomes using the PHROG database revealed that 27.5% of them have an unknown function, while the majority of those with similarity to known ones (23.7%) belong to the category “DNA, RNA and nucleotide metabolism”. A number of accessory metabolic genes (AMGs) were also detected in the assembled genomes: nadM, cysC, cobS, galE, cobT, etc. Most of the sequences with similarity to sequences from the IMG/VR database (89.6%) corresponded to sequences obtained from freshwater bodies.

An analysis of subfossil Cladocera in a 193-cm sediment core from Lake Beloe (Altai region) was conducted to trace the history of limnological conditions in the lake over the past 4600 years. Currently, a total of 34 Cladocera taxa were identified in the taphocenosis. The greatest cladoceran species richness was observed among littoral forms of Cladocera, reflecting the presence of shallow areas overgrown with macrophytes. The highest concentration of cladoceran remains was observed in the lower horizons of the core (150-191 cm, 3600-4600 cal yr BP). In this zone, the highest values of Hill indices are recorded, indicating high taxonomic diversity in the community. At a depth of 141 cm (3500 cal yr BP), significant changes in community structure occur, with Chydorus cf. sphaericus beginning to dominate. Taxonomic diversity of Cladocera noticeably increases in the upper part of the core.

This paper presents data on lake sediments that were selected from 5 lakes in Mongolia (10 points); the lakes are located at different absolute elevations above sea level. The purpose of this work is to study diatoms from surface bottom sediments (0-2 cm). In addition, the morphometric and physicochemical characteristics of the water in these lakes were studied. The water of the studied lakes was mainly ultra-fresh (40% of the lakes), the remaining 60% had fresh, slightly fresh and salt water (20% each). Such morphometric parameters as the area of the water surface, the length and width of the lake, the average width, the maximum depth and others were studied. As a result of studying the composition of diatoms, 111 species were identified that belong to 3 classes of Bacillariophyta. In terms of the number of species discovered, Lake Boon-Tsagan-Nuur turned out to be the richest. 10 species are classified as dominants, among them Staurosira venter can be distinguished; among the common species, Pseudostaurosira brevistriata stands out, which is dominant and subdominant in 5 samples; Stephanocyclus meneghinianus, Lindavia radiosa - dominants and subdominants in 4 samples. The diatom flora of the studied reservoirs shows that bottom forms predominate in the lakes.

In Lake Baikal, the number, diversity, and structure of femtoplankton – bacteria passing through filters with a 0.2 μm pore size – were studied for the first time using a complex of methods. The bacterial abundance in the femtoplankton fraction was 7×104 cells/mL in the 0-50 m water layer, as measured by epifluorescence microscopy, and their contribution to the total bacterial number reached an average of 4.4%. High-throughput sequencing of 16S rRNA gene fragments revealed a significant genetic and taxonomic diversity of femtobacterioplankton in the pelagic and littoral zones of the lake. Dominant and minor phyla, orders, families, genera, and phylotypes of bacteria were identified in two fractions of Lake Baikal bacterioplankton: larger and smaller than 0.2 µm. We determined the contribution of ultra-small bacteria to the taxonomic composition of microbial communities in different parts of the lake. The microbiomes of bacterioplankton and femtobacterioplankton fractions differed significantly, and we described the peculiarities of ultramicrobacteria composition. The results demonstrated an important role of ultra-small bacteria in Lake Baikal’s ecosystem.

For the first time, the composition of microbial communities in the sediments of the cold freshwater spring Churek-Dorgun, located in the Kaa-Khem district of the Republic of Tuva, was studied using high-throughput sequencing. According to the chemical composition, the water of the Churek-Dorgun spring belonged to the sulfate-hydrocarbonate calcium type with weak mineralization (0.39 g / L) and neutral pH values (6.8 - 7.3). According to the sequencing results, 38,066 reads of 16S rRNA gene belonging to the Bacteria and Archaea domains were identified in the sediments sample. Archaea accounted for 0.27% of the microorganisms, with the phylum Methanobacteriota predominating. In total, 23 phyla in the bacterial microbial community were identified. Three bacterial phyla - Pseudomonadota, Bacillota, and Bacteroidota - which are typical of freshwater microbial communities dominated. The basis of the silt microbial community was widespread widespread in different ecosystems microorganisms: Aeromonas, Psychrosinus, Malikia, Dechloromonas, Sunxiuqinia, Thiobacillus, Geobacter, Litorilinea, Giesbergeria and Rivibacter. They have different physiological properties and metabolism. Microorganisms involved in the sulfur cycle were also found in the silt, including chemolithotrophic sulfur-oxidizing bacteria of the genus Thiobacillus (class Betaproteobacteria, 3.02%), microaerophilic sulfur-reducing bacteria of the genus Geobacter (class Deltaproteobacteria, 2.86%), and sulfate-reducing Deltaproteobacteria.

The paper presents the results of a study of the reasons for the formation of biofilms during the purification of groundwater with use of natural sorbents. Analysis of the microbial complexes structure at different stages of water treatment showed that their numbers increased after filtration through a load with granular activated carbon. In some cases, it remained high in storage tanks containing purified water. In fact, at all stages of water treatment, representatives of Actinobacteria were found in the community structure, which formed biofilms in the technical system, as well as after 14 days of storage in bottled water. It was established that representatives of actinomycetes in the planktonic state formed flakes from mycelium, and on filter media they formed biofilms in the form of a complex structured community. Actinobacteria strains isolated from water and activated carbon biofilms differed in their cultural and morphological characteristics. However, they were characterized by a common ability to produce polymeric substances that formed a protective matrix and promoted cell adhesion to various substrates and surfaces. Scanning electron microscopy shown that sporulation promoted survival during all stages of groundwater treatment, including chlorination and ozonation.
