Metagenomic Analysis of Virioplankton from the Pelagic Zone of Lake Baikal.

This study describes two viral communities from the world's oldest lake, Lake Baikal. For the analysis, we chose under-ice and late spring periods of the year as the most productive for Lake Baikal. These periods show the maximum seasonal biomass of phytoplankton and bacterioplankton, which are targets for viruses, including bacteriophages.

DNA Binding to Gold Nanoparticles through the Prism of Molecular Selection: Sequence-Affinity Relation.

Native DNA strongly adsorbs to citrate-coated gold nanoparticles (AuNPs). The resulting composites (DNA/AuNPs) are valuable materials in many fields, especially in biomedicine. For this reason, the process of adsorption is a focus for intensive research.

Estimate of the diversity of viral and bacterial assemblage in the coastal water of Lake Baikal.

In this study, we analysed the diversity and composition of double-stranded DNA viral and bacterial communities within the sample of surface coastal water of Southern Baikal through metagenomics and deep sequencing of the 16S ribosomal RNA gene, respectively. The 16S rRNA gene analysis has revealed 14 phyla and dominance of the 'Actinobacteria' (43.6%), 'Proteobacteria' (25.

Assessing the diversity of the g23 gene of T4-like bacteriophages from Lake Baikal with high-throughput sequencing.

Based on second generation sequencing (MiSeq platform, Illumina), we determined the genetic diversity of T4-like bacteriophages of the family Myoviridae by analysing fragments of the major capsid protein gene g23 in the plankton of Lake Baikal. The sampling depth in our study was significantly higher than in those obtained by the Sanger method before. We obtained 33 701 sequences of the g23 gene fragments, 141 operational taxonomic units (OTUs) of which were identified.
