Polysaccharide-degrading archaea dominate acidic hot springs: genomic and cultivation insights into a novel <i>Thermoproteota</i> lineage Open
The expansion of sequencing technologies and bioinformatics has greatly advanced our understanding of microbial “dark matter,” yet the isolation of pure cultures, especially among Archaea, remains rare and challenging. Cultivation is still…

Microbial diversity of hot springs of the Kuril Islands Open
The Kuril Islands are located in the Far-East of Russia and enriched with shallow and terrestrial hot springs. Prokaryotic diversity of Kuril geothermal environments has been studied fragmentarily and mainly by culture-dependent methods. W…

Metagenomic Insights into the Taxonomic and Functional Features of Traditional Fermented Milk Products from Russia Open
Fermented milk products (FMPs) contain probiotics that are live bacteria considered to be beneficial to human health due to the production of various bioactive molecules. In this study, nine artisanal FMPs (kefir, ayran, khurunga, shubat, …

Water and Sediments of an Acidic Hot Spring—Distinct Differentiation with Regard to the Microbial Community Composition and Functions Open
Over the last half-century, microbial communities of the Kamchatka hot springs have been largely studied using molecular, radioisotopic, and cultural approaches. Generally, these results were obtained for mixed samples of water with sedime…

Fervidicoccus fontis Strain 3639Fd, the First Crenarchaeon Capable of Growth on Lipids Open
— Up to now, ability of prokaryotes to grow on lipids has been shown only for bacteria. Thermococcus sibiricus , member of the phylum Euryarchaeota isolated from a high-temperature oil well and capable of growth on olive oil, is the only e…

3C-seq-captured chromosome conformation of the hyperthermophilic archaeon <i>Thermofilum adornatum</i> Open
Three-dimensional structure of chromosomes displays diverse patterns across the tree of life, with compartments, interaction domains and loops being quite universally observed. The archaeal kingdom remains understudied to this extent so fa…
