Thermotolerant and thermophilic actinomycetes from soils of Mongolia desert steppe zone
Molecular biological investigation of the samples of desert steppe soils by denaturing gradient gel electrophoresis and fluorescent in situ hybridization revealed members of the phylum Actinobacteria and FISH analysis revealed that the biomass of the metabolically active mycelial actinob bacteria in the prokaryotic community of Mongolian desert soils exceeded that of the unicellular ActInobacteria.

Methane oxidation activity and diversity of aerobic methanotrophs in pH-neutral and semi-neutral thermal springs of the Kunashir Island, Russian Far East
The results suggest that methanotrophs inhabiting thermal springs with temperature exceeding 50 °C may represent novel thermophilic and thermotolerant species of the genera Methylocystis and Methylothermus, as well as previously undescribed Gammaproteobacteria. Expand
Molecular analysis of high-affinity methane-oxidizing enrichment cultures isolated from a forest biocenosis and agrocenoses
Methane oxidation by microorganisms inhabiting aerobic soils is a key process involved in the regulation of the concentration of this significant greenhouse gas in the atmosphere; however, theExpand
Biological activity of alpine mountain-meadow soils in the Teberda Reserve
The intensity of the actual and potential CO2 emissions, nitrogen fixation, denitrification, and methane production were determined by gas chromatography in alpine mountain-meadow soils underExpand
Aerobic Methanotrophs in Natural and Agricultural Soils of European Russia
Using a culture-independent approach targeting pmoA gene, the first baseline data on the diversity of methanotrophs inhabiting most typical soil types is provided, suggesting that soil restoration may have a positive effect on methane consumption by terrestrial ecosystems. Expand
A hydrocarbon-oxidizing acidophilic thermotolerant bacterial association from sulfur blocks
A stable bacterial association isolated from a sulfur block sample of the Astrakhan gas processing complex was able to utilize n-alkanes as the sole carbon and energy source at low pH, suggesting that this bacterial association is a unique microbial community, in which development of acidophilic hydrocarbon-oxidizing bacteria is mediated by a localized pH decrease in the sulfur blocks resulting from elemental sulfur oxidation.

Effect of Complex Microbial Inoculants on the Number and Diversity of Rhizospheric Microorganisms and the Yield of Soybean
Results showed that Ecovital application (co-inoculation with Bradyrhizobium and Bacillus strains) significantly improves soybean yield and soil fertility, as compare with inoculation by B. japonicum singly. Expand
Xanthobacter xylophilus sp. nov., a member of the xylotrophic mycobacterial community of low-mineral oligotrophic waters
The genetic and ecophysiological properties of strain Z-0055 support classification of this acid-tolerant inhabitant of oligotrophic waters within the genus Xanthobacter as a new species X. nov. Expand
Nitrogen fixation as a possible physiological basis of coprophagy in pikas (Ochotona, Lagomorpha, Mammalia)
Two families of the order Lagomorpha, Ochoto� nidae, and Leporidae, are characterized by a peculiar dietary adaptation, i.e., obligate autocoprophagy. The animal produces excrement of two types:Expand
Ancylobacter abiegnus sp. nov., an oligotrophic member of the xylotrophic mycobacterial community
The phenotypic and phylogenetic properties of strain Z-0056 support classification of this microorganism within the genus Ancylobacter as the novel species An cylinderobacter abiegnus sp. Expand
