From 24 samples of hydrothermal venting structures collected at the East Pacific Rise (13 degrees N), 13 enrichments of coccoid cells were obtained which grew on CO, producing H2 and CO2 at 80 degrees C. A hyperthermophilic archaeon capable of lithotrophic growth on CO coupled with equimolar production of H2 was isolated. Based on its 16S rRNA sequence(More)
A novel anaerobic, thermophilic, alkalitolerant bacterium, strain 2204(T), was isolated from a hot spring of the Baikal Lake region. The cells of strain 2204(T) were straight rods of variable length, Gram-positive with an S-layer, motile with one to two lateral flagella, and often formed aggregates of 3-15 cells. The isolate was shown to be an obligate(More)
An obligately anaerobic, hyperthermophilic, organoheterotrophic archaeon, strain Z-1312(T), was isolated from a freshwater hot spring of the Uzon caldera (Kamchatka Peninsula, Russia). The cells were regular cocci, 1-4 microm in diameter, with one long flagellum. The cell envelope was composed of a globular layer attached to the cytoplasmic membrane. The(More)
Detection and analysis of the mcrA gene encoding methyl-coenzyme M reductase, the key enzyme of methanogenesis, was used to assess occurrence and diversity of methanogenic archaea in terrestrial hot springs of Kamchatka and Sa~o Miguel Island (the Azores). For this analysis, phylogeny of methanogens was initially reconstructed based on available sequences(More)
The goal of this work was to study the diversity of microorganisms inhabiting a deep subsurface aquifer system in order to understand their functional roles and interspecies relations formed in the course of buried organic matter degradation. A microbial community of a deep subsurface thermal aquifer in the Tomsk Region, Western Siberia was monitored over(More)
