A novel moderately thermophilic, facultatively anaerobic chemoorganotrophic bacterium strain P3M-2(T) was isolated from a microbial mat developing on the wooden surface of chute under flow hot water (46°C) coming out 2775-m-deep oil exploration well (Tomsk region, Russia). Strain is moderate thermophile and facultative anaerobe growing mono-, di- or polysaccharides by aerobic respiration, fermentation reducing diverse electron acceptors [nitrite, Fe(III), As(V)]. Its closest cultivated...
A novel obligately anaerobic, mesophilic, organotrophic bacterium, strain P3M-1 T , was isolated from a microbial mat formed in wooden bath filled with hot water emerging 2775 m-deep well the Tomsk region of western Siberia, Russia. Cells were rod-shaped, 0.3–0.7 µm width and multicellullar filaments that reached up to 400 length. Strain grew optimally at 42–45 °C, pH 7.5–8.0, 0.1% (w/v) NaCl. Under optimal conditions, doubling time 6 h. The isolate able ferment variety proteinaceous...
Akkermansia muciniphila is a gram-negative anaerobic bacterium, which represents part of the commensal human microbiota. Decline in abundance A. among other microbial species gut correlates with severe systemic diseases such as diabetes, obesity, intestinal inflammation and colorectal cancer. Due to its mucin-reducing immunomodulatory properties, use probiotics containing sp. appears promising approach treatment metabolic inflammatory diseases. In particular, number studies have focused on...
Melioribacter roseus is a moderately thermophilic facultatively anaerobic organotrophic bacterium representing novel deep branch within Bacteriodetes/Chlorobi group. To better understand the metabolic capabilities and possible ecological functions of M. get insights into evolutionary history this bacterial lineage, we sequenced genome type strain P3M-2(T). A total 2838 open reading frames was predicted from its 3.30 Mb genome. The whole proteome analysis supported phylum-level classification...
A novel strictly anaerobic, halotolerant, organotrophic bacterium, strain P3M-3(T), was isolated from a microbial mat formed under the flow of hot water emerging 2775 m-deep well in Tomsk region (western Siberia, Russia). Cells P3M-3(T) were straight and curved rods, 0.2-0.4 µm width 1.5-20 length. Strain grew optimally at 37 °C, pH 7.0-7.5 NaCl concentration 15 g l(-1). Under optimum growth conditions, doubling time 1 h. The isolate able to ferment variety mono-, di- polysaccharides,...
The goal of this work was to study the diversity microorganisms inhabiting a deep subsurface aquifer system in order understand their functional roles and interspecies relations formed course buried organic matter degradation. A microbial community thermal Tomsk Region, Western Siberia monitored over five years via 2.7 km borehole 3P, drilled down Palaeozoic basement. water discharges with temperature ca. 50oC. Its chemical composition varies, but it steadily contains acetate, propionate,...
A novel obligately anaerobic, extremely thermophilic, organotrophic bacterium, strain 1445t(T), was isolated from a hot spring on Kunashir Island (Kuril Islands, Russia). Cells were motile rods (0.4-0.5 × 1.0-3.0 µm). The temperature range for growth at pH 7.8 46-80 °C, with optimum 65 °C. °C 5.7-9.0, 7.8. Growth not observed or below 40 above 84 5.4 9.5. isolate degraded wide of substrates including starch, cellulose and derivatives. Elemental sulfur stimulated growth, but sodium sulfate,...
A novel hyperthermophilic, anaerobic filamentous archaeon, Thermofilum adornatum strain 1910b T , is capable of growing with cellulose as its sole carbon and energy source. This was isolated from a terrestrial hot spring in Kamchatka, Russia. The isolate 1910bT grew optimally at temperature 80°C pH 5.5-6.0, producing cell-bound inducible cellulases. During genome analysis, genes, encoding various glycosidases (GHs) involved oligo-and polysaccharide hydrolysis genes for the fermentation...
Abstract A strain of a hyperthermophilic filamentous archaeon was isolated from sample Kamchatka hot spring sediment. Isolate 1807-2 grew optimally at 85 °C, pH 6.0-6.5, the parameters being close to those sampling site. 16S rRNA gene sequence analysis placed novel isolate in crenarchaeal genus Thermofilum ; pendens its closest valid relative (95.7 % identity). Strain organothrophically using polysaccharides (starch and glucomannan), yeast extract or peptone as substrates. The addition other...
A novel obligately anaerobic, extremely thermophilic, organotrophic bacterium, strain ik275mar(T), was isolated from a Mid-Atlantic Ridge deep-sea hydrothermal vent. Cells were rods surrounded by sheath-like structure (toga), 0.4-0.9 µm in width and 1.2-6.0 length. Strain ik275mar(T) grew at 37-75 °C, pH 5.6-8.2 NaCl concentrations of 10-55 g l(-1). Under optimum conditions (70 6.6, 20 l(-1)), doubling time 32 min. The isolate able to ferment carbohydrates including starch, cellulose...
The Yessentuki mineral water deposit (YMWD) is a well-known source of balneologically valuable drinking water, but it has rarely been investigated in terms the microbes inhabiting it. In this work, we have studied microbial communities continuously operating production well 9, penetrating Lower Cretaceous aquifer YMWD, and characterized, detail, two novel representatives class Ignavibacteria (Bacteroidota). One representative so-called XYB12-FULL-38-5 group within family Melioribacteraceae...
A novel obligately anaerobic, extremely thermophilic, organotrophic bacterium, strain Rift-s3(T), was isolated from a deep-sea sample containing Riftia pachyptila sheath Guaymas Basin, Gulf of California. Cells the isolate were rods, 0.3-0.8 µm in width and 1.5-10 length, surrounded by sheath-like structure (toga).
