A novel moderately thermophilic, microaerobic to anaerobic, chemolithoautotrophic bacterium, designated strain CRT, was isolated from a deep-sea hydrothermal vent site at 36 degrees N on the Mid-Atlantic Ridge. Cells were Gram-negative, non-motile rods. The organism grew at 45-65 degrees C and pH 6.5-7.4, with optimum growth at 55 degrees C and pH 6.9-7.1.(More)
A thermophilic, anaerobic, piezophilic, chemo-organotrophic sulfur-reducing bacterium, designated as KA3T, was isolated from a deep-sea hydrothermal chimney sample collected at a depth of 2630 m on the East-Pacific Rise (13 degrees N). When grown under elevated hydrostatic pressure, the cells are rod-shaped with a sheath-like outer structure, motile, have a(More)
Bourlyashchy is the largest and hottest pool in the Uzon Caldera, located in the territory of Kronotsky Nature Reserve, Kamchatka, Russia, with sediment surface temperatures at the margins ranging from 86 to 97 °C, and pH from 6.0 to 7.0. The microbial communities of the pool water and sediments were studied comprehensively from 2005 to 2014. Radioisotopic(More)
A novel, strictly anaerobic, thermophilic sulfur-reducing bacterium, strain 525T, was isolated from tubes of the deep-sea hydrothermal vent polychaete Alvinella pompejana, collected on the East Pacific Rise (13 degrees N). This organism grew in the temperature range 37-68 degrees C, the optimum being 53 degrees C, and in the pH range 6.4-7.4, the optimum(More)
