WebHyperthermophilic methanogens and H 2 -producing heterotrophs are collocated in high-temperature subseafloor environments, such as petroleum reservoirs, mid-ocean ridge flanks, and hydrothermal vents. Web15 okt. 2001 · Many archaea colonize extreme environments. They include hyperthermophiles, sulfur-metabolizing thermophiles, extreme halophiles and methanogens. Because extremophilic microorganisms have unusual properties, they are a potentially valuable resource in the development of novel biotechnological processes. Despite …

Web1 mrt. 2002 · Most hyperthermophiles that have been isolated and characterized are members of the Archaea and are anaerobes [ 4 ]. As the solubility of oxygen in aqueous systems declines rapidly with increasing temperature it is not surprising that organisms isolated from hot springs and thermal vents are anaerobes. A hyperthermophile is an organism that thrives in extremely hot environments—from 60 °C (140 °F) upwards. An optimal temperature for the existence of hyperthermophiles is often above 80 °C (176 °F). Hyperthermophiles are often within the domain Archaea, although some bacteria are also able … Meer weergeven Hyperthermophiles isolated from hot springs in Yellowstone National Park were first reported by Thomas D. Brock in 1965. Since then, more than 70 species have been established. The most extreme hyperthermophiles … Meer weergeven Early research into hyperthermophiles speculated that their genome could be characterized by high guanine-cytosine content; however, recent studies show that "there is no obvious correlation between the GC content of the genome and the optimal … Meer weergeven Archaea • Strain 121, an archaeon living at 121 °C in the Pacific Ocean. • Pyrolobus fumarii, an archaeon living at 113 °C in Atlantic hydrothermal vents. • Pyrococcus furiosus, an archaeon which thrives at 100 °C, first discovered … Meer weergeven Stetter, Karl (Feb 2013).
