An extremophile is an organism that is able to live in extreme environments, i.e. environments with conditions approaching or expanding the limits of what known life can adapt to, such as extreme temperature, radiation, salinity, or pH level.
Deinococcota is a phylum of bacteria with a single class, Deinococci, that are highly resistant to environmental hazards, also known as extremophiles. These bacteria have thick cell walls that give them gram-positive stains, but they include a second membrane and so are closer in structure to those of gram-negative bacteria.
Thermus aquaticus is a species of bacteria that can tolerate high temperatures, one of several thermophilic bacteria that belong to the Deinococcota phylum. It is the source of the heat-resistant enzyme Taq DNA polymerase, one of the most important enzymes in molecular biology because of its use in the polymerase chain reaction (PCR) DNA amplification technique.
Thermus is a genus of thermophilic bacteria. It is one of several bacteria belonging to the Deinococcota phylum. Thermus species can be distinguished from other genera in the family Thermaceae as well as all other bacteria by the presence of eight conserved signature indels (CSIs) found in proteins such as adenylate kinase and replicative DNA helicase as well as 14 conserved signature proteins (CSPs) that are exclusively shared by members of this genus.
Thermus thermophilus is a Gram-negative bacterium used in a range of biotechnological applications, including as a model organism for genetic manipulation, structural genomics, and systems biology. The bacterium is extremely thermophilic, with an optimal growth temperature of about 65 °C (149 °F). Thermus thermophilus was originally isolated from a thermal vent within a hot spring in Izu, Japan by Tairo Oshima and Kazutomo Imahori. The organism has also been found to be important in the degradation of organic materials in the thermogenic phase of composting. T. thermophilus is classified into several strains, of which HB8 and HB27 are the most commonly used in laboratory environments. Genome analyses of these strains were independently completed in 2004. Thermus also displays the highest frequencies of natural transformation known to date.
Thermococcus celer is a Gram-negative, spherical-shaped archaeon of the genus Thermococcus. The discovery of T. celer played an important role in rerooting the tree of life when T. celer was found to be more closely related to methanogenic Archaea than to other phenotypically similar thermophilic species. T. celer was the first archaeon discovered to house a circularized genome. Several type strains of T. celer have been identified: Vu13, ATCC 35543, and DSM 2476.
Glucosyl-3-phosphoglycerate phosphatase (EC 3.1.3.85, GpgP protein) is an enzyme with systematic name α-D-glucosyl-3-phospho-D-glycerate phosphohydrolase. This enzyme catalyses the following chemical reaction
Psychrobacter cryohalolentis is a Gram-negative, nonmotile species of bacteria. It was first isolated from Siberian permafrost. Its type strain is K5T.
Psychrobacter arcticus is a Gram-negative, nonmotile species of bacteria first isolated from Siberian permafrost. Its type strain is 273-4T.
Deinococcus geothermalis is a non-pathogenic, sphere-shaped, Gram-positive, heterotrophic bacterium, where geothermalis means 'hot earth' or 'hot springs'. This bacterium was first obtained from the hot springs of Agnano, Naples, Italy and São Pedro do Sul, Portugal.
Deinococcus murrayi is a bacterium. It produces orange-pigmented colonies and has an optimum growth temperature of about 45 °C (113 °F) to 50 °C (122 °F). It is extremely gamma radiation-resistant. Its type strain is ALT-1b.
Methanomethylovorans thermophila is a species of thermophilic, methylotrophic methanogenic microbe. It is Gram-negative, and its type strain is L2FAWT. It was isolated from an anaerobic reactor in a laboratory. Its cells are Gram-negative, non-motile, and coccoid in form. It has been found to use methanol and methyl amines as substrates in the production of methane. It cannot use formiate, carbon dioxide with hydrogen, acetate, dimethyl sulfide, methanethiol, or propanol. As its name suggests, it is a thermophile, with an optimal growth temperature of 50 °C.
Persephonella marina is a Gram-negative, rod shaped bacteria that is a member of the Aquificota phylum. Stemming from Greek, the name Persephonella is based upon the mythological goddess Persephone. Marina stems from a Latin origin, meaning "belonging to the sea". It is a thermophile with an obligate chemolithoautotrophic metabolism. Growth of P. marina can occur in pairs or individually, but is rarely seen aggregating in large groups. The organism resides on sulfidic chimneys in the deep ocean and has never been documented as a pathogen.
Thermoclostridium stercorarium is a cellulolytic thermophilic bacterium. It is anaerobic, spore-forming and saccharoclastic, with cells being rod-shaped and 0.7 to 0.8 by 2.7 to 7.7 µm in size. Its genome has been sequenced.
Thermoanaerobacter siderophilus is a dissimilatory Fe(III)-reducing, anaerobic, thermophilic bacterium that was firstly isolated from the sediment of a hydrothermal vent found near the Karymsky volcano, in the Kamchatka peninsula, Russia. It is spore-forming, with type strain SR4T.
Thermococcus barophilus is a piezophilic and hyperthermophilic archaeon isolated from a deep-sea hydrothermal vent. It is anaerobic and sulfur-metabolising, with type strain MPT.
