Methanococcaceae
In taxonomy, the Methanococcaceae are a family of the Methanococcales. These organisms produce methane from formate or through the reduction of carbon dioxide with hydrogen. They live in marshes and other coastal areas. Members of the genus ''Methanothermococcus'' have been found in deep-sea hydrothermal vents.

Methanococcus Aeolicus
''Methanococcus'' is a genus of coccoid methanogens of the family Methanococcaceae. They are all mesophiles, except the thermophilic '' M. thermolithotrophicus'' and the hyperthermophilic '' M. jannaschii''. The latter was discovered at the base of a “white smoker” chimney at 21° N on the East Pacific Rise and it was the first archaeal genome to be completely sequenced, revealing many novel and eukaryote-like elements.

List Of Archaea Genera
This article lists the genera of the Archaea. The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI). Phylogeny National Center for Biotechnology Information (NCBI) taxonomy was initially used to decorate the genome tree via tax2tree. The 16S rRNA-based Greengenes taxonomy is used to supplement the taxonomy particularly in regions of the tree with no cultured representatives. List of Prokaryotic names with Standing in Nomenclature (LPSN) is used as the primary taxonomic authority for establishing naming priorities. Taxonomic ranks are normalised using phylorank and the taxonomy manually curated to remove polyphyletic groups. Cladogram was taken from the GTDB release 07-RS207 (8th April 2022). The position of clades with a "question mark" are based on the additional phylogeny of the 16S rRNA-based LTP_12_2021 by The All-Species Living Tree Project. Phylum " Altarcha ...

Methanocaldococcaceae
In taxonomy, the Methanocaldococcaceae are a family of microbes within the order Methanococcales. It contains two genera, the type genus ''Methanocaldococcus'' and ''Methanotorris''. These species are coccoid in form, neutrophilic to slightly acidophilic, and predominantly motile, and they have a very short generation period, from 25 to 45 minutes under optimal conditions. They produce energy exclusively through the reduction of carbon dioxide with hydrogen. Some species have been found in marine hydrothermal vents.

Methanothermococcus Okinawensis
''Methanothermococcus okinawensis'' is a thermophilic, methane-producing archaeon first isolated from deep-sea hydrothermal vent on the western Pacific Ocean. Its cells are highly motile, irregular cocci, with a polar bundle of flagella. Its type strain is IH1T (=JCM 11175T =DSM 14208T). It grows at an optimal temperature of 60–65 °C and pH of 6.7. It is strictly anaerobic and reduces carbon dioxide with hydrogen to produce methane, but it can also use formate. Research studies indicate that it might be able to survive extreme conditions in solar system's other bodies, such as Saturn's moon Enceladus. See also * Methanogens Methanogens are microorganisms that produce methane as a metabolic byproduct in hypoxic conditions. They are prokaryotic and belong to the domain Archaea. All known methanogens are members of the archaeal phylum Euryarchaeota. Methanogens are co ...

Archaea
Archaea ( ; singular archaeon ) is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this term has fallen out of use. Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla. Classification is difficult because most have not been isolated in a laboratory and have been detected only by their gene sequences in environmental samples. Archaea and bacteria are generally similar in size and shape, although a few archaea have very different shapes, such as the flat, square cells of ''Haloquadratum walsbyi''. Despite this morphological similarity to bacteria, archaea possess genes and several metabolic pathways that are more closely related to those of eukaryotes, notably for the enzymes involved ...

Hydrothermal Vents
A hydrothermal vent is a fissure on the seabed from which geothermally heated water discharges. They are commonly found near volcanically active places, areas where tectonic plates are moving apart at mid-ocean ridges, ocean basins, and hotspots. Hydrothermal deposits are rocks and mineral ore deposits formed by the action of hydrothermal vents. Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Under the sea, they may form features called black smokers or white smokers. Relative to the majority of the deep sea, the areas around hydrothermal vents are biologically more productive, often hosting complex communities fueled by the chemicals dissolved in the vent fluids. Chemosynthetic bacteria and Archaea form the base of the food chain, supporting diverse organisms, including giant tube worms, clams, limpets and shrimp. Active hydrothermal vents are thought to exist on Jupiter's moon Europa an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methanotorris
In taxonomy, ''Methanotorris'' is a genus of the Methanocaldococcaceae.See the NCBIbr>webpage on Methanotorris Data extracted from the The organisms in this genus differ from those of ''Methanothermococcus'' in that they are hyperthermophiles and from those of Methanocaldococcus in that they have no flagella, are not motile, and do not require selenium to grow. These microbes have not been shown to cause any illnesses. Nomenclature The name "Methanotorris" comes from the Latin ''methanum'' for methane Methane ( , ) is a chemical compound with the chemical formula (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The relative abundance of methane on Ea ... and ''torris'' for fire.

Methanocaldococcus
''Methanocaldococcus'' formerly known as ''Methanococcus'' is a genus of coccoid methanogen archaea. They are all mesophiles, except the thermophilic ''M. thermolithotrophicus'' and the hyperthermophilic ''M. jannaschii''. The latter was discovered at the base of a “white smoker” chimney at 21° N on the East Pacific Rise and it was the first archaean genome to be completely sequenced, revealing many novel and eukaryote-like elements. Nomenclature The name ''Methanocaldococcus'' has Latin and Greek roots, ''methano'' for methane, ''caldo'' for hot, and the Greek ''kokkos'' for the spherical shape of the cells. Overall, the name means ''spherical cell that produces methane at hot temperatures''. Metabolism All species in ''Methanocaldococcus'' are obligate methanogens. They use hydrogen to reduce carbon dioxide. Unlike many other species within Euryarchaeota, they cannot use formate, acetate, methanol or methylamines as substrates.
