Methanococci is a class of methanogenic archaea in the phylum Euryarchaeota. [1] They can be mesophilic, thermophilic or hyperthermophilic.
Euryarchaeota is a phylum of archaea. Euryarchaeota are highly diverse and include methanogens, which produce methane and are often found in intestines, halobacteria, which survive extreme concentrations of salt, and some extremely thermophilic aerobes and anaerobes, which generally live at temperatures between 41 and 122 °C. They are separated from the other archaeans based mainly on rRNA sequences and their unique DNA polymerase.
The Thermoprotei is a class of the Thermoproteota.
In taxonomy, the Methanopyri are a class of the Euryarchaeota.
In taxonomy, the Thermoplasmata are a class of the Euryarchaeota.
In taxonomy, the Thermoplasmataceae are a family of the Thermoplasmatales. It contains only one genus, Thermoplasma. All species within Thermoplasmataceae are thermoacidophiles, and they grow at a temperature of 60 °C and pH 2. They were isolated from hydrothermal vents, fumaroles and similar environments.
In taxonomy, the Thermoplasmatales are an order of the Thermoplasmata. All are acidophiles, growing optimally at pH below 2. Picrophilus is currently the most acidophilic of all known organisms, being capable of growing at a pH of -0.06. Many of these organisms do not contain a cell wall, although this is not true in the case of Picrophilus. Most members of the Thermotoplasmata are thermophilic.
Methanobacteria is a class of archaeans in the kingdom Euryarchaeota. Several of the classes of the Euryarchaeota are methanogens and the Methanobacteria are one of these classes.
In taxonomy, the Thermococci are a class of microbes within the Euryarchaeota.
In the taxonomy of microorganisms, the Methanomicrobia are a class of the Euryarchaeota.
The Cenarchaeales are an order of the Thermoproteota, a phylum of Archaea.
The Desulfurococcales is an order of the Thermoprotei, part of the kingdom Archaea. The order encompasses some genera which are all thermophilic, autotrophs which utilise chemical energy, typically by reducing sulfur compounds using hydrogen. Desulfurococcales cells are either regular or irregular coccus in shape, with forms of either discs or dishes. These cells can be single, in pairs, in short chains, or in aciniform formation.
In taxonomy, the Methanococcales are an order of the Methanococci.
Methanosarcinales is an order of archaeans in the class Methanomicrobia.
In taxonomy, the Methanosaetaceae are a family of microbes within the order Methanosarcinales. All species within this family use acetate as their sole source of energy.
In taxonomy, the Methanosarcinaceae are a family of the Methanosarcinales.
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.
In taxonomy, Dinoroseobacter is a genus of the Rhodobacteraceae.
Aciduliprofundum is a genus of the Euryarchaeota.
In taxonomy, Methanotorris is a genus of the Methanocaldococcaceae. 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.
In taxonomy, Methanothermococcus is a genus of the Methanococcaceae. The cells are shaped like irregular bars and tend to be Gram-negative. They are mobile via polar flagella. They require acetate to grow.
