The Thermoprotei is a class of the Thermoproteota.
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.
In the taxonomy of microorganisms, the Methanomicrobia are a class of the Euryarchaeota.
Acidilobales are an order of archaea in the class Thermoprotei.
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.
Methanobacteriales is an order of archaeans in the class Methanobacteria. Species within this order differ from other methanogens in that they can use fewer catabolic substrates and have distinct morphological characteristics, lipid compositions, and RNA sequences. Their cell walls are composed of pseudomurein. Most species are Gram-positive with rod-shaped bodies and some can form long filaments. Most of them use formate to reduce carbon dioxide, but those of the genus Methanosphaera use hydrogen to reduce methanol to methane.
In the taxonomy of microorganisms, the Methanomicrobiales are an order of the Methanomicrobia. Methanomicrobiales are strictly carbon dioxide reducing methanogens, using hydrogen or formate as the reducing agent. As seen from the phylogenetic tree based on 'The All-Species Living Tree' Project the family Methanomicrobiaceae is highly polyphyletic within the Methanomicrobiales.
Sulfolobales is an order of archaeans in the class Thermoprotei.
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.
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.
In taxonomy, the Methanocorpusculaceae are a family of microbes within the order Methanomicrobiales. It contains exactly one genus, Methanocorpusculum. The species within Methanocorpusculum were first isolated from anaerobic digesters and anaerobic wastewater treatment plants. In the wild, they prefer freshwater environments. Unlike many other methanogenic archaea, they do not require high temperatures or extreme salt concentrations to live and grow.
