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.
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 taxonomy, the Methanococcales are an order of the Methanococci.
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.
Methanomicrobiaceae are a family of archaea in the order the Methanomicrobiales.
In taxonomy, the Methanosarcinaceae are a family of the Methanosarcinales.
Methanogenium is a genus of archaeans in the family Methanomicrobiaceae. The type species is Methanogenium cariaci.
In taxonomy, Methanococcoides is a genus of the Methanosarcinaceae.
In taxonomy, Methanohalobium is a genus of the Methanosarcinaceae. Its genome has been sequenced. The genus contains one species, M. evestigatum.
In taxonomy, Methanohalophilus is a genus of the Methanosarcinaceae.
In taxonomy, Methanomethylovorans is a genus of microorganisms with the family Methanosarcinaceae. This genus was first described in 1999. The species within it generally live in freshwater environments, including rice paddies, freshwater sediments and contaminated soil. They produce methane from methanol, methylamines, dimethyl sulfide and methanethiol. With the exception of M. thermophila, which has an optimal growth temperature of 50 °C, these species are mesophiles and do not tend to grow at temperatures above 40 °C.
In taxonomy, Methanosalsum is a genus of microbes within the family Methanosarcinaceae. This genus contains two species.
Natronorubrum is a genus in the family Halobacteriaceae.
In taxonomy, Methanocorpusculum is a genus of microbes within the family Methanocorpusculaceae. The species within Methanocorpusculum were first isolated from biodisgester wastewater and activated sludge from anaerobic digestors. In nature, they live in freshwater environments. Unlike most other methanogenic archaea, they do not require high temperatures or extreme salt concentrations to live and grow.
Methanoculleus is a genus of microbes within the family Methanomicrobiaceae. The species of the genus Methanoculleus live in marine environments brackish water, and are very common in bioreactors, landfills, and wastewater. Unlike other archaea, Methanoculleus and some species of related genera can use ethanol and some secondary alcohols as electron donors as they produce methane. This has implications as the production of methane as a greenhouse gas and consequences with respect to global climate change.
In taxonomy, Methanofollis is a genus of the Methanomicrobiaceae.
Methanocalculus is a genus of the Methanomicrobiales, and is known to include methanogens.
