Methanobacteriati

Methanoregula is a genus of archaeans in the order Methanomicrobiales. It was isolated from an acidic peat bog. It produces methane at the lowest pH of any known organism.

Methanocaldococcaceae is 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.

thermophilic methanogenic archaeon

Picrophilaceae is a family of microbes within the order Thermoplasmatales.

species of archea

Methanospirillaceae is a family of microbes within the order Methanomicrobiales.

Acidiplasma is a genus in the phylum Euryarchaeota (Archaea).

Methanomethylovorans is a genus of microorganisms in 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.

Methanosaetaceae is a family of microbes within the order Methanosarcinales. All species within this family use acetate as their sole source of energy.

Methanothermaceae are a family of microbes within the order Methanobacteriales.

species of hyperthermophilic anaerobic archaeon

Methanobacteriati (formerly "Euryarchaeota", from Ancient Greek εὐρύς eurús, "broad, wide") is a kingdom of archaea. Methanobacteriati 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 only validly published name for this group under the Prokaryotic Code is

a sulfate-reducing archeon

Methanothermococcus is a genus of archaeans in the family 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.

Methanocalculus is a genus of archaeans in the order Methanomicrobiales, and is known to include methanogens.

Hadesarchaea, formerly called the South-African Gold Mine Miscellaneous Euryarchaeal Group, is a class of thermophile microorganisms that have been found in deep mines, hot springs, marine sediments, and other subterranean environments.

Methanotorris is a genus of archaeans in the family 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.

Methanosalsum is a genus of microbes within the family Methanosarcinaceae. This genus contains two species.

Palaeococcus is a genus of archaeans in the family Thermococcaceae.

The genus Methanimicrococcus was described based on the strain PA (ATCC BAA-276; DSM 13328), isolated from the hindgut of a cockroach, Periplaneta americana. The species was initially named Methanomicrococcus blatticola; however, the name was later corrected to Methanimicrococcus blatticola, making it the only genus of methanogens that has -i as a connecting vowel rather than -o in the name.
