Species

In taxonomy, Methanococcoides is a genus of the Methanosarcinaceae. [1]

Contents

Methanococcoides species are methanogens entirely dependent on methylated compounds for nutrition. The type species of Methanococcoides is Methanococcoides methylutens. [2] [3]

Phylogeny

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [4] and National Center for Biotechnology Information (NCBI). [1]

The Coriobacteriales are an order of Actinomycetota.

Eggerthella is a bacterial genus of Actinomycetota, in the family Coriobacteriaceae. Members of this genus are anaerobic, non-sporulating, non-motile, Gram-positive bacilli that grow singly, as pairs, or in short chains. They are found in the human colon and feces and have been implicated as a cause of ulcerative colitis, liver and anal abscesses and systemic bacteremia.

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 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.

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.

Acidilobus is a genus of archaea in the family Acidilobaceae.

In taxonomy, Methanimicrococcus is a genus of the Methanosarcinaceae. The members of this genus have been found in pharmaceutical wastewater, and they can contribute to the degradation of organic contaminants.

In taxonomy, Methanohalobium is a genus of the Methanosarcinaceae. Its genome has been sequenced. The genus contains one species, M. evestigatum.

<i>Methanohalophilus</i> Genus of archaea

In taxonomy, Methanohalophilus is a genus of the Methanosarcinaceae.

In taxonomy, Methanolobus is a genus of methanogenic archaea within the Methanosarcinaceae. These organisms are strictly anaerobes and live exclusively through the production of methane, but the species within Methanolobus cannot use carbon dioxide with hydrogen, acetate or formate, only methyl compounds. The cells are irregular coccoid in form and approximately 1 μm in diameter. They do not form endospores. They are Gram negative and only some are motile, via a single flagellum. They are found in lake and ocean sediments that lack oxygen.

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.

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.
