Methanogenium is a genus of archaeans in the family Methanomicrobiaceae. [1] The type species is Methanogenium cariaci. [2]
The species within Methanogenium are coccoid in shape and Gram-negatives and, like other methanogenic archaea, they produce methane from carbon dioxide, hydrogen or formate as substrates. [2] Although they occasionally have flagella, they are non-motile. They are strictly anaerobic, and can be found in marine and lake sediments that lack oxygen. [3]
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]

In taxonomy, the Thermoplasmata are a class of the Euryarchaeota.
Rubrobacter is a genus of Actinomycetota. It is radiotolerant and may rival Deinococcus radiodurans in this regard.
In the taxonomy of microorganisms, the Methanomicrobia are a class of the Euryarchaeota.
Methanospirillaceae are a family of microbes within Methanomicrobiales.
In taxonomy, Methanococcoides is a genus of the Methanosarcinaceae.
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, Methanohalophilus is a genus of the Methanosarcinaceae.
Halobiforma is a genus of halophilic archaea of the family Natrialbaceae.
In taxonomy, Haloplanus is a genus of the 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.
In taxonomy, Methanospirillum is a genus of microbes within the family Methanospirillaceae. All its species are methanogenic archaea. The cells are bar-shaped and form filaments. Most produce energy via the reduction of carbon dioxide with hydrogen, but some species can also use formate as a substrate. They are Gram-negative and move using archaella on the sides of the cells. They are strictly anaerobic, and they are found in wetland soil and anaerobic water treatment systems.
Methanocalculus is a genus of the Methanomicrobiales, and is known to include methanogens.
Phycisphaerae is a class of aquatic bacteria. They reproduce by budding and are found in samples of algae in marine water. Organisms in this group are spherical and have a holdfast, at the tip of a thin cylindrical extension from the cell body called the stalk, at the nonreproductive end that helps them to attach to each other during budding.
Syntrophomonas is a bacterial genus from the family of Syntrophomonadaceae.
Luteococcus is a bacterial genus from the family Propionibacteriaceae.
Marmoricola is a Gram-positive and chemoorganotrophic bacterial genus from the family of Nocardioidaceae.
Haloferacaceae is a family of halophilic, chemoorganotrophic or heterotrophic archaea within the order Haloferacales. The type genus of this family is Haloferax. Its biochemical characteristics are the same as the order Haloferacales.
Heliorestis is an alkaliphilic genus of bacteria from the family of Heliobacteriaceae.
