Methanococci is a class of methanogenic archaea in the phylum Euryarchaeota. [1] They can be mesophilic, thermophilic or hyperthermophilic.

Methanococcus is a genus of coccoid methanogens of the family Methanococcaceae. [1] . They are all mesophiles, except the thermophilic M. thermolithotrophicus and the hyperthermophilic M. jannaschii.

Methanococcus is a genus of well-characterized mesophilic and hydrogenotrophic methanogens with a robust genetic system. Commonly found in tidal marshes, they compete with sulfate- and iron-reducing bacteria for hydrogen gas (H 2) and formate, their two major energy sources.

Jun 10, 2016 · Methanococcus maripaludis is a rapidly growing, fully sequenced, genetically tractable model organism among hydrogenotrophic methanogens. It has the ability to convert CO 2 and H 2 into a useful cleaner energy fuel (CH 4). In fact, this conversion enhances in the presence of free nitrogen as the sole nitrogen source due to prolonged cell growth.

Jan 1, 2023 · Methanococcus is a genus of well-characterized mesophilic and hydrogenotrophic methanogens with a robust genetic system. Commonly found in tidal marshes, they compete with sulfate- and iron-reducing bacteria for hydrogen gas (H …

Methanocaldococcus formerly known as Methanococcus is a genus of coccoid methanogen archaea. [1] . They are all mesophiles, except the thermophilic M. thermolithotrophicus and the hyperthermophilic M. jannaschii.

Mar 5, 2021 · Hyperthermophilic Methanococci are high-pressure CH 4 production cell factories and the addition of cysteine and a rich TES in the media are essential for efficient growth of these Methanococci.

Methanococcus maripaludis is a rapid growing hydrogenotrophic methanoarchaeon common in salt marshes, marine and estuarine environments in the Southeastern U.S.A. and probably elsewhere. It is obligately methanogenic; H 2 and formate serve as electron donors. Acetate, methanol and methylamines are not substrates for methanogenesis.

Members of the Methanococcales (the methanococci) are coccoid methanogens isolated from marine environments. They share a set of phenotypic characteristics. They all use H 2 or formate to reduce CO 2 for methanogenesis. Acetate, methyl-containing compounds, and alcohols are not used as substrates for methanogenesis.

Oct 19, 2014 · As of December 2013 these genera contained 4 and 2 species, respectively. This family of mesophilic or thermophilic and neutrophilic methanogens belongs to the order Methanococcales. The members are coccoid in shape, motile, and have a generation time of less than 3 h under optimal conditions.
