Antonie van Leeuwenhoek, 1994
Methanogenic archaea convert a few simple compounds such as H2 + CO2, formate, methanol, methylamines, and acetate to methane. Methanogenesis from all these substrates requires a number of unique coenzymes, some of which are exclusively found in methanogens.

Methanogenic Fermentation of Benzoate
Journal of Bacteriology, 1969A methanogenic enrichment culture decomposed small concentrations of 14 C-benzoate to 14 C 4 and 14 CO 2 under stringently anaerobic conditions with or without preceding exposure to benzoate.

Molecular Biology of Methanogens
Annual Review of Microbiology, 1992Methanogens are a very diverse group of the Archaea (Archaebacteria). Their genomic DNAs range from 26 to 68 mol% G+C; they exhibit all known prokaryotic morphologies and inhabit anaerobic environments as varied as the human gut and deep-sea volcanic vents.

Methanopyrus kandleri: An Archaeal Methanogen Unrelated to all Other Known Methanogens
Systematic and Applied Microbiology, 1991Analysis of its 16S rRNA sequence shows that the newly discovered hyperthermophilic methanogen, Methanopryus kandleri, is phylogenetically unrelated to any other known methanogen. The organism represents a separate lineage originating near the root of the archaeal tree. Although the 16S rRNA sequence of Mp.

The Italian physicist Volta must be credited for observation that the bubbles arising at the surface of Lago Maggiore were inflammable (1776). Thirty years later, this combustible air was identified as methane (CH4), whose microbial origin was established only in 1868.

Beginning Genetics with Methanogens
1982There have been two meetings*, convened during the past year, specifically to determine how microbial genetics could be productively applied to obligately anaerobic microorganisms and to methanogenic species in particular. One of us (JNR) attended both of these meetings.

Proton Translocation in Methanogens
2011Methanogenic archaea of the genus Methanosarcina possess a unique type of metabolism because they use H(2)+CO(2), methylated C(1)-compounds, or acetate as energy and carbon source for growth. The process of methanogenesis is fundamental for the global carbon cycle and represents the terminal step in the anaerobic breakdown of organic matter in ...

Techniques for Cultivating Methanogens
2011Basic techniques for the cultivation of methanogenic archaea in anoxic media, where the O/R potential is maintained below (-) 330 mV under a pressurized atmosphere of 20% carbon dioxide, are described.

Methanogenic archaea metabolism
Science, 2017Structural Biology Most of the methane on Earth is produced by the metabolism of methanogenic archaea. The final step involves a reaction between methyl-coenzyme M and coenzyme B to give CoM-S-S-CoB and methane. Wagner et al. report a high-resolution structure of the methanogenic heterodisulfide reductase (HdtABC)-[NiFe]-hydrogenase, the enzyme that ...
