Effect of Nickel Levels on Hydrogen Partial Pressure and Methane Production in Methanogens. [PDF]
PLoS ONE, 2016 Hydrogen (H2) consumption and methane (CH4) production in pure cultures of three different methanogens were investigated during cultivation with 0, 0.2 and 4.21 μM added nickel (Ni).

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1743-1761, July/August 2026.Abstract Tofu and tempeh, derived from soybeans, are widely consumed for their nutritional value and high protein content. However, the production of these foods generates nutrient‐rich wastewater that poses environmental challenges while offering opportunities for valorization.

mBio, 2019 The discovery of a methanogen that can conserve energy to support growth solely from the oxidation of organic carbon coupled to the reduction of an extracellular electron acceptor expands the possible environments in which methanogens might thrive.

Co-occurrence of Methanosarcina mazei and Geobacteraceae in an iron(III)-reducing enrichment culture
Frontiers in Microbiology, 2015 Methanosaeta harundinacea and Methanosarcina barkeri, known as classic acetoclastic methanogens, are capable of directly accepting electrons from Geobacter metallireducens for the reduction of carbon dioxide to methane, having been revealed as direct ...

Environmental Microbiology, Volume 28, Issue 7, July 2026.A novel polyP‐degrading enzyme with an activity differing from those currently known was found in Haloferax volcanii, conferring the ability for this microbe to grow on extracellular polyP. These findings further our understanding of the potential ecological roles of polyP and how archaea metabolise this essential biopolymer.

Formation of zero-valent iron in iron-reducing cultures of Methanosarcina barkeri.
Environmental Science and Technology, 2020 Methanogenic archaea have been shown to reduce iron from ferric [Fe(III)] to ferrous [Fe(II)] state, but minerals that form during iron reduction by different methanogens remain to be characterized.

Generation of a transmembrane gradient of Na+ in Methanosarcina barkeri [PDF]
European Journal of Biochemistry, 1987 A transmembrane Na+ gradient was generated by Methanosarcina barkeri during methanogenesis. The intracellular Na+ concentration amounted to approximately one fifth of the extracellular one. A secondary Na+/H+ antiport system was shown to be responsible for Na+ extrusion. This system could be inhibited by amiloride.

High-rate, High Temperature Acetotrophic Methanogenesis Governed by a Three Population Consortium in Anaerobic Bioreactors. [PDF]
PLoS ONE, 2016 A combination of acetate oxidation and acetoclastic methanogenesis has been previously identified to enable high-rate methanogenesis at high temperatures (55 to 65°C), but this capability had not been linked to any key organisms.

A Proteasome from the Methanogenic Archaeon Methanosarcina thermophila [PDF]
Journal of Biological Chemistry, 1995 A 645-kDa proteasome was purified from Methanosarcina thermophila which had chymotrypsin-like and peptidylglutamyl-peptide hydrolase activities and contained alpha (24-kDa) and beta (22-kDa) subunits. Processing of both subunits was suggested by comparison of N-terminal sequences with the sequences deduced from the alpha- and beta-encoding genes (psmA ...
