Bioenergetics of methanogenesis from acetate by Methanosarcina barkeri [PDF]

open access: yesJournal of Bacteriology, 1988
Methane formation from acetate by resting cells of Methanosarcina barkeri was accompanied by an increase in the intracellular ATP content from 0.9 to 4.0 nmol/mg of protein. Correspondingly, the proton motive force increased to a steady-state level of -120 mV.

A biochemical framework for anaerobic oxidation of methane driven by Fe(III)-dependent respiration

open access: yesNature Communications, 2018
The unavailability of pure cultures has prevented a mechanistic understanding of anaerobic methanotrophy. Here the authors report a biochemical investigation of Methanosarcina acetivorans that supports a pathway anchored by Fe(III)-dependent mechanisms ...

Analyzing conformational changes in single FRET-labeled A1 parts of archaeal A1AO-ATP synthase

open access: yes, 2018
ATP synthases utilize a proton motive force to synthesize ATP. In reverse, these membrane-embedded enzymes can also hydrolyze ATP to pump protons over the membrane.

ADP-dependent Phosphofructokinases in Mesophilic and Thermophilic Methanogenic Archaea [PDF]

open access: yes, 2001
Phosphofructokinase (PFK) is a key enzyme of the glycolytic pathway in all domains of life. Two related PFKs, ATP-dependent and PPi-dependent PFK, have been distinguished in bacteria and eucarya, as well as in some archaea.

Ratoon Season Rice Reduces Methane Emissions by Limiting Acetic Acid Transport to the Rhizosphere and Inhibiting Methanogens

open access: yesAdvanced Science, Volume 13, Issue 8, 9 February 2026.
This study finds that the interaction between ABA‐OsCIPK2‐OsSWEET1A reduces the allocation of methane producing bacteria carbon source (acetic acid) content to the rhizosphere soil of ratoon season rice, thereby reducing methane emissions. Abstract Rice paddies are a major, persistent source of atmospheric methane (CH4), emission rates depend on the ...

NanoFe3O4 as Solid Electron Shuttles to Accelerate Acetotrophic Methanogenesis by Methanosarcina barkeri

open access: yesFrontiers in Microbiology, 2019
Magnetite nanoparticles (nanoFe3O4) have been reported to facilitate direct interspecies electron transfer (DIET) between syntrophic bacteria and methanogens thereby improving syntrophic methanogenesis.

Structure and Spatial Heterogeneity of Chemosynthesis‐Based Deep‐Sea Archaeal and Bacterial Communities in Western South Atlantic

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We report an extensive investigation of prokaryotic communities from a methane cold‐seep area in the Western South Atlantic Ocean (Southern Brazil) employing a broad sample set, including three distinct geographic areas (A, C and E) across a depth gradient (up to 18 m below the seafloor) related to the sulfate–methane transition zone (SMTZ).

Expanding the Diet for DIET: Electron Donors Supporting Direct Interspecies Electron Transfer (DIET) in Defined Co-Cultures

open access: yesFrontiers in Microbiology, 2016
Direct interspecies electron transfer (DIET) has been recognized as an alternative to interspecies H2 transfer as a mechanism for syntrophic growth, but previous studies on DIET with defined co-cultures have only documented DIET with ethanol as the ...
