Methanosarcina acetivorans: A Model for Mechanistic Understanding of Aceticlastic and Reverse Methanogenesis

open access: yesFrontiers in Microbiology, 2020
Acetate-utilizing methanogens are responsible for approximately two-thirds of the one billion metric tons of methane produced annually in Earth’s anaerobic environments.

The effect of pretreatment on VFA production from tofu and tempeh wastewater through anaerobic digestion batch

open access: yesBiofuels, 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.

Rumen methanogenic archaea and their correlation with enteric methane emission in ruminant animals: A systematic review and meta‐analysis

open access: yesJSFA reports, Volume 6, Issue 7, Page 265-279, July 2026.
Abstract Background Livestock, especially ruminants, are a major source of global methane emissions, primarily produced by methanogenic archaea during enteric fermentation. We performed a systematic review and meta‐analysis to account for factors that could influence the relationship between ruminal methanogenic populations and methane emissions, such ...

Microbial methanogenesis in the sulfate-reducing zone in sediments from Eckernförde Bay, SW Baltic Sea [PDF]

open access: yes, 2017
. The presence of surface methanogenesis, located within the sulfate-reducing zone (0–30 centimeters below seafloor, cmbsf), was investigated in sediments of the seasonally hypoxic Eckernförde Bay, southwestern Baltic Sea.

Structural Basis of Hydrogenotrophic Methanogenesis

open access: yesAnnual Review of Microbiology, 2020
Most methanogenic archaea use the rudimentary hydrogenotrophic pathway—from CO2and H2to methane—as the terminal step of microbial biomass degradation in anoxic habitats. The barely exergonic process that just conserves sufficient energy for a modest lifestyle involves chemically challenging reactions catalyzed by complex enzyme machineries with unique ...

Tracing methane sources in shallow waters of the North Sea: Biogenic signatures and hydrocarbon transport near abandoned wells

open access: yesLimnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Numerous abandoned wells in the North Sea may provide gas, particularly methane (CH4), migration pathways by penetrating shallow, biogenic gas accumulations. However, related sampling campaigns have been largely contradictory and lack a substantial database. Research cruise MSM98 targeted the abandoned wells B18‐1, DOK 1‐X, B11‐2, THOR and D‐1

Response of methane emissions, redox potential, and pH to eucalyptus biochar and rice straw addition in a paddy soil [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2016
This study aims to comprehend the links between soil Eh and pH changes in eucalyptus biochar (BC) and rice straw (RS) amended soils and CH4 emissions. Increased CH4 emission rates and high total CH4 emissions (TCH4 ) were found in RS soils.

Abundant interactions and feedbacks between aquatic deoxygenation and the other planetary boundaries suggest “unsafe” levels of oxygen loss with far‐reaching impacts

open access: yesLimnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Oxygen is critical for nearly all life on Earth, including aquatic species that breathe dissolved oxygen in both freshwater and marine systems. The rapid, global, and anthropogenic loss of dissolved oxygen known as “aquatic deoxygenation” threatens life in these environments, the human communities that depend on them, and Earth system ...

Impact of formation water geochemistry and crude oil biodegradation on microbial methanogenesis [PDF]

open access: yes, 2016
Converting non-producible crude oil to CH4 via methanogenic crude oil biodegradation in oil reservoirs could serve as one way to increase our energy profile.

Genetic resources for methane production from biomass described with gene ontology

open access: yesFrontiers in Microbiology, 2014
Methane (CH4) is a valuable fuel, constituting 70-95% of natural gas, and a potent greenhouse gas. Release of CH4 into the atmosphere contributes to climate change.
