Methanogens, Methane and Gastrointestinal Motility

open access: yesJournal of Neurogastroenterology and Motility, 2014
Anaerobic fermentation of the undigested polysaccharide fraction of carbohydrates produces hydrogen in the intestine which is the substrate for methane production by intestinal methanogens. Hydrogen and methane are excreted in the flatus and in breath giving the opportunity to indirectly measure their production using breath testing.

Methanogen population in a marine biofilm corrosive to mild steel [PDF]

open access: yes, 2003
This study was conducted to analyze the methanogen population in a corrosive marine biofilm based on 16S rDNA analysis, using a PCR-cloning-sequencing approach.

Environmental drivers of gaseous carbon fluxes in drained and rewetted Minnesota peatlands, U. S. A.

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Rewetting shows promise for mitigating carbon loss from drained peatlands. However, knowledge gaps remain in rewetting impacts on gaseous carbon fluxes and factors affecting rewetting success, especially in Minnesota and the Upper Midwest, United States, despite abundant degraded peatlands presenting restoration opportunities ...

The Rumen methanogen community and diurnal activity in pasture based dairy cows of the South Island [PDF]

open access: yes, 2012
The South Island of New Zealand offers a novel medium for studying methanogen community because dairy cows are fed almost exclusively on pasture and yet have unusually high milk production due to high dry matter intakes from high quality pastures.

Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

open access: yesJournal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1632-1642, August 2026.
Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...

Development of temporal temperature gradient electrophoresis for characterising methanogen diversity. [PDF]

open access: yes, 2005
Temporal temperature gradient electrophoretic (TTGE) analysis of 16S rDNA sequences was optimized to monitor the methanogen population present in water and sediments of a small eutrophic lake, Priest Pot, in the English Lake district.

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.

Relating Methanogen Community Structure to Function in Anaerobic Wastewater Digesters [PDF]

open access: yes, 2011
Anaerobic wastewater treatment is an environmentally and economically beneficial biotechnology in which the degradation of organic compounds in industrial and municipal wastewaters results in the production of methane, an alternative energy source.

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 ...
