Methanogenic archaea in peatlands [PDF]
FEMS Microbiology Letters, 2020 ABSTRACT Methane emission feedbacks in wetlands are predicted to influence global climate under climate change and other anthropogenic stressors. Herein, we review the taxonomy and physiological ecology of the microorganisms responsible for methane production in peatlands.

Diversity of Methanogens in Animals’ Gut
Microorganisms, 2020 Methanogens are members of anaerobe microbiota of the digestive tract of mammals, including humans. However, the sources, modes of acquisition, and dynamics of digestive tract methanogens remain poorly investigated.

Macromolecular Materials and Engineering, 2023 Methanogens are used as catalysts for cathodes in microbial fuel cells, to reduce CO2 to CH4. However, the attachment of microbes to the electrodes via culturing is time‐consuming, and inadequate biofilm formation can lead to lesser surface area coverage,

Microorganisms, 2022 Methanogens capable of accepting electrons from Fe0 cause severe corrosion in anoxic conditions. In previous studies, all iron-corrosive methanogenic isolates were obtained from marine environments.

An Unexpectedly Broad Thermal and Salinity-Tolerant Estuarine Methanogen Community
Microorganisms, 2020 Moderately thermophilic (Tmax, ~55 °C) methanogens are identified after extended enrichments from temperate, tropical and low-temperature environments.

Influence of Liquid-to-Gas Ratio on the Syngas Fermentation Efficiency: An Experimental Approach
Bioengineering, 2020 Syngas fermentation by methanogens is a novel process to purify biogas. Methanogens are able to ferment non-desirable CO2, H2, and CO to methane. However, to use methanogens on an industrial scale, more research has to be done.

Evolving understanding of rumen methanogen ecophysiology
Frontiers in Microbiology, 2023 Production of methane by methanogenic archaea, or methanogens, in the rumen of ruminants is a thermodynamic necessity for microbial conversion of feed to volatile fatty acids, which are essential nutrients for the animals. On the other hand, methane is a

Rumen methanogens: a review [PDF]
Indian Journal of Microbiology, 2010 The Methanogens are a diverse group of organisms found in anaerobic environments such as anaerobic sludge digester, wet wood of trees, sewage, rumen, black mud, black sea sediments, etc which utilize carbon dioxide and hydrogen and produce methane. They are nutritionally fastidious anaerobes with the redox potential below -300 mV and usually grow at pH

PLoS ONE, 2015 Hydrogenotrophic methanogens can use gaseous substrates, such as H2 and CO2, in CH4 production. H2 gas is used to reduce CO2. We have successfully operated a hollow-fiber membrane biofilm reactor (Hf-MBfR) for stable and continuous CH4 production from ...
