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 ...

Review: Methanogens and methane production in the digestive systems of nonruminant farm animals
Animal, 2021 The greenhouse gases (GHGs) derived from agriculture include carbon dioxide, nitrous oxide, and methane (CH4). Of these GHGs, CH4, in particular, constitutes a major component of the GHG emitted by the agricultural sector.

Osmoregulation in methanogens [PDF]
, 1993 Our major goal of our work has been to develop and use NMR techniques to study how methanogenic archaebacteria deal with osmotic stress with the hope of providing insights into increasing the salt tolerance of other cells.

Fecal Methanogens and Vertebrate Evolution [PDF]
Evolution, 1996 It has been assumed that the feeding habits of vertebrates predispose the variety of intestinal differentiations and the composition of the microbial biota living in their intestinal tracts. Consequently, the presence of methanogenic bacteria in the various differentiations of the large intestine and the foregut of herbivorous vertebrates had been ...

Microorganisms, 2020 Methanogens, the sole microbes producing methane, are archaea commonly found in human anaerobic microbiota. Methanogens are emerging as opportunistic pathogens associated with dysbiosis and are also detected and cultured in anaerobic abscesses.

Effect of ammonium and acetate on methanogenic pathway and methanogenic community composition [PDF]
FEMS Microbiology Ecology, 2012 Methanogenesis from acetate (aceticlastic methanogenesis or syntrophic acetate oxidation (SAO) coupled with hydrogenotrophic methanogenesis) is the most important step for the biogas process. The major environmental factors influencing methanogenesis are volatile fatty acids, ammonia, pH, and temperature. In our study, the effect of acetate and ammonia

Evidence for a plasmid in a methanogenic bacterium [PDF]
Journal of Bacteriology, 1983 Among 15 strains of methanogens, one plasmid, pMP1, was identified in the new coccoid isolate PL-12/M. It could not be detected in the cleared lysate, but it was detected in the viscous pellet. The plasmid had a molecular weight of ca. 4.6 x 10(6). A restriction enzyme cleavage map of the cloned plasmid was derived.
