Influence of Liquid-to-Gas Ratio on the Syngas Fermentation Efficiency: An Experimental Approach

open access: yesBioengineering, 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

open access: yesFrontiers 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

Analysis of the Microbial Community in an Acidic Hollow-Fiber Membrane Biofilm Reactor (Hf-MBfR) Used for the Biological Conversion of Carbon Dioxide to Methane.

open access: yesPLoS 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 ...

Osmoregulation in methanogens [PDF]

open access: yes, 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.

Rumen methanogens and mitigation of methane emission by anti-methanogenic compounds and substances

open access: yesJournal of Animal Science and Biotechnology, 2017
Methanogenic archaea reside primarily in the rumen and the lower segments of the intestines of ruminants, where they utilize the reducing equivalents derived from rumen fermentation to reduce carbon dioxide, formic acid, or methylamines to methane (CH4).

Detection of Methanobrevobacter smithii and Methanobrevibacter oralis in Lower Respiratory Tract Microbiota

open access: yesMicroorganisms, 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.

Isoprene Production from Municipal Wastewater Biosolids by Engineered Archaeon Methanosarcina acetivorans

open access: yesApplied Sciences, 2021
Wastewater biosolids are a promising feedstock for production of value-added renewable chemicals. Methane-producing archaea (methanogens) are already used to produce renewable biogas via the anaerobic treatment of wastewater.

Production of Citrate by Anaerobic Fungi in the Presence of Co-culture Methanogens as Revealed by H NMR Spectrometry [PDF]

open access: yesAsian-Australasian Journal of Animal Sciences, 2013
The metabolomic profile of the anaerobic fungus Piromyces sp. F1, isolated from the rumen of goats, and how this is affected by the presence of naturally associated methanogens, was analyzed by nuclear magnetic resonance spectroscopy.

Sulfate-reducing bacteria and methanogens are involved in arsenic methylation and demethylation in paddy soils

open access: yesThe ISME Journal, 2019
Microbial arsenic (As) methylation and demethylation are important components of the As biogeochemical cycle. Arsenic methylation is enhanced under flooded conditions in paddy soils, producing mainly phytotoxic dimethylarsenate (DMAs) that can cause rice

Assessing the Ecophysiology of Methanogens in the Context of Recent Astrobiological and Planetological Studies

open access: yesLife, 2015
Among all known microbes capable of thriving under extreme and, therefore, potentially extraterrestrial environmental conditions, methanogens from the domain Archaea are intriguing organisms.
