Method for indirect quantification of CH4 production via H2O production using hydrogenotrophic methanogens

Frontiers in Microbiology, 2016
ydrogenotrophic methanogens are an intriguing group of microorganisms from the domain Archaea. They exhibit extraordinary ecological, biochemical, physiological characteristics colorbox{yellow}{and have a huge biotechnological potential}.

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.

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen. [PDF]

FEBS J
Serpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,

3D‐Printed Methane‐Producing Electrodes for Microbial Fuel Cells Developed Using Biogel Ink Containing Live Methanogens and White Charcoal

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,

Novel Methanobacterium Strain Induces Severe Corrosion by Retrieving Electrons from Fe⁰ under a Freshwater Environment

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.

Methanogens-Driven Arsenic Methylation Preceding Formation of Methylated Thioarsenates in Sulfide-Rich Hot Springs

, 2023
Hot springs represent a major source of arsenic release into the environment. Speciation is typically reported to be dominated by arsenite, arsenate, and inorganic thiolated arsenates.

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.
