Soil Inorganic Electron Acceptors and Carbon Substrates Hierarchically Govern Wetland Methanogenesis Temperature Response. [PDF]
Adv Sci (Weinh)ABSTRACT Wetlands constitute Earth's largest natural methane (CH4) source, yet projections of their climate feedback remain uncertain due to poorly constrained temperature sensitivity (Q10‐CH4) of microbial methanogenesis. While water table dynamics have been demonstrated to regulate wetland methanogenesis by altering key soil conditions such as ...

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.

Recent advances in constructed wetlands methane reduction: Mechanisms and methods
Frontiers in Microbiology, 2023 Constructed wetlands (CWs) are artificial systems that use natural processes to treat wastewater containing organic pollutants. This approach has been widely applied in both developing and developed countries worldwide, providing a cost-effective method ...

Mechanism of Electromethanogenic Reduction of CO2 by a Thermophilic Methanogen [PDF]
, 2013 To establish a biotechnological system to convert CO2 into methane, we are trying to develop a new CO2 bio-conversion technology based on “electromethanogenesis”, a new bio-electrolysis reaction using microbially-catalyzed electrode.

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

Technical note: Comparison of biomarker and molecular biological methods for estimating methanogen abundance [PDF]
, 2014 Quantitative real-time PCR (qPCR) has become a popular method for estimation of methanogen abundance in the ruminant digestive tract. However, there is no established method in terms of primer choice and quantification, which means that results are ...

Genomic Variation Influences Methanothermococcus Fitness in Marine Hydrothermal Systems
Frontiers in Microbiology, 2021 Hydrogenotrophic methanogens are ubiquitous chemoautotrophic archaea inhabiting globally distributed deep-sea hydrothermal vent ecosystems and associated subseafloor niches within the rocky subseafloor, yet little is known about how they adapt and ...
