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

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

Cross-reactivity of antibodies to different rumen methanogens demonstrated using immunomagnetic capture technology

Frontiers in Microbiology, 2022
Methane is produced in the rumen of ruminant livestock by methanogens, accounting for approximately 14.5% of anthropogenic greenhouse gas emissions in terms of global warming potential.

The repertoire of archaea cultivated from severe periodontitis.

PLoS ONE, 2015
In previous studies, the abundance and diversity of methanogenic archaea in the dental microbiota have been analysed by the detection of specific DNA sequences by PCR-based investigations and metagenomic studies.

Effects of Pig Manure and Its Organic Fertilizer Application on Archaea and Methane Emission in Paddy Fields

Land, 2022
Paddy fields account for 10% of global CH4 emissions, and the application of manure may increase CH4 emissions. In this study, high-throughput sequencing technology was used to investigate the effects of manure application on CH4 emissions and ...

Spatial Variations of the Methanogenic Communities in the Sediments of Tropical Mangroves. [PDF]

PLoS ONE, 2016
Methane production by methanogens in mangrove sediments is known to contribute significantly to global warming, but studies on the shift of methanogenic community in response to anthropogenic contaminations were still limited.

Metabolic versatility in methanogens

Current Opinion in Biotechnology, 2014
Methanogenesis is an anaerobic metabolism responsible for the generation of >90% of the methane formed on Earth today, with important implications for fuels production and global warming. Although methanogenic Archaea have been cultured for over 70 years, key insights regarding electron flow and energy conservation in methanogenesis have only recently ...

Resonance Raman analysis of intracellular vitamin B12 analogs in methanogenic archaea

Analytical Science Advances, 2022
Methanogenic archaea (methanogens) are microorganisms that can synthesize methane. They are found in diverse environments ranging from paddy fields to animal digestive tracts to deep‐sea hydrothermal vents.

Soil Inorganic Electron Acceptors and Carbon Substrates Hierarchically Govern Wetland Methanogenesis Temperature Response

Advanced Science, EarlyView.
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 ...

Human methanogen diversity and incidence in healthy and diseased colonic groups using mcrA gene analysis

BMC Microbiology, 2008
Background The incidence and diversity of human methanogens are insufficiently characterised in the gastrointestinal tract of both health and disease. A PCR and clone library methodology targeting the mcrA gene was adopted to facilitate the two-fold aim ...
