Methanogen biomarkers in the discontinuous permafrost zone of stordalen, Sweden [PDF]
, 2014 Permafrost peatlands are both an important source of atmospheric CH4 and a substantial sink for atmospheric CO2. Climate change can affect this balance, with higher temperatures resulting in the conversion of permafrost soils to wetlands and associated ...

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 ...

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 ...

Progress in the development of vaccines against rumen methanogens
Animal, 2013 Vaccination against rumen methanogens offers a practical approach to reduce methane emissions in livestock, particularly ruminants grazing on pasture. Although successful vaccination strategies have been reported for reducing the activity of the rumen ...

METHANOGEN METABOLIC FLEXIBILITY [PDF]
, 2022 Methanogens are obligately anaerobic archaea which produce methane as a byproduct of their respiration. They are found across a wide diversity of environments and play an important role in cycling carbon in anaerobic spaces and the removal of harmful ...

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 ...

Isolation of a Novel Thermophilic Methanogen and the Evolutionary History of the Class Methanobacteria [PDF]
, 2022 Methanogens can produce methane in anaerobic environments via the methanogenesis pathway, and are regarded as one of the most ancient life forms on Earth.
