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 ...

Frontiers in Microbiology, 2023 Wetlands are an important source of atmospheric methane (CH4) and are sensitive to global climate change. Alpine swamp meadows, accounting for ~50% of the natural wetlands on the Qinghai-Tibet Plateau, were considered one of the most important ecosystems.

Technical note: Comparison of biomarker and molecular biological methods for estimating methanogen abundance [PDF]
, 2013 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 ...

BMC Microbiology, 2018 Background This study was conducted to examine effects of nitrate on ruminal methane production, methanogen abundance, and composition. Six rumen-fistulated Limousin×Jinnan steers were fed diets supplemented with either 0% (0NR), 1% (1NR), or 2% (2NR ...

Relating Anaerobic Digestion Microbial Community and Process Function [PDF]
, 2016 Anaerobic digestion (AD) involves a consortium of microorganisms that convert substrates into biogas containing methane for renewable energy. The technology has suffered from the perception of being periodically unstable due to limited understanding of ...

Evolving understanding of rumen methanogen ecophysiology
Frontiers 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

Insights into the Ecological Roles and Evolution of Methyl-Coenzyme M Reductase-Containing Hot Spring Archaea [PDF]
, 2019 Several recent studies have shown the presence of genes for the key enzyme associated with archaeal methane/alkane metabolism, methyl-coenzyme M reductase (Mcr), in metagenome-assembled genomes (MAGs) divergent to existing archaeal lineages.
