Methanogen biomarkers in the discontinuous permafrost zone of stordalen, Sweden
, 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 ...

Diversity of gut methanogens in herbivorous animals
Animal, 2013 The digestion of plant biomass by symbiotic microbial communities in the gut of herbivore hosts also results in the production of methane, a greenhouse gas that is released into the environment where it contributes to climate change.

Advanced Science, EarlyView.This graphical abstract presents gut microbial cross‐feeding through a Mechanism–Technology–Application framework. It summarizes major resource‐transfer modes, the experimental and computational tools used to establish causality, and potential interventions involving dietary substrates, live biotherapeutic products, and engineered microbes.

Annals of Gastroenterological Surgery, EarlyView.ABSTRACT Small intestinal bacterial overgrowth (SIBO) has recently gained increasing attention as a potential cause of postoperative gastrointestinal symptoms following gastrointestinal cancer surgery. Surgical procedures can disrupt normal gastrointestinal physiology through anatomical reconstruction, impaired motility, reduced gastric acid secretion,

Characteristics of Methane Emissions and Practical Mitigation Strategies in Rice Paddy Fields [PDF]
대한환경공학회지Methane (CH4) is a potent greenhouse gas primarily emitted from flooded rice paddies under anaerobic soil conditions. As global food demand increases, CH4 emissions from rice cultivation are expected to rise, emphasizing the urgent need to establish ...

A Metagenome‐Assembled Genome Catalog From the Global Ruminant Microbiomes
Animal Research and One Health, EarlyView.The Ruminant Gastrointestinal MAG Catalog (RGMC) is a comprehensive global resource offering 40,812 strain‐level genomes across 53 bacterial and 4 archaeal classes. It greatly surpasses prior efforts in scale and diversity, serving as an essential foundation for research in ruminant nutrition, microbial function, and methane mitigation.

Levels of Water-Soluble Vitamins in Methanogenic and Non-Methanogenic Bacteria [PDF]
Applied and Environmental Microbiology, 1983 The levels of seven water-soluble vitamins in Methanobacterium thermoautotrophicum, Methanococcus voltae, Escherichia coli, Bacillus subtilis, Pseudomonas fluorescens , and Bacteroides thetaiotaomicron were compared by using a vitamin-requiring Leuconostoc strain. Both

Frontiers in Microbiology, 2018 Many anaerobic ciliated protozoa contain organelles of mitochondrial ancestry called hydrogenosomes. These organelles generate molecular hydrogen that is consumed by methanogenic Archaea, living in endosymbiosis within many of these ciliates.

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Mixed‐culture fermentation generally produces volatile fatty acids (VFAs) as a mixture of C2–C6 acids. Among operational parameters, temperature has a distinct effect on the microorganisms' metabolic activity, which can shift the composition of the metabolites.
