Shifts in metabolic hydrogen sinks in the methanogenesis-inhibited ruminal fermentation: a meta-analysis

Frontiers in Microbiology, 2015
Maximizing the flow of metabolic hydrogen ([H]) in the rumen away from CH4 and towards volatile fatty acids (VFA) would increase the efficiency of ruminant production and decrease its environmental impact. The objectives of this meta-analysis were: i) To

Review: Biological consequences of the inhibition of rumen methanogenesis

Animal
Decreasing enteric CH4 emissions from ruminants is important for containing global warming to 1.5 °C and avoid the worst consequences of climate change.

H₂-Independent Growth of the Hydrogenotrophic Methanogen Methanococcus maripaludis

mBio, 2013
Hydrogenotrophic methanogenic Archaea require reduced ferredoxin as an anaplerotic source of electrons for methanogenesis. H2 oxidation by the hydrogenase Eha provides these electrons, consistent with an H2 requirement for growth.

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.

Magnetite drives microbial community restructuring and stimulates aceticlastic methanogenesis of type II Methanosarcina in mangrove sediments

Microbiome
Background Mangrove wetlands are critical hotspots of methane emissions, yet the role of naturally occurring minerals in shaping their microbial communities and methanogenic processes is poorly understood.

Maternal and infant gut microbiome

iMeta, EarlyView.
The maternal–infant continuum involves critical windows of host–microbiota co‐adaptation. Preconception, maternal and paternal microbiomes modulate immunity and reproduction. During pregnancy, a gut–placenta axis emerges, where microbial metabolites influence fetal growth or contribute to complications like gestational diabetes mellitus (GDM ...

Microbial DNA methylation links rumen transcriptional activity to methane emission divergence in dairy cows

iMeta, EarlyView.
Genome‐resolved methylomics uncovers the first DNA methylation atlas of the dairy cow rumen microbiome. Microbial DNA methylation profiles diverge between low‐ and high‐ methane‐emitting dairy cows despite limited taxonomic differences. Differential methylation is linked to transcriptional variation in genes involved in carbon metabolism, hydrogen ...
