The complete genome sequence of the rumen methanogen Methanobrevibacter millerae SM9

Methanobrevibacter millerae SM9 was isolated from the rumen of a sheep maintained on a fresh forage diet, and its genome has been sequenced to provide information on the phylogenetic diversity of rumen methanogens with a view to developing technologies for methane mitigation. It is the first rumen isolate from the Methanobrevibacter gottschalkii clade to have its genome sequence...

The complete genome sequence of Eubacterium limosum SA11, a metabolically versatile rumen acetogen

Acetogens are a specialized group of anaerobic bacteria able to produce acetate from CO2 and H2 via the Wood–Ljungdahl pathway. In some gut environments acetogens can compete with methanogens for H2, and as a result rumen acetogens are of interest in the development of microbial approaches for methane mitigation. The acetogen Eubacterium limosum SA11 was isolated from the rumen...

The Glycobiome of the Rumen Bacterium Butyrivibrio proteoclasticus B316T Highlights Adaptation to a Polysaccharide-Rich Environment

Determining the role of rumen microbes and their enzymes in plant polysaccharide breakdown is fundamental to understanding digestion and maximising productivity in ruminant animals. Butyrivibrio proteoclasticus B316T is a Gram-positive, butyrate-forming rumen bacterium with a key role in plant polysaccharide degradation. The 4.4Mb genome consists of 4 replicons; a chromosome, a...

The Genome Sequence of the Rumen Methanogen Methanobrevibacter ruminantium Reveals New Possibilities for Controlling Ruminant Methane Emissions

Background Methane (CH4) is a potent greenhouse gas (GHG), having a global warming potential 21 times that of carbon dioxide (CO2). Methane emissions from agriculture represent around 40% of the emissions produced by human-related activities, the single largest source being enteric fermentation, mainly in ruminant livestock. Technologies to reduce these emissions are lacking...
