Ruminant livestock are important sources of human food and global greenhouse gas emissions. Feed degradation and methane formation by ruminants rely on metabolic interactions between rumen microbes and affect ruminant productivity. Rumen and camelid foregut microbial community composition was determined in 742 samples from 32 animal species and 35(More)
In a previous study, we reported the ecological significance of uncultured bacterial group U2 in the rumen. In this study, the involvement of a recently cultured group U2 bacterium, strain R-25, in fiber digestion was tested in coculture with the fibrolytic bacterium Fibrobacter succinogenes S85. Dry matter (DM) digestion, growth and metabolites were(More)
Fibrobacter succinogenes is one of the most pivotal fibrolytic bacterial species in the rumen. In a previous study, we confirmed enhancement of fiber digestion in a co-culture of F. succinogenes S85 with non-fibrolytic ruminal strains R-25 and/or Selenomonas ruminantium S137. In the present study, mRNA expression level of selected functional genes in the(More)
