TLDR
The changes in the frequency of association can be correlated with the relative attribution to the H2 production by hydrogenogenic bacteria and rumen ciliates.Abstract:
1. The frequency of association between methanogenic bacteria and ovine rumen ciliates was studied in the rumen fluid of a fistulated sheep. 2. A period of fasting and flushing of the rumen content with nitrogen resulted in a relatively high association, whereas the intake of food and flushing with hydrogen caused a detachment of the methanogenic bacteria from the ciliates. 3. The changes in the frequency of association can be correlated with the relative attribution to the H2 production by hydrogenogenic bacteria and rumen ciliates.read more

Methane emissions from cattle.
TL;DR: Knowing the factors that impact methane production can result in the development of mitigation strategies to reduce methane losses by cattle and implementation of these strategies should result in enhanced animal productivity and decreased contributions by cattle to the atmospheric methane budget.

Energetics of syntrophic cooperation in methanogenic degradation.
TL;DR: S syntrophically fermenting bacteria synthesize ATP by substrate-level phosphorylation and reinvest part of the ATP-bound energy into reversed electron transport processes, to release the electrons at a redox level accessible by the partner bacteria and to balance their energy budget.

Methane production by ruminants: its contribution to global warming
TL;DR: The most promising areas for future research for reducing methanogenesis are the development of new products/delivery systems for anti-methanogenic compounds or alternative electron acceptors in theRumen and reduction in protozoal numbers in the rumen.

The Rumen Protozoa
TL;DR: In addition to the bacteria in the rumen there are many larger organisms which at various times have been designated protozoa, of which there are two groups both in the subclass Trichostomatia and the entodiniomorphs.
Journal Article
Rumen microbial ecosystem
TL;DR: The necessity to use molecular biology techniques for identification and characterization of rumen microbes has been emphasized in this review and the microbial ecosystem is well studied for the rumen of domesticated animals, but it is poorly studied in buffalo and wild ruminants.

TL;DR: In 11 species of rumen ciliates belonging to nine genera of the family Ophryoscolecidae an ectosymbiosis with methanogenic bacteria was found, which may reflect a metabolic interaction in which efficient interspecies hydrogen transfer benefits both partners.

TL;DR: It is concluded that nonmethanogenic microbes metabolize intercellular formate in the rumen, and CO(2) and H( 2) are the principal substrates for rumen methanogenesis.
Journal ArticleDOI
Hydrogen as an intermediate in the rumen fermentation.
TL;DR: It is concluded that hydrogen is a very important intermediate in the rumen production of methane because it correlated more closely with concentration of dissolved hydrogen than with formate.
