Lower methane emissions were associated with higher abundance of ruminal Prevotella in a cohort of Colombian buffalos.

We propose that higher abundance of ruminal Prevotella increases the production of propionic acid and, in doing so, reduces the amount of hydrogen available for methanogenesis. However, further experimentation is required to ascertain the role of Prevotella on methane production and its potential to act as a methane production mitigator.
