In silico and in vitro studies revealed that rosmarinic acid inhibited methanogenesis via regulating composition and function of rumen microbiota

open access: yesJournal of Dairy Science
: Inhibition of methyl-coenzyme M reductase can suppress the activity of ruminal methanogens, thereby reducing enteric methane emissions of ruminants. However, developing specific and environmentally friendly inhibitors is a challenging endeavor.
