  Ruminal fermentation has been well studied and includes cellulolytic microorganisms to hydrolyze cellulose tomonomers, acidogenic microbes including cellulolytic microorganism to convert the monomers to volatile fatty acids(VFA), hydrogen and carbon dioxide and methanogens to convert the acetic acid, hydrogen and carbon dioxide tomethane. Notably, methane production in ruminants causes energy loss for the animal and emitted methanecontributes significantly to greenhouse gases in the atmosphere. The present study focuses on selectively inhibitingof the methanogens using 2–bromoethanesulfonate (BES) and its effect on ruminal fermentation in an anaerobicrumen bioreactor model system. It was found that BES inhibited methane production (99.7%) and that addition ofBES decreased the total VFA productivity from 3 g/L/day to 1.3 g/L/day. Our study also found that addition of BESnot only .. View More»
