Over the last two decades, a number of approaches have been adopted to mitigate CH 4 emissions. However, the mechanisms of methanogenesis have still not been fully defined. According to the genome sequences of M. ruminantium in the rumen and of M. AbM4 in the abomasum, the pathways of carbon dioxide (CO 2) reduction and for…
