Methanogens are the only known microorganisms capable of methane production, making them of interest when investigating methane abatement strategies. A number of experiments have been conducted to study the methanogen population in the rumen of cattle and sheep, as well as the relationship that methanogens have with other microorganisms. The rumen methanogen species differ depending on diet and geographical location of the host, as does methanogenesis, which can be reduced by modifying dietary composition, or by supplementation of monensin, lipids, organic acids, or plant compounds within the diet. Other methane abatement strategies that have been investigated are defaunation and vaccines. These mitigation methods target the methanogen population of the rumen directly or indirectly, resulting in varying degrees of efficacy. This paper describes the methanogens identified in the rumens of cattle and sheep, as well as a number of methane mitigation strategies that have been effective in vivo.
产甲烷菌是唯一已知能够产生甲烷的微生物，因此在研究甲烷减排策略时，它们具有重要的研究意义。已经进行了许多实验来研究牛和羊瘤胃中的产甲烷菌种群，以及产甲烷菌与其他微生物的关系。根据宿主的饮食和地理位置，瘤胃产甲烷菌的种类也有所不同，而甲烷生成也会发生变化，可以通过改变饮食组成或通过在饮食中补充莫能菌素、脂质、有机酸或植物化合物来减少。已经研究了其他一些甲烷减排策略，如去原虫和疫苗。这些缓解方法直接或间接地针对瘤胃中的产甲烷菌种群，从而产生不同程度的效果。本文描述了在牛和羊的瘤胃中鉴定出的产甲烷菌，以及一些在体内有效的甲烷减排策略。
