摘要

Presently, there are 120 species of methanogens, representing 33 genera. Rumen methanogens produce methane that contributes to both global enteric methane emissions and to a dietary energy loss to the host. Methanogens are strict anaerobes, are difficult to grow in vitro, require different substrates (hydrogen, carbon dioxide, acetate, methanol, methylamines, and formate) for methane production, and exist synergistically with bacteria and symbiotically with rumen ciliate protozoa. The differences in morphology and utilization of different substrates by different methanogens enable them to be found in a diverse number of habitats. With the introduction of new technologies, rumen methanogen research has greatly expanded. Future scientific advancements will contribute more insight into decreasing dietary energy losses and enteric methane emissions.

目前，产甲烷菌有120种，代表33属。瘤胃产甲烷菌会产生甲烷，导致全球肠道甲烷排放和膳食能量损失。产甲烷菌是严格的厌氧菌，难以在体外生长，需要不同的底物（氢气，二氧化碳，乙酸，甲醇，甲胺和甲酸盐）用于甲烷生产，并与细菌协同存在并与瘤胃纤毛虫原生动物共生。不同产甲烷菌在不同底物的形态和利用方面的差异使它们能够在多种生境中找到。随着新技术的引入，瘤胃甲烷生物的研究已经大大扩展。未来的科学进步将有助于减少饮食能量损失和肠道甲烷排放。
