Abstract

Methanogenesis involves a novel set of coenzymes as one-carbon and electron carriers. Consequently, metabolic processes of methanogens deviate from those present in non-methanogenic bacteria. Methanogenic bacteria can be classified on the basis of substrate utilization. Group I (24 species) grows at the expense of hydrogen plus CO2 and/or formate and group II (7 species) uses methanol and/or acetate. Hydrogen-consuming methanogens are found as epi- or endosymbionts of anaerobic ciliates.

摘要

甲烷生成涉及一组作为一碳和电子载体的新型辅酶。因此，产甲烷菌的代谢过程不同于非产甲烷菌。产甲烷菌可根据底物利用情况进行分类。第一组（24种）以氢气加二氧化碳和/或甲酸为代价生长，第二组（7种）使用甲醇和/或乙酸盐。消耗氢气的产甲烷菌被发现是厌氧纤毛虫的外共生体或内共生体。
