摘要
Acetate is an important CH4 precursor in nature, accounting for two-thirds of the CH4 produced in many natural habitats and in anaerobic bioreactors. Although microbial methanogenesis from acetate was first described in the early 1900s, the mechanism of methanogenesis from acetate was controversial until 1978, when it was demonstrated that a pure culture of Methanosarcina barkeri could grow on acetate (Mah et al., 1978; Smith and Mah, 1978; Weimer and Zeikus, 1978) and convert acetate to CH4 by a decarboxylation mechanism sometimes called the aceticlastic reaction. With the description of a similar mechanism for Methanothrix soehngenii in 1980 (Zehnder et al., 1980), it appeared that acetate decarboxylation was “the” mechanism for methanogenesis from acetate.

乙酸盐在自然界中是重要的CH 4前体,占许多自然栖息地和厌氧生物反应器中产生的CH 4的三分之二。虽然醋酸的微生物甲烷生成首先在20世纪初被描述,但是直到1978年才证明乙酸产甲烷的机制是有争议的,当时证明了纯天然的Methanosarcina barkeri培养物可以在醋酸盐上生长(Mah等,1978;史密斯和马,1978年; Weimer和Zeikus,1978)并通过脱羧机理将乙酸转化为CH 4,有时称为乙酸弹性反应。通过对1980年Methanothrix soehngenii的类似机制的描述(Zehnder等,1980),似乎乙酸脱羧是乙酸产甲烷的“机制”。
