Acetate formation from pyruvate in the absence of methanogenesis

Acetate formation from pyruvate in the absence of methanogenesis 

An electrogenic Na /H antiporter turns out to have an important function in the energetics of methanogens. This cation exchanger has been shown to be stoichiometrically involved in the interconversion of primary potentials of Na and in the various methanogenic pathways. During methane formation from H2/CO2 and probably also
