Thermodynamics and H2 Transfer in a Methanogenic, Syntrophic Community
Fig 1
Carbon and electron transport pathways in M. hungatei.
The methanogenesis pathway has an overall stoichiometry of CO2 + 4 H2 → CH4 + 2 H2O. Substrates and products are indicated with purple and blue ovals, respectively, while reactions with and without estimates are indicated with green and orange arrows, respectively. Metabolite and reaction abbreviations are given in S2 Dataset.
