Thermodynamics and H2 Transfer in a Methanogenic, Syntrophic Community
Fig 4
Predicted individual and community by-product yields in the coculture system at a ratio of three M. hungatei to four S. fumaroxidans.
(A and D) Diagrams illustrating that yields are calculated around individual species (A) and the entire community (D). The plots show the yields of acetate, H2, CO2, and formate for S. fumaroxidans (per propionate) (B and C); CH4 for M. hungatei (per CO2) (B and C); and acetate, H2, CO2, formate, and CH4 for the entire reactor (per propionate) (E and F), as a function of the dilution rate of the reactor (X-axis). Plots are shown in which H2 and CO2 and exchanged (B and E), and in which formate and H2 is exchanged (C and F).
