Growth yield map for a fermentative species uptaking extracellular electrons during a fermentation. (a) Glycerol fermentation by C. pasteurianum. (b) Glucose fermentation by C. pasteurianum. (c) Glucose fermentation by P. freudenreichii. Dashed lines represent contour line for the specific value obtained when α = 0 (fermentative growth yield). Solid lines represent contour lines of growth yields. These lines are green or red when higher or lower than the fermentative growth yield, respectively. Interactions are described as “Energetic” regarding energy partitioning during IET and as “Global” when biomass production of each IET partner is considered. α: fraction of substrate used for dissipating electrons from IET (normalized on substrate consumption for catabolism); ERAP: Potential of the redox active protein involved in the electron dissipation reaction; SHE: Standard Hydrogen Electrode.
