Fig. 2: Electron flux analysis of C. acetobutylicum in phosphate-limited chemostat cultures.

Under acidogenic (pH 6.3) (a) and solventogenic (pH 4.4) (b) conditions. All values (mmol/gDCW/h) are normalized to the flux of glucose consumption. Data were extracted from ref. 19. The black arrow represents the total flux of Fdred oxidation, the red arrow the hydrogenase flux, the blue arrow the Ferredoxin-NAD+ flux, and the green arrow the ferredoxin-NADP+ flux.
