Oscillatory behavior of intracellular redox in C. autoethanogenum continuous cultures. (A) Oscillations in intracellular redox ratios and biomass concentration for two biological replicate cultures (#1 and #2). (B) Oscillations in Nfn driving force and biomass concentration for two biological replicate cultures (#1 and #2). Heat maps show the relative change of the respective parameter between its minimum and maximum value (denoted on the right of heat map) with color scale shown on the top. Heat maps were generated with values derived from using spline (third order polynomial cubic spline with point count 1) on the measured values to achieve higher resolution. time, fermentation duration from culture inoculation; Nfn driving force, NADH/NAD⁺×NADP⁺/NADPH.
