Dynamics in redox cofactor ratios. Dynamics in the NADPH/NADP (A) and NADH/NAD (B) ratios during anaerobic batch fermentation of 20 g/L glucose and 40 g/L xylose using strains TMB3057 (XR/XDH, white markers) and TMB3359 (XI, black markers). Dotted lines in B) represent the 95% confidence interval of the value in TMB3057 at time point 38.5 h. Errors are given as 95% confidence intervals of the means calculated from duplicate experiments for each strain (4 ≤ n ≤ 10). The shaded area indicates the period until glucose depletion.
