Fermentation performance of the wild-type and PfdxE-hydA strains in serum bottles. A, B show the fermentation kinetics of the wild-type and PfdxE-hydA strains, respectively. C, D show the fermentation kinetics under conditions of extra acetate supplementation of the wild-type and PfdxE-hydA strains, respectively. The values represent the data for the average of two replicates and the error bars represent the standard errors of these experiments
