Fig. 3. Growth and metabolite concentrations in A. woodii wild type and hydBA mutant in bicarbonate-supplied medium supplemented with 20 mM fructose + hydrogen.
Displayed are the optical densities of the wild type (■) and the hydBA mutant (▲) as well as the hydrogen concentration in the headspace of the wild type (x) and the hydBA mutant (+) cultures (A). The fructose consumption of the wild type (◇)and hydBA mutant (▽) together with the concomitant production of acetate in the wild type (◆) and hydBA (▼) mutant was monitored over time (B). (n = 2)
