SA production and sugar consumption by A. succinogenes in mock media in batch fermentations. Profiles of xylose (a) glucose (d) arabinose (e) and galactose (f) consumption, succinate production (b) and succinate productivity (c) by A. succinogenes of different mock hydrolysates. Productivity is calculated as succinate concentration divided by the fermentation time at each point. Sugars and inhibitors in the different media are (1) mock DAP-H = sugars (80 g/L) + furfural (1.7 g/L) + HMF (0.17 g/L) + AA (5.8 g/L), (2) mock DDAP-H = sugars (80 g/L) + furfural (1.7 g/L) + HMF (0.17 g/L) + AA (2.3 g/L), (3) mock sugars + AA = sugars (80 g/L) + AA (5.8 g/L), and (4) mock sugars = only sugars (80 g/L). Insets in the graphs b, d, e, and f present the profiles corresponding to the first few hours of fermentation. The numbers in c indicate the time point where the maximum cell density (OD600) was reached and the specific OD600 value for each culture
