SA production and sugar utilization by A. succinogenes in DAP-H and DDAP-H 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 in batch fermentations in mock sugars and DAP-H and DDAP-H. Productivity is calculated as succinate concentration divided by the fermentation time at each point. The numbers in c indicate the time point where the maximum cell density (OD₆₀₀) was reached and the specific OD₆₀₀ value for each culture
