MOESM1 of Continuous succinic acid fermentation by Actinobacillus succinogenes in a packed-bed biofilm reactor

Additional file 1: Figure S1. Biofilm of A. succinogenes. a) at the end of the start-up phase; b) after 5 months of continuous operation. Figure S2. Time-course profiles of the fermentation results during the production phase from glucose. a Glucose (▼) and cell concentration (○) and dilution rate (dashed line); b succinic (∆), acetic (●) and formic (□) acid concentration and dilution rate. Figure S3. Time-course profiles of the fermentation results during the adaptation phase from glucose to xylose. a Glucose (▼), xylose (■) and cell concentration (○); b succinic (∆), acetic (●), and formic (□) acid concentration and xylose percentage (dashed line) in the medium. The dilution rate was set to 1.24 h−1. Figure S4. Time-course profiles of the fermentation results during the production phase from xylose. a Xylose (▼) and cell concentration (○) and dilution rate (dashed line); b succinic (∆), acetic (●), and formic (□) acid concentration and dilution rate. Figure S5. Time-course profiles of the fermentation results during the production phase from GAX medium. a Sugars [glucose (▼), xylose (■), and arabinose (∇)] and cell concentration (○) and dilution rate (dashed line); b succinic (∆), acetic (●), and formic (□) acid concentration and dilution rate.
