Main data measured during the production phase using a xylose-based medium (40 g L−1). Data measured during the PBBR operation as a function of the dilution rate; a xylose (black down-pointing triangle), succinic (white up-pointing triangle), acetic (black circle), and formic (white square) acid concentration; b succinic acid productivity (black up-pointing triangle) and xylose conversion (white circle)
