Kinetics of the sequential batch propionic acid fermentation using 30 g/L glucose, 60 g/L crude glycerol, 1.25× HTPJ ± biotin using A. acidipropionici DSM 4900 cells for 10 sequential batches with cell recycle. The parameters shown are: A changes in biomass concentration from batch to batch, B changes in Ln(CDW) from batch to batch, C changes in volumetric PA production rates from batch to batch, D changes in propionic acid volumetric productivity as a function of initial biomass concentration, E Changes in Ln(QP) as a function of initial biomass concentration, and F correlation between volumetric substrate consumption rate and volumetric PA production rate
