Propionic acid production from glycerol under continuous mode of operation with cell recycling. Continuous propionic acid production from glycerol with cell recycling via a tangential flow filtration module with a ceramic membrane filter. The concentrations of biomass (▲), propionic acid (●), glycerol (◼), acetic acid (♦), succinic acid (✕), and n-propanol ( +) are presented during two different dilution rates. The first five stages correspond to D = 0.05 and the last three stages correspond to D = 0.025, with different medium composition (Gly:YE ratio of 22.60:10, 43.27:10, 51.40:10, 64.50:10, 64.50:20, 62.90:20, 62.90:10, 70:10 g/L, respectively)
