Sequential batch fermentation of glucose for production of propionic acid. Glucose fermentation using A. acidipropionici DSM 4900 under sequential batch mode of operation with cell recycling. Fermentation temperature was maintained at 32 °C, pH at 6.5 by the addition of 5N NH4OH solution. A the concentrations of glucose (black square) and propionic acid (black diamond), B the concentration of succinic acid (black circle) and acetic acid (black triangle), C the concentration of biomass (+), and D the microbial growth shown as Ln(CDW) (–). The production medium contained ~ 40 g/L glucose, 0.5 mg/L biotin and 1× heat-treated potato juice
