Figure Lengend Snippet: Kinetics of growth, peptide concentrations and carbohydrate concentrations during continuous processes conducted in a classical (CBR, gray) or a membrane bioreactor (MBR, black) with the L. helveticus 45a strain. The first 24 h of culture were conducted in batch mode, then bioreactors were fed continuously at a dilution factor of 0.1 h –1 . (A) Strain growth was monitored by optical density determination at 600 nm. (B) Peptide concentration in bioreactor were determined by Folin-Ciocalteu reagent. (C) Lactose (circle) and lactic acid (triangle) concentrations were determined by high performance liquid chromatography (HPLC) using a Fast Fruit Juice column. Dotted lines represent the experimental data and full lines represent the mean from two independent experiments.
