Fig. 3. Comparison of bioprocess parameters obtained during fed-batch cultivations on cheese whey with glucose, glycerol and lactose as co-substrates. Time-course profiles
of cell growth (A), DOT (B), lactose (C), lactobionic acid (D), co-substrates (E) and specific co-substrate consumption rates (F) are shown. The grey background in E indicates
the length (6 h) of the co-substrate feeding at a rate of 3.36 g/L h.
