Pseudomonas putida is used for fermentation of the lactose present in cheese whey. The bacteria are cultivated in a steady-state chemostat with sterile feed and at a dilution rate of D = 0.28 h-1. The lactose concentration in the feed and the effluent are S0 = 2.0 g/L and S = 0.10 g/L, respectively. The following information is available: YX/S = 0.45 g X/g S, YX/O2 = 0.25 g X/g O2, and C* = 8 mg/l (saturation DO). a. Determine the steady-state biomass concentration (X) and the specific rate of oxygen consumption (go2) b. What should be the oxygen transfer coefficient (Kia) to overcome oxygen transfer limitations if the desired DO concentration in the fermentation medium is 2 mg/l?
