Pseudomonas putida with µm = 0.5 h^-1 is cultivated in a continuous culture under aerobic conditions where D = 0.28 h^-1 . The carbon and energy source in the feed is lactose with aconcentration of S₀ = 2 g/l. The effluent lactose concentration is desired to be S = 0.1 g/l. If the growth rate is limited by oxygen transfer, by using the following information:

What should be the oxygen-transfer coefficient (k_La) in order to overcome oxygentransfer limitation (i.e., CL = 2 mg/l)? ___________________
