Pseudomonas putida with is cultivated in a continuous culture under aerobic
conditions where The carbon and energy source in the feed is lactose with a
concentration of The effluent lactose concentration is desired to be If
the growth rate is limited by oxygen transfer, by using the following information:
a. Determine the steady-state biomass concentration (X) and the specific rate of oxygen
consumption

b. What should be the oxygen-transfer coefficient
in order to overcome oxygen-
transfer limitation
