Two continuous stirred-tank fermenters are connected in series, the first having an operational volume of 100 L and that of the second being 50 L. The feed to the first fermenter is sterile and contains 5000 mg/L of substrate, being delivered to the fermenter at 18 L/h. If the microbial growth can be described by the Monod kinetic model with µm= 0.25 h-1 and Ks = 120 mg/l. What would happen if the flow were from the 50 L fermenter to the 100 L fermenter?
