Zymomonas mobilis cells are used for chemostat culture to produce ethanol in a 60 m3 fermenter. The yield of biomass from substrate is 0.06 g/g and YP/X is 7.7 g/g. The maximum specific growth rate of Z. mobilis is approximately 0.3 h-1 . The feed contains 12 g/L glucose, and KS for the organism is 0.2 g/L. Assume the culture follows Monod kinetics. Ignore maintenance energy. a. Draw a schematic for the problem. Label all appropriate streams, and list any assumptions.
