Consider a 1000 mL chemostat (continuous reactor) operating with cellular recycling. The bioreactor is operated at steady state with glucose limitation with F = 100 mL/h and SF = 10 g/L. The values of YX/S = 0.5 gX/gS and the kinetic constants of the microorganism under the conditions employed are known (µmax = 0.2 h-1 and KS = 1.0 g/L). Knowing that the system operates with concentration factor B = 1.5 and recycling rate R = 0.7, calculate: a) the cell concentration in the recycle stream b) the cell concentration at the output of the system (bioreactor + separator)

Question
Consider a 1000 mL chemostat (continuous reactor) operating with cellular recycling. The bioreactor is operated at steady state with glucose limitation with F = 100 mL/h and SF = 10 g/L. The values of YX/S = 0.5 gX/gS and the kinetic constants of the microorganism under the conditions employed are known (µmax = 0.2 h-1 and KS = 1.0 g/L). Knowing that the system
operates with concentration factor B = 1.5 and recycling rate R = 0.7, calculate:
a) the cell concentration in the recycle stream
b) the cell concentration at the output of the system (bioreactor + separator)
