Suppose you have a microorganism that obeys the Monod's equation: C.C. max sx K + C. dC K+C, dt S. S. Where umax = 0.7 hr' and Ks = 5 g/t. The cell yield (Yx/s) is 0.65. You want to cultivate this microorganism in either one fermenter or two in series. The flow rate and the substrate concentration of the inlet stream should be 500 €/hr and 85 g/l, respectively. The substrate concentration of the outlet stream must be 5 g/e. a. If you use CSTR, what should be the size of fermenter? What is the cell concentration of the outlet stream? b. If you use two CSTRS in series, what sizes of the two fermenters will be most productive? What are the concentration of cells and substrate in the outlet stream of the first fermenter? c. What is the best combination of fermenter types and volumes if you use two fermenters in series? Suppose you have a microorganism that obeys the Monod's equation: C.C. max sx K + C. dC K+C, dt S. S.
