4. Chemostat cultivation of E.coli obeys Monod's equation: dX Hm SX dt ks +S Where Um = 0.7 h-l and ks = 5 g/L. The cell yield ( Yx/s ) is 0.65. You want to cultivate E.c in either ONE chemostat or TWO in series. The flow rate and the substrate concentratio the inlet stream should be 500 L/h and 85 g/L, respectively. The substrate concentration of outlet stream must be 5 g/L. a. If you use ONE chemostat, what should be size of the chemostat? What is the concentration of the outlet stream? b. If you use TWO chemostats in series, what sizes of the TWO chemostats will be m productive? What are the concentration of cells and substrate in the outlet stream the FIRST chemostat?

Transcribed Image Text:4. Chemostat cultivation of E.coli obeys Monod's equation:
Hm SX
ks +S
dX
dt
Where 4m =0.7 h' and ks = 5 g/L. The cell yield ( Yxs ) is 0.65. You want to cultivate E.coli
in either ONE chemostat or TWO in series. The flow rate and the substrate concentration of
the inlet stream should be 500 L/h and 85 g/L, respectively. The substrate concentration of the
outlet stream must be 5 g/L.
a. If you use ONE chemostat, what should be size of the chemostat? What is the cell
concentration of the outlet stream?
b. If you use TWO chemostats in series, what sizes of the TWO chemostats will be most
productive? What are the concentration of cells and substrate in the outlet stream of
the FIRST chemostat?
