Question
The daily production of a growth-associated byproduct (P) is 250 kg/day. The continuous bioreactor without recycle is fed with a substrate solution (S) with a concentration of 60 g/L at a flow rate of 500 L/h. In steady state condition, calculate:
a) the product concentration (Cp).
b) the conversion of the limiting substrate.
c) the cell concentration (Cx).
d) the volume of the bioreactor.
Data μmax = 0.20 h-1, KS = 0.70 g.L-1, YX/S =0.50 gX/gS, YP/S = 0.35 gP/gS
(answers: Considering P0 = 0 and X0 = 0: a) P = 20.83 g/L; b) 99.2% conversion; c) X = 29.76 g/L; d) V = 6071 L)
