(5 pts) A strain of yeast is being cultivated in a 30-L CSTF with a cell recycling system 9cell
settler) as shown in the flowing figure. The cell settler was designed so that the cell
concentration of its outlet stream is 30% of that of its inlet stream, whereas the substrat
concentrations of the two streams are the same. The growth rate of the cells can be represented
by the Monod kinetics with the parameters max=0.3hr-1,KS=0.05gL, and Yxs=
0.025gg. The inlet substrate concentration is 100gL and the flow rate is 20Lhr. The feed
stream is sterile. Calculate the steady-state substrate and cell concentrations in the fermenter.
