Question

A chemostat with cell recycle is shown in the figure. The feed flow rate and culture volume are $F = 75$ L/h and $V = 200$ L, respectively. The glucose concentration in the feed $C_{S0} = 15$ g/L. Assume Monod kinetics with specific cell growth rate \mu_g=$$ \frac{1}{C_c} \frac{dC_c}{dt} = \frac{\mu_m C_S}{K_s + C_S} ,, where $\mu_m = 0.25$ h$^{-1}$ and $K_s = 1$ g/L. Assume maintenance, and death rates to be zero, input feed to be sterile ($C_{S0} = 0$), and steady-state operation. The glucose concentration in the recycle stream, $C_{S1}$, in g/L, rounded off to 1 decimal place, is ____.
