A chemostat with cell recycle is shown in the figure. The feed flow rate and culture volume are F = 75 L h−1 and V = 200 L, respectively. The glucose concentration in the feed CS0 = 15 g L−1. Assume Monod kinetics with specific cell growth rate μg = (1/CC) (dCC/dt) = μm CS / (KS + CS), where μm = 0.25 h−1 and KS = 1 g L−1. Assume maintenance and death rates to be zero, input feed to be sterile (CC0 = 0), and steady-state operation. The glucose concentration in the recycle stream, CS1, in g L−1, rounded off to 1 decimal place, is _________.
