You are using a two-stage chemostat system with volumes of 800 L for the first reactor and 350 L for the second reactor. The rationale is the first reactor is used for biomass production and the second is for product formation. The feed flow rate to the first reactor is set to 80 L/hr, and the glucose concentration in the feed is 4 g/L. You find the cell and glucose concentrations in the effluent of the first stage are 1.75 g/L and 0.3 g/L, respectively. Assume that growth is negligible in the second stage and the specific rate of product and formation is q_p = 0.2 g P/g cell h, and Y_p/s = 0.6 g P/g. Determine substrate concentrations in the effluent of the second reactor.
