2. A chemostat is run with a cell recycle system. The feed is 10g of glucose per liter and the feed flow rate is 100ml/h and the culture volume is 1000ml. It was measured that m=0.2h 1, and Ks=1.2g glucose/liter. The value of C is 2 and the recycle ratio is =0.6. The yield product /g cells and YP/S=0.1 and Po=0 a) Write the material balances for substrate and cells around the reactor and the around the cell separator. Assume steady state and sterile feed and Po=0 b) Calculate the productivities of product and biomass in this reactor. Neglect endogeneous metabolism
