Unformatted text preview: Assume that the Monod kinetics apply and the substrate utilization for maintenance and product synthesis is negligible. Data: max =2.0 hr-1 K s = 0.001 g /l Y x/s = 0.5 g cells/g substrate F= 1.0 l/hr V=1.0 l S in = 10 g/l (substrtate inlet conc.) 4) In a two stage chemostat system the volumes of the first and second reactors are V1=500 l and V2=300 l respectively. The first tank is used for biomass production and the second reactor is for secondary metabolite production. The flow rate, F=100 l/hr and the glucose concentration in the feed is Sin=5.0 g/l. The second tank is kept at a temperature above the maximum temperature for cell growth so that =0 in the second tank . Using the following constants determine the concentration of product in the effluent of the second tank. S in = 5.0 g/l Y x/s = 0.4 g cell/g substrate K s = 0.1 g/l max = 0.3 hr-1 Rp = 0.02 (g product/g cells hr) * X...
