Fed batch fermentation is used to produce a certain bio product. The initial volume is 100L with a flow rate of 10L/hr, the substrate concentration in the feed is 100g substrate/L and the cell concentration in the reactor is 10g cells /L. Monod parameters are: m=0.2hr1,Ks=0.5g/L and Yx/s=0.3g cell/g substrate. Calculate: a. The culture volume after 5 hours. b. Substrate concentration after 5 hours. c. Concentration and total amount of cells after 5 hours. d. Concentration and total amount of product, (qp=0.02g product /g cell, P0=0.05g product /L)
