Ethanol will be produced in a fed-batch production system using Saccharomyces cerevisiae. Initial production volume is V0= 40 m3, and 150 kg/m3 glucose is fed to the system at a flow rate of 2 m3/hour from the 0th moment. Since the maximum specific growth rate of S. cerevisiae was m=0.6 h-1, Ks= 0.4 kg/m3, after 25 hours of constant feeding; a) The final volume in the reactor (V), b) Calculate the steady state glucose concentration (S).
