4. The growth of S. cerevisiae on glucose at anaerobic conditions in a batch bioreactor is given by C6H12O6+0.112NH30.59CH1.74N0.2O0.45+0.43C3H8O3+0.036H2O+1.3C2H5OH+1.54CO2 The growth occurs in a batch bioreactor with a volume of 104L. a. Draw and label the process flow diagram of the process. b. Determine the degrees of freedom of the problem. c. If the feed does not have any biomass the final biomass concentration produced is 60gL1. Determine the concentration of glucose and ammonium sulfate in the feed if all the glucose and ammonium sulfate are used up. d. Calculate also the concentration C3H8O3,C2H5OH and CO2 produced
