2. (40 points) There is a batch microbial bioprocess for producing a polymer from sucrose where glucose is a byproduct. As a bioengineer, you were asked to improve the system by switching to fed-batch. You did several fermenter runs and obtained the following profiles for biomass, polymer concentration, sucrose and glucose concentrations. While the black closed symbols represent the batch run, the white open symbols represent the fed-batch run. For the fed-batch, you supplied the fermenter with sucrose at the time instants shown with the arrows. a. (20 points) Compare the two modes based on biomass, polymer concentration, sucrose and glucose concentrations. b. (20 points) Which mode between batch and fed-batch would you choose? Explain and justify your choice in detail based on biomass, polymer, sucrose and glucose yields
