1. Conversion of glucose to fructose, used as sweetener in the food industry, is catalyzed by glucose isomerase produced by Bacillus coagulans. It is desired to culture this bacteria in a chemostat of volume 1 L. Data for the process is shown below. Concentration (g/L) Flow rate Glucose Bacillus (mL/hr) Fructose Concentration Concentration Concentration 30 12 14 1.1 26 9 17 1.3 23 7 19 1.5 20 3 20 1.7 a. What flowrate should be maintained in the chemostat to prevent wash out of cells? Assume a sterile feed and an inlet substrate concentration of 40 g/L. b. What would be the cell and substrate concentration if the flowrate is set to (a)
