Bioengineering 161AFall 2018Homework #3Due Oct 16th before the end of class to the TAs1. You have immobilized lactase onto solid porous spheres to produce lactose-free milk in a CSTR. The bulk concentration of lactose is maintained throughout the reactor (except within the boundary layer of each particle) at 25 mM. The reactor is operated in such a manner that kL = 0.4 cm/s, and this lactase enzyme as the following kinetic properties: V’max = 50 µmol/(cm2 Km = 10 mM a. What is the approximate steady-state flux for the reactor? b. Calculate the Damkohler number for this condition? Is the process reaction limited or diffusion limited?
