Alginate Microbeads Production Method - Fluigent

The enzyme urease is immobilized in Ca-alginate beads, 2 mm in diameter. When the urea concentration in the bulk liquid is 0.5 mM, the observed rate of urea hydrolysis is 10 mM/h. The effective diffusivity of urea in Ca-alginate beads is 1.5 x 10^-5 cm^2/s, and the Michaelis-Menten constant for the enzymatic reaction is 0.2 mM. Assuming that the liquid film resistance on the beads may be neglected (i.e., [Ss] = [Sb]), determine the maximum rate of hydrolysis (Vmax), the Thiele modulus, and the e
