Penicillin G splitting in a flow-through electro-membrane reactor with the membrane-bound enzyme

Original language description

Penicillin G (PenG) (0.05 mol dm(-3) in phosphate buffer, pH = 8) was hydrolyzed in a continuous flow-through electro-membrane reactor (EMR) with the penicillin G acylase (PGA) (EC 3.5.1.11) immobilized in 10% (w/v) polyacrylamide membrane with an area of 900 mm(2), thickness of 1 mm and enzyme activity of 100 U cm(-3) and 160 U cm(-3), respectively. The PenG was continuously fed to the substrate compartment adjacent to one membrane surface. Reaction products were washed from the membrane by a phosphatebuffer solution fed to the product compartment adjacent to the other membrane surface. The mean residence time of both streams was varied from 11.3 min to 45 min. An electric field perpendicular to the membrane surface was imposed on the reactor and theelectric current density was varied from 0 to 822 A m(-2). Substrate conversion was determined as a function of the mean residence time, of the applied electric current density and of the enzyme activity of the membrane. The conversion i
