ABSTRACT:
Pressure-driven conditions are used to activate and couple enzymes to ultrafiltration membranes such as a homoporous cellulosic membrane having pores of about 15-200 angstroms in diameter. The resultant enzyme-coupled ultrafiltration membranes can be used under pressure-driven conditions for enzymatic conversion of a substrate. The rate of conversion at low substrate concentrations is larger than the rate achieved with the native enzyme.
