摘要：

In this paper the kinetic behavior of a cross-flow bioreactor equipped with capillary ultrafiltration bioactive membranes is discussed with reference to hydrolysis of lactose to glucose and galactose, catalyzed by a cytoplamsic beta -galactosidase. An experimental investigation is presented of the effects of transmembrane pressure and substrate feed concentration on reactor performance, based on substrate conversion in the permeate. Long-term operation and storage indicate a remarkable kinetic stability of the immobilized cells.
