Enzymatic hydrolysis of starch has traditionally been performed in large volume batch reactors using soluble enzyme during long time. Introduction of the membrane bioreactor brings possibility of continuous operation in lower volume reactors in shorter reaction time. Studies on the simultaneous enzyme action of glucoamylase and pullulanase on liquefied potato starch in a continuous membrane reactor were made with the application of the various cut-off and transmembrane pressure of membranes. Influence of different reaction conditions namely enzyme concentration, substrate: enzyme ratio and residence time on glucose content were measured. Membrane reactor with 3.000 Da produced almost pure glucose at residence time of 3- 4 h.
