The opportunity to resort to a two step process in order to overcome part of the bottlenecks of enzymatic hydrolysis of lignocellulosic biomass was examined and preliminary results of an experimental investigation are presented. The bioconversion of a very abundant cellulosic material, wheat straw and the subsequent conversion of the oligosaccharides, mainly cellobiose, were separately studied in two membrane reactors, not intercommunicating each other, and the rate of sugar production and glucose selectivity were monitored as function of using composites of cellulases from T. viride and A. niger. Cellulases from A. niger were physically immobilized in a gel layer of polyalbumin and the operational thermal stability of the B-glucosidase component was studied. Glucose inhibition was compared for the two situations of free and immobilized biocatalyst. INTRODUCTION. MATERIALS AND METHODS. SOLUBLE PHASE REACTION. IMMOBILIZED ENZYME REACTOR.
