Abstract

A novel synthetic polymer (ethylene-vinyl acetate copolymer; EVA) was used to immobilize acclimated sewage sludge for H₂ production under anaerobic conditions. Using sucrose as the sole carbon substrate, the resulting EVA-immobilized cells achieved an optimal H₂ production rate (vH2) of 488 ml H₂/g VSS and the best substrate-based yield (YH2/sucrose) of 1.74 mol H₂/mol sucrose. Operation at a temperature of 40 °C resulted in the most efficient H₂ production. Acclimation of the sewage sludge allowed up to 3-fold enhancement on the performance of H ₂ production. Kinetic studies show that a Monod-type model is able to describe the dependence of specific H₂ production rate on sucrose concentration. The immobilized cells maintained stable and efficient H ₂ production during 15 repeated runs, indicating excellent durability and stability of the immobilized-cell system. The composition of soluble metabolites was found to be a reliable indicator for the efficiency of biohydrogenation.
