Abstract

The effects of the substrate to inoculum ratio, the distance between the two electrodes and the applied voltage on bio-hydrogen and bio-methane by an integrated process of dark fermentation, microbial electrolysis cell and biomethanisation were investigated in this study. The determination of optimal conditions was performed using full factorial design. The effect of the substrate to inoculum ratio, the distance between the two electrodes and the applied voltage were chosen as independent variables while hydrogen and methane were selected as dependent variables. The optimum substrate to inoculum ratio, distance, and voltage resulting in the highest bio-hydrogen (1492.23 ml) and methane volume (1775.4 ml) were 1.5, 3 cm and 0.6 V, respectively.
