Title: Synergistic Hydrogen Production in a Biorefinery via Bioelectrochemical Systems

Microbial electrolysis cells are devices that use biocatalysis and electrolysis for production of hydrogen from organic matter. Biorefinery process streams contain fermentation by products and inhibitors which accumulate in the process stream if the water is recycled. These molecules also affect biomass to biofuel yields if not removed from the recycle water. The presence of sugar- and lignin- degradation products such as furfural, vanillic acid and 4-hydroxybenzaldehyde has been shown to reduce fermentation yields. In this work, we calculate the potential for hydrogen production using microbial electrolysis cells from these molecules as substrates. Conversion of these substrates to electricity is demonstrated in microbial fuel cells and will also be presented.
