Coupling of microbial electrolysis cells and dark fermentation to enhance the production of hydrogen from agro-industrial wastewaters

Abstract : The aim of this work is the development of a feasible, cascade two-step BioH2 production process from Organic Wastewater (WW), combining dark fermentation (DF) and Microbial Electrolysis Cells (MECs). Such coupling of DF and ME constitutes a technological cornerstone within the concept of an environmental biorefinery. Five different WW coming from cheese (CW), fruit juice (FJW), paper (PW), sugar (SW) and fruit processing (FPW) factories were selected among 21 different WW collected from a wide range of industrial sectors (food, manufacturing, biofuel, wastewater treatment, among others) to evaluate the feasibility of two-step process. The results of this work show that dark fermentation linked with ME is a feasible and highly promising option in order to maximize the conversion of WW into bioenergy.
