Bio-electrolytic conversion of acidogenic effluents to biohydrogen: An integration strategy for higher substrate conversion and product recovery

► Dark fermentative acidogenic effluents as substrate in MEC process. ► Integration strategy employed resulted additional treatment along with biohydrogen. ► 50% Utilization of volatile fatty acids. ► Bioelectrokinetics of the biocatalyst was studied using Tafel slope analysis. ► Microbial community analysis by DGGE depicted γ-proteobacteria and Firmicutes.
