Effect of start-up strategies with functionally redundant and efficient electroactive bacteria on the performance of microbial electrolysis cells fed with domestic wastewater

Enriching functionally redundant and efficient (i.e., high-current producing) acetoclastic electroactive bacteria (EAB) in the anodic biofilm of microbial electrolysis cells (MECs) is crucial for its application in wastewater treatment with resource recovery. Here, we investigated the effect of different start-up strategies for enriching anode biofilms with functionally redundant and efficient EAB on the performance of wastewater-fed MECs .
