Use of non-native phenazines to improve the performance of Pseudomonas aeruginosa MTCC 2474 catalysed fuel cells

► Addition of non-native phenazines improved the Pseudomonas aeruginosa 2474 catalysed MFC. ► Native phenazines inhibited microbial growth and MFC power generation. ► With Cu2+-GECE (anode) in oxychloraphin supplemented MFC, power output was 7.8 mW/m2.
