Microbial community analysis of the collected microbial samples from anodic and cathodic biofilm, planktonic culture, and inoculum. (a) Jaccard clustering results of bacterial communities defined at 0.03 distances, and (b) microbial community composition at phylum level. Phyla accounting for less than 1% of the total composition in all four libraries were classified as others. *P <0.05, **P <0.01, ***P <0.001.
