Abstract

Microbial fuel cells (MFCs) operating with complex microbial communities have been extensively reported in the past, and are commonly used in applications such as wastewater treatment, bioremediation or in-situ powering of environmental sensors. However, our knowledge on how the composition of the microbial community and the different types of electron transfer to the anode affect the performance of these bioelectrochemical systems is far from complete. To fill this gap of knowledge, we designed a set of three MFCs with different constrains limiting direct and mediated electron transfer to the anode.

Key findings

  • Microbial fuel cells with different electron transfer mechanisms exhibit distinct electrochemical performance and microbial community profiles.
  • The study identifies a correlation between electron transfer mechanisms and microbial community composition.
  • The results suggest that understanding electron transfer mechanisms is crucial for optimizing microbial fuel cell performance.
