Enhanced transmembrane electron transfer in <i>Shewanella oneidensis</i> MR-1 using gold nanoparticles for high-performance microbial fuel cells

Abstract

, which was 17.4 times higher than that with the native bacteria, reaching the highest performance yet reported in MFCs using Au or Au-based nanocomposites as the anode. This work elucidates the role of Au nanoparticles in promoting transmembrane and extracellular electron transfer from the perspective of molecular biology and electrochemistry, while alleviating bottlenecks in MFC performances.
