Abstract

Key findings

  • The presence of Geobacter sulfurreducens on gold single crystal electrodes leads to the formation of a biofilm with a specific structural arrangement.
  • The biofilm structure is influenced by the electrode surface roughness and the presence of specific functional groups.
  • The study provides evidence for the role of redox proteins in mediating the bioelectrochemical interactions between Geobacter sulfurreducens and gold electrodes.
