Abstract

Key findings

  • Exposure to copper shock load altered the bacterial community structure and diversity in the microbial fuel cell.
  • Enterobacter strains exhibited increased electron transfer efficiency and biofilm formation in response to copper stress.
  • Copper shock load affected the bacterial metabolic pathways, leading to changes in the production of extracellular polymeric substances.
