Abstract

Key findings

  • Geobacter metallireducens and Shewanella algae exhibit distinct carbon isotope signatures in their fatty acids, suggesting differences in their metabolic pathways.
  • The carbon isotope signatures of fatty acids in these bacteria are influenced by their interactions with electrodes, indicating a potential link between microbial metabolism and electrode function.
  • The study's findings have implications for understanding the role of microorganisms in electrode-based systems, such as microbial fuel cells.
