Abstract

Key findings

  • The model showed that extracellular electron transfer plays a crucial role in the corrosion process.
  • The presence of sulfate-reducing bacteria in the biofilm significantly increased the corrosion rate.
  • The model predictions were validated with experimental data, demonstrating its accuracy in simulating microbial corrosion.
