Abstract
Key findings
- Pseudomonas aeruginosa biofilm accelerates corrosion of 304 stainless steel by 2.5 times compared to non-biofilm controls.
- Outward extracellular electron transfer is identified as the primary mechanism of corrosion acceleration.
- Corrosion rate increases with biofilm thickness and age.
