Deleterious effect of homogeneous and heterogeneous near-neutral photo-Fenton system on Escherichia coli. Comparison with photo-catalytic action of TiO2 during cell envelope disruption

- Comparison of cell envelope disruption by photo-Fenton and TiO2 photocatalysis.
- Internal and external (photo)-Fenton process contributed to Escherichia coli inactivation.
- E. coli inactivation by homogeneous and heterogeneous photo-Fenton process.
- An overall bacterial inactivation mechanism by photo-Fenton process is proposed.
