Abstract

ABSTRACT Here, we show that resistance of Escherichia coli to TiO 2 photocatalysis involves defenses against reactive oxygen species. Results support the idea that TiO 2 photocatalysis generates damage which later becomes deleterious during recovery. We found this to be partly due to DNA attack via hydroxyl radicals generated by the Fenton reaction during recovery.
