The Role of Reactive Oxygen Species in Near-Ultraviolet (320-400 NM) Light Inactivation of Escherichia Coli
The biological effects of near-UV (320-400 nm; UV-A) radiation are still poorly understood. It has been clearly established, however, that the mechanism of inactivation by these wavelengths differ from that of far-UV (200-290 nm) radiation. The involvement of oxygen in the near-UV inactivation processes lead investigators to suggest that oxygen reactive species such as singlet oxygen and superoxide anion produced during exposure to near-UV.
