| Abstract: | Abstract— Pre-irradiation of stationary phase cells of Escherichia coli K-12 with broadband near-UV radiation potentiates the lethal effects of subsequent exposure to near-UV radiation plus hydrogen peroxide. Identical fluences failed to modulate killing due to far-UV radiation. These data indicate that biologically revelant levels of hydrogen peroxide may be generated in situ upon the near-UV irradiation of cells. |
