title: Effects of UV radiation on photolyase and implications with regards to photoreactivation following low- and medium-pressure UV disinfection.
abstract: Photolyase activity following exposure to low-pressure (LP) and medium-pressure (MP) UV lamps was evaluated. MP UV irradiation resulted in a greater reduction in photolyase activity than LP UV radiation. The results suggest that oxidation of the flavin adenine dinucleotide in photolyase may have caused the decrease in activity.
