Abstract

Photoreactivation is a process that generates repair of ultravioletradiation (UV) damage in micro-organisms. Repair involves the DNA photolyase enzyme, which uses energy provided by light of wavelengths between 300 and 450 nm to reverse many types of DNA damage. Most studies of photoreactivation have relied on irradiation with continuous-wave (CW) light. This study examines the repair of UV-induced damage using both CW light from a bank of fluorescent lamps in a light cabinet, and pulsed light provided by a xenon flashlamp.
