  • Bugs Killed by Medium Pressure UV Stay Dead

    It is well known that bacteria and other microorganisms contain enzymes that can repair UV-damaged DNA, a process known as 'reactivation'. Some of these enzymes need visible light to perform the repairs ('photoreactivation'), while others can do so without light (known as 'dark repair'). Photoreactivation is generally quicker than dark repair, but both of these phenomena pose obvious problems ...
