Ultraviolet Light - resistance

Resistance to ultraviolet light (UV-resistance) is the ability of a bacterial species to grow in the presence of ultraviolet light that would normally be detrimental to the cell. Like in humans (think sunburn and skin cancer) ultraviolet light is harmful to bacteria, the light can cause mutations in the genetic code of the bacterium that can be detrimental to the bacterium's survival. Interestingly one of the mechanisms that protects the microbial cell is the same that protects humans, the production of melanin.
