Inactivation of Bacillus subtilis Spores by Ultraviolet and Solux LightingPublic
Downloadable Contentopen in viewer
An intentional outbreak of anthrax (Bacillus anthracis) created a scare that forced an increasing awareness of this bacterial pathogen. This MQP used a bacterium of the same genus, Bacillus subtilis, to determine whether the use of ultraviolet light and simulated sunlight (Solux) would be able to inactivate the spores after various lengths of time, ranging from two minutes to forty-eight hours. The results showed that both sources of light were successful in the inactivation of B. subtilis spores.
