Abstract :
The endospores produced by Bacillus spp. are known to be highly resistant to most disinfection methods. Due to their extreme resilience, spores of several Bacillus strains are widely used as biological indicators for sterility testing. In this work, the sporicidal efficacy of a lamp prototype on B. atrophaeus spores is investigated.
