Study Comparing Surface Disinfecting Efficacy of Vacuum UV-Amalgam Lamp and Low Pressure Mercury UV Amalgam Lamps
Young-Ju Kim et. al. Full PDF available at: https://tinyurl.com/22bo6ygq Abstract The objective of this study was to investigate the inactivation mechanism of a vacuum-ultraviolet (VUV)-amalgam lamp and its bactericidal efficacy on a stainless-steel surface and water compared with that of a conventional low-pressure mercury ultraviolet (LP) lamp. When treated with the VUV-amalgam and LP lamp over distilled water, initial 6–7 log CFU/mL of the foodborne pathogens (Escherichia coli O157:H7, Salmonella Typhimurium, and Listeria monocytogenes) were inactivated over 4.5 log after 60 mJ/cm2 treatment. However, there was no significant difference (p > 0.05) from the action of the VUV-amalgam lamp and conventional LP lamp at the same dose.…
