dc.description.abstract | The purpose of this study was to compare the degree of microbial inactivation and cell damage induced by intense pulsed light (IPL) and short-wavelength ultraviolet (UVC) in Listeria monocytogenes and Escherichia coli O157:H7. The viability of the food-borne pathogens treated with IPL and UVC (254 nm) decreased exponentially with treatment time. Particularly dramatic reductions in L monocytogenes and E. coli O157:H7 were observed for IPL treatments at energy densities of 376 and 455 W/m(2), with an approximately 7-log reduction for a treatment time of 60-180 s. Also, a 4-fog reduction of L monocytogenes and a 5-log reduction of E. coli O157:H7 were achieved with UVC irradiation for 1200 s. The types and amounts of IPL- and UVC-induced DNA damage in both microorganisms were determined and compared. DNAs from cells irradiated with either IPL or UVC accumulated double-strand breaks (DSBs), single-strand breaks, and cyclobutane pyrimidine dimers, and with a similar pattern: however, more DSBs were detected following UVC than following IPL in both types of microorganism. Transmission electron microscopy observations of IPL- and UVC-induced cell damage clearly indicate that bacterial cell structures were destroyed by IPL treatment but not by UVC treatment.
