文摘

460 nm LED illumination effectively reduced the populations of foodborne pathogens. In general, inactivation rate in PBS was higher at 25 °C compared to 4 and 10 °C. LED illumination induced significant sub-lethal injury into foodborne pathogens. Several ROS precursors and scavengers were differentially regulated in bacteria.
