“…( Xu et al, 2021a , 2022 ). Extracellular polysaccharides, proteins, lipids, and eDNA are the most important components in the formation of the complex biofilm matrix, which provides a protective barrier for bacteria against harsh environments, antimicrobial agents and host immune effects ( Liu et al, 2022b , 2023a , b ; Wen et al, 2023 ). The biofilm cycle consists of three main stages, namely adsorption onto the surface of living or non-living media, biofilm maturation, planktonic cell dispersion.…”

BackgroundPseudomonas aeruginosa (P. aeruginosa) can cause serious infections in many parts of the body and is also an underestimated foodborne pathogen. Intense pulsed light sterilization is recognized for its high sterilization efficiency, flexible and safe operation and ease of installation on production lines, which makes up for the shortcomings of several other physical sterilization technologies.MethodsThis experiment studied the killing efficiency of different capacitances (650 μF, 470 μF, and 220 μF) of intense pulsed light on foodborne pathogenic microorganisms P. aeruginosa in the models of liquid food models, 96-well cell plates, and polycarbonate membrane models at room temperature (25°C) and refrigerated (4°C) environments to provide data to support the application of IPL sterilization devices in food processing.ResultsThe IPL was very effective in killing P. aeruginosa in the planktonic state as well as in the early and mature biofilm states, meeting target kill rates of 100%, 99.99%, and 94.33% for a given number of exposures. The biofilms formed in the polycarbonate membrane model and the 96-well plate model were more resistant to killing compared to the planktonic state. To achieve the same bactericidal effect, the number of flashes increased with decreasing capacitance.ConclusionThe bactericidal effect of IPL on P. aeruginosa was significantly influenced by the state of the bacterium. The larger the capacitance the higher the number of pulses and the better the sterilization effect on P. aeruginosa.
