Inhibition of Listeria monocytogenes by resident biofilms present on wooden shelves used for cheese ripening

摘要: Abstract The purpose of the present study was to characterize development Listeria monocytogenes on wooden shelves used for cheese ripening. fate two L. strains analysed over time as a function presence native biofilm, farmhouse origin cheeses, and properties. In microbial flora shelves, deposited populations L. monocytogenes remained stable or even decreased by up 2 log10(CFU/cm2) after 12 days incubation at 15 °C in all tested conditions. By contrast, increased 4 when resident biofilm thermally inactivated, suggesting observed inhibitory effect. All together, our results suggest that biocontrol pathogens multiplication biofilms should be considered microbiological safety traditional ripened cheeses.
