The aim of this study was to assess the antimicrobial efficiency of a photoactivated chlorophyllin-chitozan complex against the food pathogen Salmonella enterica. Salmonella enterica was used for experiments. Aliquots of bacterial suspensions (~1×10 7 CFU/ml in 0.9 % NaCl) with 0.001 % chlorophyllin-0.1 % chitosan complex (Chl-CHS) were incubated in the dark at 37 C for 0-120 min. For the photoactivation, the samples were exposed to light (λ = 405 nm) for 30 min (light dose 17.3 J/cm 2 ).doi:10.5755/j01.ct.61.3.2710 fatcat:nlprnj3k6jdw5ht5bimv5ldkre
