Influence of cold stress (4°C) on ACP inactivation efficacy for L. monocytogenes EGD-e (WT) and its mutant strains (Inline graphic, untreated control; Inline graphic, cultures exposed to cold stress for 1 h; Inline graphic, 1 min ACP; Inline graphic, 1 min ACP to cultures exposed to cold stress). Experimental conditions: 1 min of direct plasma treatment at 80 kV following 1 h of Post treatment storage time. SD, standard deviation; ND, Non-detectable. Limit of detection was 1.0 Log10 CFU/ml.
