| Popis: | Summary The objective of this study was to investigate the inhibitory effect of Zataria multiflora boiss essential oils (ZEOs), ultraviolet (UV) radiation and their combination against Listeria monocytogenes biofilm in a simulated industrial model (SIM). The effect of minimal inhibitory concentration (MIC) and sub-MIC concentration of ZEOs, different contact time of UV and their combination was evaluated in a SIM on 6- and 12-day-old L. monocytogenes biofilm. In a SIM, 0.3% ZEOs were adequate to completely eliminate 6- and 12-day-old biofilm grown on stainless steel coupons. The population of viable L. monocytogenes biofilm cells under a 15- to 45-min contact time of UV treatment declined significantly at 6- and 12-day-old biofilm. The combined effect of ZEO and UV showed antagonist effects. These findings indicated that in the single use, ZEO and UV revealed a suitable antilisteria biofilm activity, while combining them is not a promising method to remove listeria biofilms from stainless steel surfaces. |
