Removal of Typhimurium Biofilm from Food Contact Surfaces Using Gall Extract in Combination with a Surfactant.

(nutgall) has been reported to possess antimicrobial activities against a wide range of pathogens. Nevertheless, the biofilm removal effect of nutgall extract has not been widely investigated. In this study, we therefore evaluated the effect of nutgall extract in combination with cetrimonium bromide (CTAB) against preformed biofilm of Typhimurium on polypropylene (PP) and stainless steel (SS) coupons in comparison with other sanitizers.
