Antibiofilm Effects of Malic Acid Treatments on S. Aureus Biofilms

Abstract

In this study, antibiofilm activities of malic acid treatments on S. aureus biofilmswere investigated. The reduction ratios of biofilms by malic acid treatments were compared with chlorine treatment. The effects of sanitizers on biofilms were evaluated on both on polystyrene and stainless steel surfaces. Malic acid treatment more efficiently inhibitedand removed S. aureus biofilms than chlorine treatment. The higher reduction ratios were obtained on stainless steel surfaces. The results show that malic acidcould be a potential promising ecofriendlytreatment for biofilm formations in food contact surfaces.
