| Description | The ability of bacteria to form a biofilm has a negative effect for a number of industries including the meat industry. In the meat industry the biofilm is a continuing source of contamination of microorganisms which are involved in causing alimentary infections and food spoilage. The aim of this pilot study was to test the effect of sub-lethal concentrations of the three currently used disinfecting agents in the food industry for ability to induce biofilm formation by strains of Escherichia coli and Staphylococcus aureus isolated from meat establishments. We tested these disinfectants: benzalkonium chloride (BAC), ethanol and peracetic acid. Induction of biofilm formation was monitored by measuring the fluorescence signal after staining dye SYTO9. Induction of S. aureus biofilm formation was observed in the cultivation with 4x10-4% BAC; 1.25% ethanol and 3x10-5% peracetic acid and in the case of E. coli with 2x10-8% BAC; 5% ethanol and 3x10-6% peracetic acid. These measurements confirmed that low concentrations of disinfectants can induce the biofilm formation by strains of E. coli and S. aureus. |
