Different Patterns of Biofilm Formation and Effect of Sub-MIC Disinfectant on Biofilm Formation of Foodbore Pathogens

Abstract:

The objective of this study is to investigate the biofilm formation of four kinds of different bacteria in vitro under different culture conditions and the effect of sub-MIC disinfectant on biofilm formation.For this,biofilm formation were tested by microtiter-plate method under the different nutrient conditions,temperature and pH,as well as different concentration of quaternary ammonium compounds.the results demonstrated that biofilm formation was identified widely among food pathogens.Furthermore,high temperatures,low concentration of glucose and sodium chloride increased the production of biofilm.From the above results,a conclusion could be made: Biofilm formation was influenced by many factors.Control of the production of biofilm was important for food safety in the food processing.
