Research Abstract |
In order to investigate the physical characteristics of bacterial biofilm, the mechanical properties were evaluated by indentation analysis with spherical probe. The biofilm thickness was calculated by comparison of the compression stiffness between the developed biofilm and polystyrene base. The biofilm with greater hardness were observed from the thinner one. These results could indicate that the smaller biofilm produced on the food and food contacting surface may have strong physical properties, and be difficult to remove by several treatments. Therefore it is suggested that the appropriate removal process should be applied physically, chemically and biologically for ensuring food safety.
