The neutralizing effect of C6-AHL autoinducer with 3-methyl-2(5H)-furanone (G2). The biofilm was formed for 30 h at 37 °C with the addition of the compounds from the beginning of the assay. The biofilm was quantified by staining with violet crystal. The black asterisks indicate statistically significant difference to the control, whereas the red asterisks indicate statistically significant difference as compared to C6-AHL.
