Figure 7

Biofilm inhibition by quorum sensing inhibitors (QSIs). Obvious biofilm inhibition was observed when treated with butein (B), C7X, C30 and sappanol (S) using FITC-CoA staining dye, compared to the control (C) where there is abundance of biofilm. Butein reduced the biofilm to the maximum when compared to the C30.
