Figure 4. Dose-dependent inhibition of P. aeruginosa biofilms on a biological wound dressing by tryptophan.

Figure 4

Figure 4

The bioloigcal wound dressing was bathed in P. aeruginosa suspended in M63 minimal media supplemented with tryptophan (0 – 10 mM) for 48 hours at 30°C. A) Tryptophan significantly inhibited biofilm formation on the dressing at concentrations above 5mM as determined by crystal violet staining (*, p<0.05). B) Tryptophan significantly decreased bacterial colonization of the dressing at concentrations above 5mM (*, p<0.05).
