Eradicating effect of l-tyrosine on preformed biofilms of PA-02 and SA-04 strains. Biofilm biomass measured by crystal violet staining (A, B). Biofilm viability measured by XTT assay (C&D). The values represent the mean of three independent replicates, with error bars representing the standard deviation of differences that are statistically significant at ^*P ≤ 0.05, ^**P ≤ 0.01, ^***P ≤ 0.001, and ^****P ≤ 0.0001, while P > 0.05 is non-significant (ns)
