P. aeruginosa bacteria were allowed to form biofilms in peg plates for 24 h, the medium was removed and fresh medium with different concentrations of radical scavenger compounds were changed every 24 hours over three days (Days 1, 2 and 3). The percentage of biofilm biomass production is represented for each day. The results are the means ± SD of three-five replicates from one representative of two independent experiments. A Student's t-test was performed (*, P < 0.05; versus non-treated biofilms). HU, hydroxyurea; HA, hydroxylamine; and M-HA, methyl- hydroxylamine.
