Biofilm formation with H₂O₂ treatment (range of 2.5 to 30 mM) of strain N° 1. (a) Biofilm biomass units (BBU) (-◆-), relation of ROS and BBU (ROS/BBU) (-■-), and NO and BBU relation (NO/BBU, nitrite expressed in 𝜇M) (-▲-); (b) SOD activity (%)/BBU (-•-); and (c) CAT (U)/BBU (-∘-). Each line shows the mean ± SEM of three independent experiments.
