Biomass (OD_570 nm) (a), metabolic activity (OD_490 nm) (b), and number of cells (c) of P. aeruginosa ATCC (light grey) and P. aeruginosa isolated strain (black) biofilms. Biofilms were continuously grown in TSB for 96 h with the application of intermittent cycles for 24 h of 3 mg/mL of CIP (I) and 10 mg/mL GM (II).
