Filter pair 1 (544/650 nm) detects fluorescence of the indicator dye. The second filter pair (544/590 nm) measures fluorescence of the reference dye. All experiments were repeated on independent days. Oxygen concentration as percentage air saturation was calculated for each well by using the following equation:
  • Biofilms of Pseudomonas aeruginosa ATCC 15442 were formed on an Oxoplate® after 48h at 30°C, once the biofilms were rinsed with PBS 1 X twice they were incubated for half an hour under different treatments as follows:
