Table 1 CFU/filter values of P. aeruginosa biofilms after different treatments and the ones of untreated reference samples. P. aeruginosa biofilms grown by 24 h and 48 h were investigated. ‘24 hours’ and ‘48 hours’ refer to the biofilm state; ‘1’, ‘2’, ‘3’ refer to the biological replicates; ‘treat’ refers to the CFU/filter value after irradiations; and ‘ref’ refers to the CFU/filter value without treatment, as reference sample.
