Number of viable cells of S. aureus ATCC 25923, P. aeruginosa ATCC 27853 and the clinical isolate P. aeruginosa 19595, after 4 h of treatment with b-LED (blue bars). Controls were untreated samples at time 0 (black bars) and 4 h (grey bars). The data reported are the mean ± standard deviation (SD) of three independent experiments. The level of statistical significance between samples was determined by the multiple t test (GraphPad Prism v.8.0.1, GraphPad Software, La Jolla, CA, USA), and indicated as follows: * p < 0.05; ** p < 0.01; *** p < 0.001 and ns, not significant.
