Survival of biofilm after UVB or UVA LED exposure, the level of exposure was equivalent to what can be received by sunlight. The photon rate delivered on the biofilms by the UVB and UVA LEDs was 0.0495 mol/m2, corresponding to a radiant exposure 17.500 J/m2 to 21.100 J/m2. The biofilms were P. aeruginosa and grown for 24 h. The peculiar observation indicated by the black arrow led us to perform several repetitions of this specific treatment; all repetitions resulted in log eradication higher than 8. The dashed box comprises measurements corresponding to zero counts. The measurements in the dashed box in Fig. 2 correspond to zero counts, i.e. complete eradication of the biofilm.
