Pathogen analysis. For each pathogen, the percentage of surviving bacteria on the C150 and C200 substrates was normalized to that on the UV100 substrates. Illumination was performed at light density of 3 × 104 lux for 10 min. * P < 0.05 and ** P < 0.01 compared to the respective UV100 groups. + P < 0.05 compared to the respective C150 groups.
