Figure 1

Inactivation of E. coli, L. monocytogenes, S. Typhimurium, P. aeruginosa, S. aureus in 1.2-mm thick liquid suspension by exposure to continuous 405 nm LEDs of an irradiance of approximately 0.5 mW/cm2. Data points represent means and error bars represent one standard deviation (n = 3). The blue dotted line denotes the limit of detection (LOD). Asterisks denote data points that are significantly different from the others at the same 405 nm LED exposure doses (p < 0.05), whereas circles denote clusters of data points that are not significantly different within the circle (p > 0.05). Circles of different colors indicate data points are significantly different between two circles at the same 405 nm LED exposure doses (p < 0.05).
