Table 1 Minimum Inhibitory Concentration of H2O2 and carotenoid content of Staphylococcus aureus following different culture conditions

From: Assessment of the potential for resistance to antimicrobial violet-blue light in Staphylococcus aureus

Growth Conditions Average Minimum Inhibitory Concentration of H2O2 (%) ± SD Average Carotenoid Absorbance at 465 nm ± SD
Complete Darkness 0.00293 ± 0.00000 0.90 ± 0.22
White Lighting 0.00513 ± 0.00146 0.82 ± 0.24
Low irradiance (1 mW/cm2) 405 nm Light 0.01831 ± 0.01025* 0.17 ± 0.12*
  1. Differences in the minimum inhibitory concentration (MIC) of hydrogen peroxide (H2O2) and carotenoid content of methicillin-sensitive Staphylococcus aureus when cultivated in different lighting conditions. Data points represent the mean count (n = 3) ± SD
  2. *represents a significant change (P < 0.05)
