a Images of S. aureus colonies formed on LB agar plates after different treatments. The images are representatives of three independent experiments with similar results. b Viability of S. aureus treated with different concentrations of HiZP. (c) Absorption spectra produced by the addition of free ATP, fresh medium without S. aureus and culture medium with S. aureus. d Emission spectra of DCF in the presence of mixtures of HiZP and the supernatants of bacteria treated with different concentrations of iodoacetic acid. e Time-dependent viability of S. aureus treated with the free HRP/IAA system and HiZP. The antibacterial activities of HiZP and the free HRP/IAA system against S. aureus before and after treatment with (f) excess trypsin and (g) after storage for 14 days at room temperature. Data are presented as mean values ± SD (n = 3 independent experiments). Statistical significance was analyzed via one-way ANOVA with Tukey’s multiple comparisons test.
