Survival rate of B. subtilis spores for the indicated time under dark conditions after the treatment, either of commercially available peracetic acid (PAA) solution at various concentrations (15, 150, 500, 1000, or 1500 ppm) or of WO3 suspended in ethanol:water solution (8:2, v/v) after 12 h of visible light irradiation.
Photocatalyst: 25 mg, light source: Xe lamp (vis) with L-42 filter (λ > 420 nm), liquid-phase volume: 50 mL, density of B. subtilis spores: 2.0 × 106 CFU/mL.
