peroxyacetic acid or H2O2. For example, the peroxyacetic acidbased sanitizer showed a strong sporicidal effect against Clostridium estertheticumspores (Broda, 2007); however, this was ineffective against B. cereus and Bacillus thuringiensis spores attached to
stainless steel and apples (Kreske et al., 2006). Also, exposure
planktonicBacillusspp. spores to 100,000 ppm H2O2for 1 min at RT
showed a limited sporicidal action (Khadre and Yousef, 2001).
