Spores of Bacillus subtilis SA22, harvested from nutrient agar after 9 d at 30°C and stored in distilled water at 4°C, were unaltered in their resistance to 17.7% hydrogen peroxide or 0.04% peracetic acid after storage for up to 134 weeks. Three spore crops of B. subtilis globigii were unaffected by storage for up to 134 weeks with respect to 17.7% hydrogen peroxide resistance but were significantly more resistant to 0.04% peracetic acid following storage.
