An effective sporicidal reagent against Bacillus subtilis spores.
We developed a reagent which showed significant sporicidal activity against Bacillus subtilis spores. This reagent was composed of ethylenediaminetetraacetic acid, disodium salt (EDTA-2Na), ferric chloride hexahydrate (FeCl3 x 6H2O) and ethanol (tentatively designated as the ethanol reagent). The ethanol reagent showed pH- and temperature-dependent sporicidal activity. At pH 0.3, its activity was almost the same as that of 0.05% sodium hypochlorite at 20 C and was higher at 37 C than at 20 C. The activity of the ethanol reagent was similar both with and without 10% serum. The ethanol reagent might be applicable for disinfecting Bacillus spores.
