A. Survivor curves for the bacteria exposed to hydrogen peroxide solutions, at 1.5% concentration, the respective decimal reduction times (D-values) were: for Enterococcus cloacae D = 1.8 min (■); Escherichia coli D = 3.2 min () and Staphylococcus aureus D = 3.4 min (□). At 26.5% hydrogen peroxide concentration, Bacillus stearothermophilus, D = 4.7 min (▲). B. Survivor curves for the bacteria exposed to 2% glutaraldehyde solutions, the respective decimal reduction times (D-values) were: for Acinetobacter calcoaceticus D = 4.7 min (■); Enterococcus cloacae D = 6.7 min (*); Escherichia coli D = 7.1 min (); Staphylococcus aureus D = 5.9 min (□); Serratia marcescens D = 5.0 min (+);Bacillus stearothermophilus D = 25 min (▲); Bacillus subtilis D = 25 min ().
