目的研究酸性硫酸钙(ACS)杀灭微生物的效果。方法采用悬液定量杀菌试验方法,对酸性硫酸钙杀灭微生物的效果进行了实验室观察。结果 ACS以800倍稀释液作用10 min,对铜绿假单胞菌的杀灭对数值为6.48;以400倍稀释液作用30 min,对金黄色葡萄球菌的杀灭对数值为5.98;以200倍稀释液作用20 min,对大肠杆菌的杀灭对数值为6.17;以100倍稀释液作用30 min,对脊髓灰质炎病毒灭活对数值≥4.00。结论 ACS对细菌繁殖体和病毒均有良好的杀灭效果。
Objective To study the effect of acidic calcium sulfate on killing microorganisms. Methods Suspension quantitative germicidal test method, the effect of acid calcium sulfate to kill microorganisms were observed in the laboratory. The results of ACS 800-fold dilution for 10 min, the killing logarithm of Pseudomonas aeruginosa was 6.48; with 400-fold dilution for 30 min, the killing logarithm of Staphylococcus aureus was 5.98; 200 times Dilution of 20 min, killing E. coli logarithmic value of 6.17; with 100-fold dilution for 30 min, the inactivation of polio virus logarithm value ≥ 4.00. Conclusion ACS has a good killing effect on both bacterial propagules and viruses.
