摘要

加热生物壳氧化钙(BiSCaO)粉末悬浮液(pH 12.4)、次氯酸(HClO;pH 6)，次氯酸钠(NaClO;比较有机物污染环境下的pH值为8)、聚维酮碘(Isodine溶液®)和葡萄糖酸氯己定(hibisrub®)，对与正常菌群(总活菌数和大肠菌群)孵育的木屑和猪皮片进行检测。实验结果表明，BiSCaO悬浮液的杀菌活性高于HClO和NaClO。此外，为了达到与BiSCaO悬浮液相当的杀菌活性，需要使用浓度高出10倍以上的防腐剂，如聚维酮碘和葡萄糖酸氯己定。我们的研究结果表明，在有机物污染的环境中使用BiSCaO悬浮液作为环境和食品卫生消毒剂的可能性。

Comparison of Various Disinfectants on Bactericidal Activity Under Organic Matter Contaminated Environments.

The bactericidal activity of heated bio-shell calcium oxide (BiSCaO) powder suspension (pH 12.4) , hypochlorous acid (HClO; pH 6), sodium hypochlorite (NaClO; pH 8) , povidone-iodine (Isodine solution^®) , and chlorhexidine gluconate (Hibiscrub^®) under organic matter contaminated environments were compared for tests conducted on wood scraps and pig skin pieces that were incubated with normal bacterial flora (total viable counts and coliform bacteria) . The test results showed that BiSCaO suspension had higher bactericidal activity than HClO and NaClO. Furthermore, more than 10-fold higher concentrations of antiseptics such as povidone-iodine and chlorhexidine gluconate were required to achieve bactericidal activity comparable to that of BiSCaO suspension. Our results demonstrate the possibility of using BiSCaO suspension under organic matter contaminated environments as a disinfectant for environmental and food hygiene applications.
