摘　　要：为观察二氯一溴异氰尿酸对枯草杆菌黑色变种芽胞的杀灭效果及其影响因素，进行了载体定量杀菌试验。结果，以含有效氯１００ ｍｇ／Ｌ的二氯一澳异氰尿酸溶液作用１０ｍｉｎ，对布片上枯草杆菌黑色变种芽胞的杀灭率达１００％。在消毒液ｐＨ４．０～８．０时，以ｐＨ４．０时杀菌效果较好，随ｐＨ上升杀菌效果明显下降。小牛血清对其杀菌作用有明显影响。该化合物为杀菌作用受有机物与溶液ｐＨ影响的杀芽胞剂。In order to observe the efficacy of dichloro-monobromo-isocyanuric acid in killing spores of Bacillus subtilis var. niger and its influencing factors, carrier quantitative bactericidal test was carried out. The results showed that the solution of dichloro-monobromo-isocyanuric acid containing available chlorine 100 mg / L with a 10 min contact time killed 100% of the spores of Bacillus subtilis var. niger on the cloth strip. Among the disinfectant solutions with pH 4.0-8.0, the solution with pH 4.0 showed the best bactericidal efficacy and the bactericidal efficacy decreased obviously with increasing pH. Calf serum influenced significantly its bactericidal efficacy. This compound is a sporicide with its bactericidal efficacy being influenced by the organic substance and pH of the solution.
