二溴海因化学名称为1,3-二溴-5,5-二甲基海因,是二甲基乙内酰脲的一种卤化衍生物,对细菌、真菌和病毒具有广谱的杀灭作用。宏达海因消毒粉剂(天津宏达利德科技发展有限公司生产)以二溴海因为主要有效成分,呈淡黄色粉末状,有轻度刺激气味,有效溴含量为质量分数25.95%。为观察该消毒粉剂的杀菌效果,进行了本实验室研究。现将结果报告如下。1方法1.1菌悬液制备取大肠杆菌(8099)、金黄色葡萄球菌(ATCC6538)24h新鲜培养物,以稀释液洗下细菌并配制成使用浓度的菌悬液;将枯草杆菌黑色变种(ATCC9372)芽孢用同样的稀释液配制成芽孢悬液。1.2中和剂选择实验实验菌为大肠杆菌、金黄色葡萄球
The chemical name for dibromohexine is 1,3-dibromo-5,5-dimethylhydantoin, a halogenated derivative of dimethylhydantoin with a broad spectrum of killing of bacteria, fungi and viruses Off effect. Hongda Haine disinfection powder (Tianjin Hongda Lide Technology Development Co., Ltd.) to dibromo sea as the main active ingredient, was light yellow powder, mild irritating odor, the effective bromine content of 25.95% by mass. In order to observe the bactericidal effect of the disinfectant, the laboratory study was conducted. The results reported below. 1 Method 1.1 Preparation of bacterial suspension Preparation of E. coli (8099), Staphylococcus aureus (ATCC6538) 24 hours of fresh culture, the dilution of bacteria was washed and formulated to use the concentration of bacterial suspension; Bacillus subtilis black variant (ATCC9372) Spores were spiked with the same dilution. Neutralizer selection experiment Experimental bacteria Escherichia coli, Staphylococcus aureus
