本文观察了一种戊二醛复方消毒剂对微生物的杀灭效果。结果表明，在试验温度为２０℃，试验用菌悬液中加入１０％小牛血清的条件下，该消毒剂２．００％的稀释液作用２分钟可杀灭９９．９９％的金黄色葡萄球菌，１．００％的稀释液作用２分钟可杀灭９９．９９％的大肠杆菌，原液作用３５分钟可破坏ＨＢｓＡｓ的抗原性；在加热５０℃条件下，原液作用３５分钟，５０．００％的稀释液作用４５分钟可１００％杀灭枯草杆菌黑色变种芽胞。在对该消毒剂的有效抑菌、杀菌和根据能量试验确定的应用浓度比较时发现，杀菌浓度比抑菌浓度高４倍，应用浓度比杀菌浓度高５倍，此结果提示，在消毒试验中，选择适当的中和剂十分重要；消毒剂的实际应用浓度应根据能量试验的结果来确定。
This article observed a glutaraldehyde compound disinfectant on the killing effect of microorganisms. The results showed that under the condition of the test temperature is 20 ℃ and 10% bovine serum was added into the test bacterial suspension, the 2.00% diluted solution of the disinfectant could kill 99.99% golden yellow grape for 2 minutes Cocci, 1.00% dilution of 2 minutes to kill 99.99% of E. coli, the original solution of 35 minutes to destroy the antigenicity of HBsAs; under the conditions of heating 50 ° C, the stock solution for 35 minutes, 50.00% The dilution of the role of 45 minutes to kill 100% Bacillus subtilis black mutant. In the effective inhibition of the disinfectant, bactericidal and energy concentration determined according to the application of the test found that the bactericidal concentration than the bacteriostatic concentration of 4 times higher than the bactericidal concentration of 5 times higher concentration, the results suggest that in the disinfection test , It is very important to choose the appropriate neutralizer; the actual application concentration of disinfectant should be based on the result of energy test.
