摘要
试验表明，５０％过氧化氢与０５％戊二醛协同作用１０～３０ｍｉｎ，对枯草杆菌黑色变种芽胞的杀灭率远高于单以过氧化氢或戊二醛作用者。戊二醛浓度对复方杀菌效果影响较大，过氧化氢浓度者次之。
The germicidal efficacies of hydrogen peroxide alone, glutaraldehyde alone and their combination were compared experimentally using spores of Bacillus subtilis var niger and the influences of their concentration and pH of their solution on germicidal efficacy were observed in laboratory The results indicated that the killing rates of B subtilis var niger spores exposed to 5 0% hydrogen peroxide, 0 5% glutaraldehyde and their combination for 30 min were 60 12%, 88 18% and 99 99% respectively The range obtained from orthogonal test indicated that the concentration of glutaraldehyde influenced considerably the synergetic germicidal efficacy, the influence of concentration of hydrogen peroxide was the next and pH change of the solution ranging from 3 0～9 0 exerted little influence
