甲醛为高效化学消毒剂,低浓度为抑菌剂,高浓度可作为灭菌剂,其杀菌谱广,对细菌繁殖体、芽胞以及病毒等均有杀灭作用。其作用机理主要靠醛基作用于菌体蛋白(包括酶)的巯基、羟基、羧基、氨基,使之烷基化,可引起蛋白质变性、凝固,造成微生物死亡。但是由于甲醛毒性 Formaldehyde is a highly effective chemical disinfectant, low concentrations of antibacterial agents, high concentration can be used as a sterilizing agent, its broad spectrum of sterilization, the bacteria propagules, spores and viruses kill. Its mechanism mainly depends on the aldehyde group acting on the sulfhydryl, hydroxyl, carboxyl, amino groups of bacterial proteins (including enzymes), alkylation, can cause protein denaturation, solidification, resulting in microbial death. But due to formaldehyde toxicity
