摘要: 以不同浓度的水杨酸溶液分别对金黄色葡萄球菌、枯草芽孢杆菌和大肠杆菌进行处理,探讨不同浓度水杨酸溶液对这三种细菌的抑菌效果以及抑菌率。结果表明:水杨酸对金黄色葡萄球菌、枯草芽孢杆菌和大肠杆菌具有明显的抑制作用;而且其抑制作用呈现浓度效应,即随着水杨酸浓度的增大,抑菌效果越来越明显,水杨酸对金黄色葡萄球菌的抑制作用最强,对枯草芽孢杆菌的抑制作用稍差,对大肠杆菌的抑制作用相对最弱。

Abstract: Staphylococcus aureus,Bacillus subtilis, Escherichia.coli were treated by salicylic acid with different concentrations,discussed inhibitory effect and calculated the rate of inhibition with the different concentrations of the salicylic acid solution. The result showed that: The salicylic acid has the very obvious inhibitory effects to Staphylococcus aureus,Bacillus subtilis, Escherichia.coli; Moreover its inhibitory effects presents the density effect. The bacteriostasis effect is getting more and more obvious with the concentration increase of salicylic acid. The inhibitory effect is strongest to Staphylococcus aureus,and second to Bacillus subtilis, and weakest to Escherichia.coli.
