摘要:

研究松萝酸对金黄色葡萄球菌、短链芽孢杆菌、枯草芽胞杆菌、苏云金杆菌、大肠杆菌的抑菌作用,并将其抑菌效果与苯甲酸和山梨酸对比。结果表明,松萝酸的抑菌效果强于苯甲酸和山梨酸;对苏云金杆菌、金黄色葡萄球菌、枯草芽杆菌、短链芽孢杆菌、大肠杆菌的最小抑制浓度分别为0.500、0.557、0.557、0.525、1.76mg/ml,对它们的抑菌能力由大到小为:金黄色葡萄球菌>短链芽孢杆菌>枯草芽孢杆菌>苏云金杆菌>大肠杆菌。

Abstract:

In this study, the inhibitory effects of usnic acid against Staphylococcus aureus, short-chain Bacillus, Bacillus subtilis, Bacillus thuringiensis and E. coli were investigated, and the bacteriostasis of usnic acid was compared with that of benzoic acid and sorbic acid. The results showed that the bacteriostasis of usnic acid is superior to that of benzoic acid and sorbic acid; the minimal inhibitory concentrations (MIC) of usnic acid against these bacteria are 0.557, 0.525, 0.557, 0.500 and 1.76 mg/ml, respectively; the inhibitory effects of usnic acid against these bacteria decrease in the following order: Staphylococcus aureus > short-chain Bacillus > Bacillus subtili >Bacillus thuringiensis > E. coli.

Key words: usnic acid, bacteriostasis, antibacterial capacity
