摘要:

旨在研究天然植物精油的抑菌活性及其与过硫酸氢钾复合盐的协同抑菌效果。采用微量肉汤稀释法检测8种植物精油和过硫酸氢钾复合盐对金黄色葡萄球菌ATCC 29740和大肠杆菌CVCC 1450的最低抑菌浓度(MIC)和最低杀菌浓度(MBC),并使用药敏片法检测体外抑菌活性。通过时间-抑菌曲线分析不同精油浓度对细菌生长的动态抑制作用。采用棋盘法结合FIC指数研究精油与过硫酸氢钾复合盐的协同抗菌效果。结果显示,在8种植物精油中,国产薰衣草和澳洲薰衣草精油对金黄色葡萄球菌的MIC最低,为1.95 μg·mL-1,国产洋甘菊和国产薰衣草精油对大肠杆菌的MIC最低,为15.63 μg·mL-1。联合抑菌结果表明,国产洋甘菊精油与过硫酸氢钾复合盐的协同抑菌效果最佳,FIC指数为0.5。本研究筛选出的4种高抑菌性植物精油对动物常见病原菌具有良好的抑制活性,复配过硫酸氢钾复合盐可有效降低对金黄色葡萄球菌ATCC 29740和大肠杆菌CVCC 1450的MIC;国产洋甘菊精油-过硫酸氢钾复合盐组合具有协同抑菌作用,可为天然安全消毒制剂的开发提供参考。

Abstract:

The aim of this study was to investigate the antibacterial activity of natural plant essential oils and the synergistic effect combined with potassium monopersulfate. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of eight essential oils and potassium monopersulfate against Staphylococcus aureus ATCC 29740 and Escherichia coli CVCC 1450 were detected by the micro broth dilution method. In vitro inhibitory activities were detected by using the disc diffusion method. The dynamic inhibitory effects of different essential oil concentrations on bacterial growth were analyzed by time-inhibition curves.The synergistic antimicrobial effects of essential oils and potassium monopersulfate were investigated using the checkerboard method combined with the FIC index.The results indicated that the essential oils of domestic lavender and Australian lavender exhibited the lowest MIC (1.95 μg·mL-1) against Staphylococcus aureus, while the essential oils of domestic chamomile and domestic lavender demonstrated the lowest MIC (15.63 μg·mL-1) against Escherichia coli. The evaluation of the joint antibacterial effect indicated that the essential oil of domestic chamomile, in combination with the potassium monopersulfate, exhibited a synergistic antibacterial effect, with an FIC index of 0.5. In this study, the four highly bacteriostatic plant essential oils under examination exhibited promising inhibitory activity against animal pathogens. Potassium monopersulfate's combination effectively reduced the MIC of Staphylococcus aureus ATCC 29740 and Escherichia coli CVCC 1450, and the combination of domestic chamomile essential oil and potassium monopersulfate exhibited a synergistic effect. These findings provide a valuable reference for the development of natural and safe disinfectant preparations.
