| 摘 要： | 以枯草芽孢杆菌、大肠杆菌和金黄色葡萄球菌为代表,分别探讨了薇甘菊水溶性提取物对上述3种细菌在培养24 h过程中的光密度、活菌数和最低杀菌浓度的影响。试验结果表明,在一定浓度范围内薇甘菊水提物对上述3种细菌均有不同程度的抑制作用。其中,枯草芽孢杆菌的抑制作用最强,其次是大肠杆菌和金黄色葡萄球菌。透射电镜观察结果表明,薇甘菊水提物可抑制金黄色葡萄球菌细胞壁的分离,因而抑制了细胞的分裂而达到抑菌效果。

| Abstract: | The antibacterial effect of water-solubility material extracted from Mikania micrantha was studied by testing the Optical Density value(OD640nm),Colony Forming Unit(CFU) and Minimum Bactericidal Concentration(MBC) of 3 species of bacteria.The results showed that the antibacterial activity of water-solubility extractant resisting Pseudomonas putida was stronger than that of Escherichia coli,Bacillus subtilis and Staphylococcus aureus.The cell division of Staphylococcus aureus was affected by the extraction as observed by electron microscope. |
