木醋液的抑菌效果比较分析

Comparative Analysis of Antibacterial Effect of Wood Vinegar

以不同精制方法得到的松木屑木醋液、杂木木醋液为原料,分别进行农杆菌(Agrobacterium tumefaciens)、枯草芽孢杆菌(Bacillus subtilis)、金黄色葡萄球菌(Staphylococcus aureus)抑菌实验,研究其抑菌活性。研究结果表明杂木木醋液对3种细菌没有抑菌效果。无水乙醇对3种细菌的抑菌圈均超过25 mm。松木屑木醋液只有体积分数100%浓度对金黄色葡萄球菌(S.aureus)有抑菌作用,抑菌圈为21.22±3.55 mm。
