用竹醋 ４ 种分馏物 ＢＶ－ Ｆ，ＢＶ－ Ｍ ，ＢＶ－ Ｕ，ＢＶ－ Ｓ分别对大肠杆菌、金黄色葡萄球菌、桔青霉菌和黑曲霉菌进行抑菌试验．结果表明，竹醋４ 种分馏物对 ４ 种菌都有较强的拮抗作用．ＢＶ－ Ｆ原液和体积分数 １／２～１／１６ 的混合液可杀死培养基表面的全部桔青霉菌，ＢＶ－ Ｆ 原液的最大抑菌圈直径达 ６１ ｍ ｍ ．ＢＶ－ Ｓ对金黄色葡萄球菌抑菌的最小体积分数为 １／２５６．ＢＶ－ Ｓ 对桔青霉菌抑菌的最小体积分数为 １／１２８
The antibacterial activities of Escherichia coli, Staphylococcus aureus, Penicillium citrinum and Aspergillus niger were tested by BV-F, BV-M, BV-U and BV-S. The results showed that four kinds of bamboo vinegar distillate on the four kinds of bacteria have a strong antagonistic effect. BV-F stock solution and the volume fraction of 1/2 ~ 1/16 mixture can kill all Penicillium citrinum on the surface of the culture medium, the maximum inhibitory zone diameter of BV-F stock solution is 61 m. BV-S Staphylococcus aureus antibacterial minimum volume fraction of 1/256. The minimum volume fraction of BV-S to Penicillium citrinum is 1/128
