以大肠杆菌和鼠伤寒沙门氏菌为试验菌株,比较研究了铜离子-氧化锌/十六烷基铵基吡啶-蒙脱石复合材料(Cu2+-ZnO/CP-MMT)的抗菌活性.结果表明,Cu2+-ZnO/CP-MM工具有较高的抗菌活性,对大肠杆菌的最小抑菌质量浓度和杀菌质量浓度分别为800μg/mL和160μg/mL,对鼠伤寒沙门氏菌的最小抑菌质量浓度和杀菌质量浓度分别为40μg/mL和160μg/mL.Cu2+-ZnO/CP-MMT对所试菌均产生抗菌剂后效应和持续押菌效应.320μg/mL的Cu2+-ZnO/CP-MMT能在12h内杀灭大肠杆菌和鼠伤寒沙门氏菌,而640μg/mL的Cu2+-ZnO/CP-MMT能在6h内杀灭大肠杆菌,4h内杀灭鼠伤寒沙门氏菌.
