摘要
以蛋壳粉为原料通过超声波还原法与AgNO_3、NaBH_4作用,制备蛋壳粉纳米银。通过扫描电镜观察蛋壳粉纳米银的形貌及被其处理过的菌的形貌变化,并通过微生物方法对其抑菌性进行研究。结果表明,蛋壳粉纳米银对大肠杆菌、金黄色葡萄球菌、枯草芽孢杆菌、白色念珠菌4种菌均有较好的抑菌效果,最低抑菌浓度(MIC)分别为1. 5,3. 0,3. 0,6. 0 mg/L,最低杀菌浓度(MBC)值分别为6,12,12,24 mg/L。
Eggshell-powder as reactant react with AgNO3 and NaBH4 through ultrasonic reduction method to prepare the eggshell-powder nanosilver. The eggshell-powder nanosilver morphology and morphology changes of treated bacteria were characterized by using Scanning Electron Microscope（SEM）. And its antibacterial properties were characterized by the microorganism meathods. The results showed that silver nanoparticles of eggshell powder had strong bactericidal effect on Escherichia coli,Staphylococcus aureus,Bacillus subtilis and Candida albicans etc. And the minimum inhibitory concentration（MIC） of this four bacterias were1. 5,3. 0,3. 0,6. 0 mg/L and minimum bactericidal concentration（MBC）were 6,12,12,24 mg/L.
