摘要
进行了La(Ⅲ)抑菌实验,采用比浊法、平板计数法、滤纸片法对大肠杆菌(Escherichia coli)、金黄色葡萄球菌(Staphulococcus aureus)和枯草芽孢杆菌(Bacillus subtilis)进行了测定. 结果表明:所用抑菌物对供试菌均有不同程度的抑制作用,当La(Ⅲ)的浓度为1.0×10-6~1.0×10-4mol/L时抑制作用最明显,且随着La(Ⅲ)离子浓度增大,抑菌作用趋势增强.
The bacteriostat of La (Ⅲ) is studied against Escherichia col, Staphulococcus aureus,and Bacillus subtilis by spectrophotometer,plate count and filter method. Distinct inhibiting effect was observed on tested bacteria when the concentration of La( Ⅲ ) is in 1.0×10^-6-1.0×10^-4mol/L while inhibiting effect increases from 1.0× 10^-6to 1.0×10^-4mol/L.
