摘要：

采用琼脂稀释法测定了几种稀土铈羧酸配合物对大肠杆菌、金黄色葡萄球菌、枯草芽孢杆菌的抑菌活性，得到了它们抑制细菌生长的最小浓度和最小杀菌浓度。结果表明几种稀土铈的羧酸配合物对几种受试菌均有较强的抑制作用，配合物比相应的二配位体具有更高的抑菌活性，而小于相应的单配体羧酸。

关键词: 铈, 羧酸配合物, 抑菌性能, 最小抑菌浓度

Abstract:

We employ agar dilution method to determine the bacteriostasis activity of a carboxylic ligand and its cerium complexes to Escherichia aureus, Staplylococcus aureus and Bacillus subtilis. We also obtain their minimal inhibitory concentration (MIC). Results show that carboxylic acid and its cerium complexes have stronger bacteriostasis activity the bacteriostasis activity of its cerium complexes is higher than that of the dual ligand and lower than that of the unitary ligand.

Key words: cerium, carboxylic acid complexes, bacteriostasis performance, mininal inhibitory concentration
