摘要
为了确定不同稀土硝酸盐对金黄色葡萄球菌的抑制作用,选用了8种稀土硝酸盐,进行了轻稀土硝酸盐和重稀土硝酸盐的杀菌效果对比实验.并从中选出硝酸铈作为代表试剂在不同pH、浓度梯度、温度下对金黄色葡萄球菌的抑菌效果进行了实验研究,探讨了其杀菌机理.实验结果表明:轻稀土硝酸盐的抑菌效果强于重稀土;在弱酸,40℃的环境中低浓度的稀土硝酸盐的杀菌效果较好.
To determine the different Lanthanide nitrates for golden colour grape coccus test and have chosen the 8 kinds of Lanthanide nitrates, is bacterium effect light Lanthanide nitrates and the again Lanthanide nitrates kill contrast experiment. And since being chosen Ce （ NO3 ）3 is representative reagent in different pH value, density gradient, under temperature for golden colour grape coccus restrain bacterium effect test research, have discussed its reason of sterilization machine. Experiment result shows： Lanthanide nitrates restrain bacterium effect is more strong than again rare earth ; In weak acid 40 ℃ Lanthanide nitrates of low density in environment kill bacterium effect better.
