新型纳米无机抗菌剂TiO_2和ZnO的广谱抗菌性研究

Study on the antimicrobial activities of nanometer inorganic antibacterial agents TiO_2 and ZnO

选择了革兰氏阴性细菌、革兰氏阳性细菌、芽孢杆菌、酵母菌和霉菌的代表菌株,采用三角瓶振荡法及纸片扩散法,对2种新型纳米无机抗菌剂:纳米TiO2和纳米ZnO进行了广谱抗菌性研究,并通过与日本的纳米无机抗菌剂及有机抗菌剂进行比较,结果表明2种新型纳米抗菌剂不仅对所有代表菌株表现出很好的广谱抗菌性能,而且其抑菌能力强于日本无机抗菌剂和有机抗菌剂;在此基础上对相关抗菌剂的抗菌机理进行了分析讨论.

The qualitative antibacterial activities of two new inorganic antibacterial agents TiO2 and ZnO were studied to the typical Gram-negative bacteria,Gram-positive bacteria,bacillus,microzyme and mould by the experiments of vibrating flask and the disk diffusion.The experimental results show that the two new nanometer inorganic antibacterial agents have broad-spectrum antibacterial activities and the antibacterial effect is much better than that of organic antibacterial agents and the inorganic antibacterial a...
