摘　　要：生物模板仿生合成的介孔磷酸锆通过表征测试证明有良好的性能。以革兰氏阳性菌(G+)、革兰氏阴性菌(G-)和酵母属真菌等10种微生物作为供试菌,抑菌圈试验(定性)和细胞总数测定实验(定量)作为实验方法研究了介孔磷酸锆的抗菌性,并探讨影响其抗菌性的因素和抗菌机理。实验结果显示,介孔磷酸锆对其中的8种菌具有明显的抑菌效果,但对各种菌的抗菌能力表现差异性。说明介孔磷酸锆具有较好的广谱抗菌性,将有广阔的应用前景。Mesoporous zirconium phosphate with biomimetic synthesis of the biological tempfate demonstrated good performance by means of characterization tests. Ten species of microorganisms, including Gram-positive bacteria （G＋ ）, Gram-negative bacteria （G-） and yeast fungi, as the test bacteria. The zone of inhibition test （qualitative） and cell number determination experiments （quantitative） were used experimental methods to investigate the antimicrobial properties of new mesoporous zirconium phosphate, and then the factors that affected its antimicrobial and antibacterial mechanisms were ex- plored. The results showed that mesoporous zirconium phosphate had significant inhibitory effect on the eight of ten kinds of bacteria, but its antibacterial ability to various bacteria represented different. The study stated that mesoporous zirconium phosphate had good broad-spectrum antimicrobial properties,which will have broad application prospects.
