摘　　要：[目的]研究碳纳米材料在紫外条件下对微生物细胞的生物学效应。[方法]以pUC19质粒的大肠杆菌(E.coli)为材料,研究多壁纳米碳管、纳米碳粉在不同紫外强度下对微生物存活率的影响。[结果]通过不同时间的紫外照射试验表明,加入纳米碳管可以有效增加存活菌落数目,而加入纳米碳粉也能提高微生物的存活率。[结论]碳纳米材料能够提高微生物在紫外条件下的生存率。[Objective] The aim was to study the biological effect of carbon nano-material on microorganism under ultraviolet radiation.[Method] Using E.coli with plasmid pUC19,the survival rate of microorganism was investigated by different intensity of ultraviolet radiation cultivated with carbon nanotube and cabon nanopowder.[Result] The experimental results showed that the addition of carbon nanotube could increase the number of survival bacteria colony,meanwhile,the survival rates of the microorganism was increased by cultivated with carbon nano-powder.[Conclusion] The carbon nano-material could increase the survival rate of microorganism under ultraviolet radiation.
