作者 Katharine Davis 何晓窦 《当代外语研究》 2005年第1期11-12,共2页
不久前,美国佛州大学科研人员发明了一种新的通过纳米粒子检测有害细菌的试验方法。与寻常方法相比,新的纳米粒子检测法用时更短,花费更低,并且能一次检测出不同类型的细菌。

Wastewater is a breeding ground for many pathogens,which may pose a threat to human health through various water transmission pathways.Therefore,a simple and effective method is urgently required to monitor and treat wastewater.As bacterial viruses,bacteriophages(phages)are the most widely distributed and abundant organisms in the biosphere.Owing to their capacity to specifically infect bacterial hosts,they have recently been used as novel tools in water pollution control.The purpose of this review is to summarize and evaluate the roles of phages in monitoring pathogens,tracking pollution sources,treating pathogenic bacteria,infecting bloom-forming cyanobacteria,and controlling bulking sludge and biofilm pollution in wastewater treatment systems.We also discuss the limitations of phage usage in water pollution control,including phage-mediated horizontal gene transfer,the evolution of bacterial resistance,and phage concentration decrease.This review provides an integrated outlook on the use of phages in water pollution control. 展开更多
