| 摘 要： | 微生物以其独特的生理生化特性,在市政污水处理中承担着去除有机物和脱氮除磷的重要作用,然而纳米金属及其氧化物的广泛应用提高了纳米材料进入污水处理厂的可能性,致使污水处理中的微生物暴露在风险环境中。文中从微生物聚集体存在形式角度出发,概述了纳米材料对微生物特性的影响,揭示了微生物在不利条件下的应对机制,为从群体感应角度深入探究微生物应对纳米材料等胁迫作用提供重要理论依据,并对曾处于胁迫下的微生物功能修复的可能性提出展望。

| Abstract: | Microorganisms play an important role in organic removal and nitrogen and phosphorus removal in wastewater treatment process due to their unique physiological and biochemical characteristics. However, wide application of nano-metals and nano-oxides has increased the possibility of nanoparticles entering wastewater treatment plants, resulting in microbial exposed in risk. From the point of the form of microbial aggregates, the paper summarizes the influence of nanoparticles on microbial characteristics, reveals response mechanism of microorganisms under adverse conditions, provides an important theoretical basis for further study of microbial response to stresses such as nanoparticles from the perspective of quorum sensing, and prospects for the possibility of microbial functional recovery which used to be exposed in risk. |
