摘要
抗生素与抗生素抗性基因(ARGs)污染严重危害人类健康,微藻生物技术在处理抗生素废水过程中表现出良好的效果.文章首先总结了微藻对于不同种类抗生素的去除机理,包括生物吸附、生物累积、生物降解、光生物降解和水解挥发5 种.分析了微藻在去除抗生素过程中的重要影响因素,包括pH、水力停留时间、光照、抗生素的种类与浓度和微藻的种类.并总结了微藻对ARGs的去除机制,包括移动基因元件的去除及活性氧自由基的猝灭.最后,文章指出了微藻处理抗生素废水过程中仍然存在的问题,进一步明确了今后微藻生物技术处理抗生素废水的重点研究方向.
Abstract
Antibiotics and antibiotic resistance genes(ARGs)pollution pose a serious threat to human health,and microalgae biotechnology has shown good results in the treatment of antibiotic wastewater.This paper summarizes the removal mechanism of different kinds of antibiotics by microalgae,including biosorption,bioaccumulation,biodegradation,photodegradation and hydrolysis volatilization.The important factors affecting the removal of antibiotics by microalgae were analyzed,including pH,hydraulic retention time,light,the types and concentrations of antibiotics,and the species of microalgae.And the removal mechanism of ARGs by microalgae was summarized,including removal of mobile gene elements and quenching of reactive oxygen species.Finally,the paper points out the existing problems in the treatment of antibiotic wastewater by microalgae,and further clarifies the key research directions for the treatment of antibiotic wastewater by microalgae biotechnology in the future.
