摘　　要：近年来,随着全球气候变暖和水体富营养化加剧,国内外多处水源地出现了以有害丝状蓝藻伪鱼腥藻(Pseudanabaena sp.)为主要优势种的蓝藻水华现象。伪鱼腥藻在生长过程中会产生大量异嗅物质2-甲基异莰醇(2-methylisoborneol,简称2-MIB),严重影响水体环境和供水水质。本文对伪鱼腥藻的分类地位、形态特征、全球分布、生长生理特性、产生的异嗅物质以及在饮用水中的去除等研究进行了综述;明确了伪鱼腥藻对温度、pH和磷浓度均有较宽适应范围的特点,这可能是其全球分布广泛并在许多水体中成为优势种的原因;介绍了伪鱼腥藻中2-MIB的合成途径,指出现有研究中伪鱼腥藻生长与产2-MIB的关系存在的争议;通过对比水处理工艺对伪鱼腥藻和2-MIB的去除效果,指出现有处理技术的优点和不足。在此基础上,从理论研究和技术研发两个方面进行展望,以期为进一步研究伪鱼腥藻和2-MIB的有效控制和去除提供参考。Due to global warming and eutrophication,Pseudanabaena sp.has become the main dominant species of cyanobacterial blooms in many water bodies around the world.During the growth of Pseudanabaena sp.,a large amount of 2-methylisoborneol(2-MIB) is produced,which severely degrades the aquatic environment and threatens the safety of drinking water.Here,we provide an up-to-date review of Pseudanabaena sp.,including its taxonomic rank,morphological features,global distribution,growth and physiological characteristics,as well as the production and removal of its metabolite 2-MIB.Pseudanabaena sp.could adapt to a wide range of temperature,pH and phosphorus concentration,which may explain its wide distribution in the world and its dominant status in many water bodies.In addition,we introduced the synthesis of 2-MIB in Pseudanabaena sp.and pointed out the controversy on the relationship between the growth of Pseudanabaena sp.and its production of 2-MIB.We also compared the removal efficiency of Pseudanabaena sp.and 2-MIB resulted from different drinking water treatments,and summarized the advantages and disadvantages of current technologies.Based on the current state of Pseudanabaena sp.research,we proposed the potential advancement of basic science research and technical development in this field.This review provides reference for future studies on the effective control and removal of Pseudanabaena sp.and 2-MIB.
