藻毒素的生物降解研究进展

近年来蓝藻水华污染产生的有毒代谢产物藻毒素对水生生态系统和人类健康构成严重的威胁。生物降解技术尤其是生物滤池由于运行维护费用低并且不产生有毒副产物,已广泛应用于去除藻毒素。然而,水处理过程中可能存在的生物降解多种藻毒素效果的信息少有收集,这在越来越多不同种类的藻毒素能同时在水源地中检测出来的情况下更加重要。综述了目前所有藻毒素生物降解性的相关研究进展,分析了影响藻毒素生物降解的因素,并探讨了目前藻毒素生物降解技术如何在水处理过程中应用优化去除藻毒素效果,为运用生物降解方法控制或去除各种藻毒素提供理论指导。

Research Progress in Biodegradation of Cyanobacterial Toxins

In recent years,toxic metabolites produced by pollution of cyanobacterial blooms pose a serious threat to aquatic ecosystem and human health.Biodegradation technologies especially biological filtration have been widely used to remove algal toxins due to low cost of operation and maintenance with no potentially harmful by-products. However,there is little information gathered with respect to the effectiveness of biological treatment for all kinds of cyanobacterical toxins.It is especially important due to multiple kinds of cyanobacterical toxins been detected sim-ultaneously in water sources.In this paper,the research progress published to date on the biodegradation of cya-nobacterial toxins in water is reviewed,and the factors which have impact on the biodegradation of these toxins are analysed.Moreover,this article also offers insights into how biological treatment options can be applied to get opti-mum effect of removing cyanobacterial toxins,in particular through biological filtration process.This research is aimed at providing a theoretical guidance for the application of biodegradation technologies to remove cyanobacterial toxins.
