化感物质抑制藻类过度繁殖的机理及效能研究进展

Research Progress of Mechanism and Effect of Allelochemicals on Inhibition of Algal Overgrowth

近年来,蓝藻水华的频发及其藻毒素次生等代谢产物的污染不断危害着水生生态环境和社会安全,植物分泌的化感物质被证实对水华藻种具有一定控制作用,能通过拮抗作用抑制藻类的过度繁殖。文中针对化感物质对水华藻种的抑制作用,在总结化感物质抑藻研究现状的基础上,重点阐明化感物质的典型种类以及其对水华藻种的作用机理及效能,同时结合实际水体中藻类控制需求,分析了现有化感物质抑藻研究中存在的不足,并对后续研究趋势进行了展望。

In recent years,the frequent occurrence of cyanobacteria blooms and the pollution of secondary metabolites such as cyanobacteria toxins have been constantly endangering the aquatic ecological environment and social safety.Allelochemicals secreted by plants has been proved to have a certain control effect on cyanobacteria blooms and can inhibit the overpopulation of algae through antagonistic effect.This paper focuses on the inhibitory effect of allelochemicals on species that can cause algae blooming,emphasized the typical types of allelochemicals and their mechanisms and effectson aquamarine species on the basis of summarizing the research status of allelochemicals inhibiting algae.Meanwhile analyzed the allelochemicals in addition to algae of the defects in the existing research combined with the actual algae control demand,and the future research trends were prospected.
