酚酸类化感物质抑藻作用的研究进展

阐述了酚酸类化感物质的分离与鉴定方法,探讨了酚酸对藻类的抑制作用机理及其藻类的响应。并对酚酸类化感物质用于工业水处理灭藻剂的前景进行了展望。酚酸对藻类的抑制作用机理包括对藻类细胞膜的破坏,对藻类多种酶活性与功能影响,对藻类光合作用与呼吸作用影响及对藻类基因表达的影响等方面。藻类对酚酸的累积与代谢作用使酚酸类化感物质残留较少,这使其开发为生态安全型灭藻剂成为可能。同时提出今后尚需从酚酸类化感物质的水环境行为与特性、生态安全性及抑藻特异性等方面做进一步深入研究。

RESEARCH PROGRESS ON THE INHIBITORY EFFECTS OF PHENOLIC ACID ALLELOCHEMICALS ON ALGAE

This paper reviewed the methods of isolation and identification of phenolic acid compounds,their inhibition mechanism on algae,and the response of algae to phenolic acids.The prospects of phenolic acids applied as the algicide of industrial water treatment were also discussed.The inhibition mechanisms of phenolic acids on algae included the damage of cell membrane,the impact on multi-enzyme activity and function,photosynthesis,respiration,gene expression,etc.The accumulation and metabolization of algae on phenolic acids made less residue,which made it possible to become a eco-friendly algicide.Meanwhile,it suggested that it was necessary to keep on studying deeply the characters and actions,ecological safety and specificity of phenolic acids in aquatic environment.
