银杏-橙花叔醇复方对东海原甲藻的协同抑藻效应及机理研究
Synergistic algicidal effects and mechanisms of the Ginkgo biloba-nerolidol compound on Prorocentrum donghaiense
摘要
Abstract
This study constructed a compound formulation using 1.0 mg·L-1 nerolidol and 1.0 g·L-1 Ginkgo biloba leaf extract,measuring cell density,chlorophyll fluorescence parameters,and cell membrane permeability of Prorocentrum donghaiense to investigate the combined algal inhibition mechanism.The results showed that the compound formulation exerted a synergistic inhibitory effect on the growth of Prorocentrum donghaiense,with a 96 h inhibition rate of 74.75%,which was higher than that of single component.The compound not only more strongly reduced algal cell motility but also induced a sharp and persistent decrease in the actual photochemical quantum yield(Fq'/Fm'),light utilization efficiency(α),and maximum relative electron transport rate(rETRmax).Furthermore,the compound formulation further exacerbated the damage to cell membrane permeability.Therefore,the compound formulation has shown synergistic effects in inhibiting algal photosynthesis and damaging cell membranes,and has the potential to be applied as eco-friendly red tide inhibitors.关键词
