摘　　要：试验设定了6个TTPC浓度梯度处理组和1个对照组,研究十四烷基三丁基氯化鏻(TTPC)对铜绿微囊藻(FACHB469)生长及生理的影响。结果表明当TTPC浓度超过0.6 mg/L时能有效地抑杀铜绿微囊藻,当TTPC浓度为0.8 mg/L,藻细胞与药剂接触时间96 h,相对抑制率达84.68%,同时铜绿微囊藻的可溶性蛋白质量分数、叶绿素a含量及总糖质量分数与对照组相比均显著下降(p<0.05)。根据以上实验结果,我们结果推测TTPC杀藻机理可能是通过阻碍藻细胞生命活动所必需的蛋白合成,抑制叶绿素a的合成,导致藻细胞生命活动所需糖类等物质含量急剧降低,从而使藻细胞生命过程受到阻塞,最终破坏整个藻细胞。Effects of tributyl tetradecyl phosphonium chloride（TTPC） with six treatments on the growth and physiology of Microcystis aeruginosa were studied by measuring algaecidal activity,soluble protein content,Chlorophyll a content and total sugar content of algal cells.Results showed that TTPC more than 0.6 mg/L could inhibit M.aeruginosa growth efficiently,and the relative inhibitory rate was 84.68% treated by 0.8 mg/L TTPC after 96 h exposure.Soluble protein content,Chlorophyll a content and total sugar content of algal cells of M.aeruginosa have significantly decreased compared to the control group under the influence of 0.8 mg/L TTPC.All the results indicated that the mechanisms of algaecidal activity were that TTPC hindered soluble protein synthesis,decreased total sugar content by inhibiting Chlorophyll a synthesis,which resulted in inhibiting the vital process of algal cells in the end.
