磷对四尾栅藻代谢有机物生成规律的影响

基金项目: 国家自然科学基金项目(41273137,51108030,51378063);北京市自然科学基金项目(8132033);城市水资源与水环境国家重点实验室开放课题(ES201204,QAK201306)

Effects of Phosphorus Concentration on Algal Organic Matters Formation from Scenedesmus quadricauda

  • 摘要: 通过改变培养基中ρ(TP),并结合TOC(总有机碳)分析、考马斯亮蓝法、蒽酮硫酸法和茚三酮法研究不同ρ(TP)对水华中常见绿藻——四尾栅藻的生长规律及其IOMs(胞内有机物)和EOMs(胞外有机物)中TOC、蛋白质、碳水化合物和氨基酸代谢规律的影响. 结果表明,随着ρ(TP)的增加,四尾栅藻生长的指数期变长. ρ(TP)为0.01 mg/L时有利于四尾栅藻EOMs中碳水化合物的形成与积累,ρ(碳水化合物)在指数期达到最大,为89.25 mg/L;ρ(TP)为0.20 mg/L时则有利于四尾栅藻EOMs中氨基酸的形成,并且ρ(氨基酸)在稳定期达到最大,为13.72 mg/L. ρ(TP)为0.01 mg/L时有利于四尾栅藻IOMs中氨基酸的形成,ρ(氨基酸)在指数期达到最大值(21.85 mg/L). 利用EEM(三维荧光)对四尾栅藻的EOMs和IOMs进行表征发现,ρ(TP)的改变会对四尾栅藻IOMs和EOMs中不同物质的峰强产生影响;同时,随着藻细胞的生长,ρ(TP)也会影响四尾栅藻EOMs中的物质组成.
