在海洋浮游植物的个别物种特异性检测碱性磷酸酶活性
摘要
We evaluated the suitability of ELF-based assay (ELF: Enzyme-Labeled Fluorescence, Molecular Probes) as a tool for specific-detection of alkaline phosphatase (AP) activity in individual species of marine phytoplankton. Among 4 species of marine phytoplankton tested in the present culture experiments, the ELF-labeled cells of Karenia mikimotoi (Dinophyceae) and Skeletonema costatum (Bacillariophyceae) were simultaneously found with AP activity that was determined by using 4-methylumbelliferyl phosphate under the phosphorus-starved state but not found under the phosphorus-replete state. There were significant positive correlations between the percentage of ELF-labeled cells and AP activity of K. mikimotoi and of S. costatum. In contrast for Chattonella antiqua and Heterosigma akashiwo (Raphidophyceae) which do not produce AP, no ELF-labeled cells were found even under the phosphorus-starved state. Thus, ELF-based assay is considered to be useful for specific-detection of AP activity.

我们评估了基于ELF的测定法的适用性(ELF:酶标记的荧光,分子探针)作为用于特定检测海洋浮游植物的个别物种碱性磷酸酶(AP)活性的工具。其中4种海洋浮游植物在目前的培养实验测试了,米氏凯伦藻(甲藻纲)和中肋骨条藻(硅藻)的ELF标记的细胞同时被使用在磷饥饿4-甲基磷酸酯确定AP活动中状态,但磷充满的状态下,没有找到。有ELF标记细胞的米氏凯伦藻的比例和AP活性之间的中肋骨条藻和显著的正相关关系。与此相反的卡盾藻蝇和赤潮异弯藻(Raphidophyceae)不产生AP,没有发现ELF标记的细胞甚至是磷饥饿状态下。因此,ELF为基础的检测被认为是对于特定检测AP活性是有用的。
