Microcystis aeruginosa is a well-known Cyanobacterium responsible for the formation of toxic water blooms around the world. Shallow, warm, and eutrophic reservoirs provide the most favourable conditions for M. aeruginosa development. Numerous studies have been devoted to this species, but there still is a necessity to develop additional approaches for the monitoring of cyanobacteria in reservoirs. In this study, M. aeruginosa in the water column of a hypereutrophic Siberian reservoir was investigated by fluorescence, light, and electron microscopy as well as genetic analysis using a mcyE marker. Here, we demonstrate the genetic diversity and features of the fluorescence spectra for different ecotypes of this species. We suggest that a fluorescence approach can be used to identify M. aeruginosa in a natural environment in order to increase the effectiveness of ecological monitoring and water quality evaluation.
铜绿微囊藻是一种广为人知的蓝藻，它会在世界各地导致有毒水华的形成。浅而温暖且富营养化的水库为铜绿微囊藻的生长提供了最有利的条件。已经有许多研究致力于研究该物种，但仍需要开发额外的方法来监测水库中的蓝藻。在这项研究中，通过荧光、光学和电子显微镜以及使用 mcyE 标记的遗传分析，研究了西伯利亚富营养化水库水柱中的铜绿微囊藻。在这里，我们展示了该物种不同生态型的遗传多样性和荧光光谱特征。我们认为荧光方法可用于识别自然环境中的铜绿微囊藻，以提高生态监测和水质评估的效果。
