Cylindrospermopsin (CYN) is a toxic secondary metabolite produced by several freshwater species of cyanobacteria. Its high chemical stability and wide biological activity pose a series of threats for human and animal morbidity and mortality. The biggest risk of CYN exposure for human organism comes from the consumption of contaminated water, fish or seafood. Very important for effective monitoring of the occurrence of CYN in aquatic environment is accurate identification of cyanobacteria species, that are potentially able to synthesize CYN. In this review we collect data about the discovery of CYN production in cyanobacteria and present the morphological changes between all its producers. Additionally we set together the results describing the catalytic decomposition of CYN.

Cylindrospermopsin（CYN）是由几种淡水蓝藻产生的有毒次生代谢产物。它的高化学稳定性和广泛的生物活性对人类和动物的发病率和死亡率构成了一系列威胁。人体接触CYN的最大风险来自食用被污染的水，鱼或海鲜。对于有效监测水生环境中CYN的发生非常重要的是准确识别可能合成CYN的蓝细菌物种。在这篇综述中，我们收集了有关在蓝细菌中发现CYN的发现的数据，并介绍了其所有生产者之间的形态变化。另外，我们将描述CYN催化分解的结果放在一起。
