Colony formation is crucial for the development of Microcystis blooms, which pose a significant ecological challenge on a global scale. Previous studies have demonstrated that bound extracellular polymeric substances (EPS) play a vital role...
From laboratory to field: Temperature rise triggers increased release and toxicity of microcystins in Microcystis aeruginosa [0.03%]
从实验室到实地：温度上升促进水华鱼腥藻中微囊素的释放和毒性增强
Shihao Wang,Yurong Gu,Weilu Li et al.
Shihao Wang et al.
Temperature rise increases the risk of microcystins (MCs) in aquatic ecosystems by affecting toxin-producing cyanobacteria, but strain-specific responses remain unclear. This study investigated the growth, MCs production and release, isomer...

Heterocystous cyanobacteria are increasingly forming surface blooms in freshwater ecosystems, with massive proliferation events influenced by multiple environmental factors-among which turbulence has emerged as a pivotal driver. This study ...
Characterizing seasonal persistence of low levels of Pseudo-nitzschia australis in the Gulf of Maine with environmental DNA [0.03%]
基于环境DNA揭示新英格兰湾中Pseudo-nitzschia australis低密度高季节性的分布特征
Sydney M Greenlee,Robin S Sleith,Damian C Brady et al.
Sydney M Greenlee et al.
The potent neurotoxin domoic acid is produced by some species of diatoms in the genus Pseudo-nitzschia, which can lead to amnesic shellfish poisoning (ASP) events in marine food webs. Of the toxin-producing Pseudo-nitzschia, P. australis ha...
