Antimycobacterial and cytotoxicity activity of microcystins [PDF]
The present work aimed to evaluate the antimycobacterial activity and cytotoxicity of Microcystis aeruginosa toxins, the MC-LR variant and purified extract of [D-Leu(1)] microcystin-LR.The antimicrobial activity of M. aeruginosa extract and microcystin was evaluated by resazurin microtiter assay against Mycobacterium tuberculosis, M.

This review elucidates the molecular mechanisms of algicidal bacteria, highlighting critical behaviours like chemotaxis, quorum sensing and extracellular vesicle release. It details how these actions disrupt algal cellular integrity, photosynthesis and calcium homeostasis, providing a theoretical foundation for controlling harmful algal blooms ...

Gastrointestinal toxicity induced by microcystins
Microcystins (MCs) are produced by certain bloom-forming cyanobacteria that can induce toxicity in various organs, including renal toxicity, reproductive toxicity, cardiotoxicity, and immunosuppressive effects. It has been a significant global environmental issue due to its harm to the aquatic environment and human health.

ABSTRACT Planktothrix rubescens is a toxin‐producing filamentous cyanobacterium commonly found in temperate stratified lakes. Planktothrix rubescens regulates its buoyancy through intracellular gas vesicles and typically accumulates in the metalimnion during summer stratification, forming substantial biomass within a thin layer.

Investigation of Microcystin Processing, Production and Export by Microcystis sp.
During this study, the effect of different processing methods on the microcystin quota (microcystins per cell) was investigated. Microcystins from two Microcystis strains and one Planktothrix strain were quantified using liquid chromatography-mass ...
