Sensitised decomposition of microcystin-LR using UV radiation

Journal of Photochemistry and Photobiology B: Biology, 2004
UV radiation was applied to degrade cyanobacterial hepatotoxin, microcystin-LR in the presence of phycocyanin as a model natural sensitiser. The concentrations of both the toxin and the pigment used in the experiments were higher by several orders of magnitude than found in the environment. The photoreaction parameters were optimised.

Impacts of microcystin, a cyanobacterial toxin, on laboratory rodents in vivo

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008
Cyanobacterial water blooms became a global problem/issue because beside a dramatic deterioration of water quality parameters they also produce cyanobacterial toxins being harmful for animals and humans.

Cyanotoxins: methods and approaches for their analysis and detection [PDF]

, 2017
Cyanotoxins are secondary metabolites produced by cyanobacteria, a group of photosynthetic prokaryota especially found in freshwater. In favourable conditions (i.e. high nutrient levels, light intensity, water temperature), cyanobacteria can form blooms,

Aptamer Engineering: Strategies for Discovering Functional Nucleic Acids for Next‐Generation Diagnostics and Biosensing

Advanced Science, Volume 13, Issue 2, 9 January 2026.
The advent of aptamers has highlighted their potential as alternatives to antibodies, overcoming limitations of structural instability and production cost. However, conventional approaches such as SELEX remain slow and labor‐intensive. This review examines recent advances in aptamer engineering, emphasizing in vitro and AI‐driven in silico strategies ...

Noncompetitive Chromogenic Lateral-Flow Immunoassay for Simultaneous Detection of Microcystins and Nodularin

Biosensors, 2019
Cyanobacterial blooms cause local and global health issues by contaminating surface waters. Microcystins and nodularins are cyclic cyanobacterial peptide toxins comprising numerous natural variants.

In situ studies on physiological and biochemical responses of four fishes with different trophic levels to toxic cyanobacterial blooms in a large Chinese lake [PDF]

, 2007
Physiological and biochemical responses of four fishes with different trophic levels to toxic cyanobacterial blooms were studied in a large net cage in Meiliang Bay, a hypereutrophic region of Lake Taihu.

Photocatalytic degradation of microcystin-LR in aqueous solutions

Chemosphere, 2013
In this work, the photocatalytic degradation of aqueous microcystin-LR was studied using TiO(2) and ZnO as photocatalysts. The process was optimised and characterised at the bench scale (200 mL); both semiconductors exhibited a high degradation capacity at reaction times of 1 min (degradation greater than 95%).

Cyanobacteria and Cyanotoxins in Mediterranean Reservoirs: Ecological Variability, Risks and Implications for Water Quality Assessment

Ecohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT The increasing demand for freshwater, in combination with climate change and pollution, compromises the quality and quantity of water resources. These pressures have intensified cyanobacterial blooms, including toxic events that threaten human health and aquatic ecosystems. This study complements the objectives of the Water Framework Directive

Evidence of trophic transfer of microcystins from the gastropod Lymnaea stagnalis to the fish Gasterosteus aculeatus. [PDF]

, 2014
International audienceAccording to our previous results the gastropod Lymnaea stagnalis exposed to MC-producing cyanobacteria accumulates microcystins (MCs) both as free and covalently bound forms in its tissues, therefore representing a potential risk ...
