A Review of Common Cyanotoxins and Their Effects on Fish

open access: yesToxics, 2023
Global warming and human-induced eutrophication drive the occurrence of various cyanotoxins in aquatic environments. These metabolites reveal diversified mechanisms of action, encompassing cyto-, neuro-, hepato-, nephro-, and neurotoxicity, and pose a ...

High ecological and human health risks from microcystins in vegetable fields in southern China

open access: yesEnvironment International, 2019
Frequent cyanobacterial blooms in the eutrophic waters produce a variety of toxins such as the monocyclic heptapeptide microcystins, greatly harming aquatic ecosystems and human health.

Microcystin-Detoxifying Recombinant Saccharomyces cerevisiae Expressing the mlrA Gene from Sphingosinicella microcystinivorans B9

open access: yesMicroorganisms, 2023
Contamination of water by microcystins is a global problem. These potent hepatotoxins demand constant monitoring and control methods in potable water. Promising approaches to reduce contamination risks have focused on natural microcystin biodegradation ...

Chirality in microcystins [PDF]

open access: yesJournal of the American Society for Mass Spectrometry, 1994
A new method has been developed to identify the isomers of amino acids by derivatization of the corresponding standards with 1-fluoro-2,4-dinitrophenyl-5-L-alanine amide (Marfey's reagent or FDAA) and analysis of the diastereomeric derivatives by a liquid chromatography-thermospray mass spectrometry technique.

An efficient and affordable laboratory method to produce and sustain high concentrations of microcystins by Microcystis aeruginosa

open access: yesMethodsX, 2019
Microcystis aeruginosa is a cosmopolitan cyanobacteria that continues to jeopardize freshwater ecosystem services by releasing the hepatotoxin microcystin, which can, in some cases, cause death to aquatic fauna and even humans.

Differential effects of nitrate and ammonium on the growth of algae and microcystin production by nitrogen-fixing Nostoc sp. and non-nitrogen-fixing Microcystis aeruginosa

open access: yesWater Science and Technology, 2023
Cyanotoxins produced by cyanobacteria are a significant threat to human health. However, their responses to nitrogen (N) supplies could differ between N-fixing and non-N-fixing species, which has been poorly understood.

Cyanotoxins: New health risk factor in Serbia [PDF]

open access: yesArchive of Oncology, 2008
Cyanobacteria are responsible for poisoning numerous cases of livestock and other animals, but sometimes they induce serious problems in humans. Mass occurrence and blooms of cyanobacteria were studied in rivers, canals, lakes, and accu­mulations that ...

Are We Underestimating Benthic Cyanotoxins? Extensive Sampling Results from Spain

open access: yesToxins, 2017
Microcystins (MCs) are potent hepatotoxins, and their presence in water bodies poses a threat to wildlife and human populations. Most of the available information refers to plankton, and much less is known about microcystins in other habitats. To broaden

Microcystin Prevalence throughout Lentic Waterbodies in Coastal Southern California

open access: yesToxins, 2017
Toxin producing cyanobacterial blooms have increased globally in recent decades in both frequency and intensity. Despite the recognition of this growing risk, the extent and magnitude of cyanobacterial blooms and cyanotoxin prevalence is poorly ...
