Cyanotoxins: New health risk factor in Serbia [PDF]

Archive 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

Toxins, 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

Toxins, 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 ...

Microcystin Production in the Tripartite Cyanolichen Peltigera leucophlebia

Molecular Plant-Microbe Interactions, 2009
We show that the cyanobacterial symbionts of a tripartite cyanolichen can produce hepatotoxic microcystins in situ. Microcystins were detected with high-performance liquid chromatography mass spectrometry both from cephalodia of the tripartite ...

Release and removal of intracellular and extracellular microcystins (RR, LR) using nano-Fe3O4 particles as a coagulant aid for polyaluminum chloride

Water-Energy Nexus
The outbreak of algal blooms caused by cyanobacteria has led to a significant concern regarding water safety due to the release of microcystins. This study aimed to investigate the release and removal of microcystins (RR, LR) using coagulant polyaluminum

The Importance of Lake Sediments as a Pathway for Microcystin Dynamics in Shallow Eutrophic Lakes

Toxins, 2015
Microcystins are toxins produced by cyanobacteria. They occur in aquatic systems across the world and their occurrence is expected to increase in frequency and magnitude. As microcystins are hazardous to humans and animals, it is essential to understand

Structural Characterization of New Microcystins Containing Tryptophan and Oxidized Tryptophan Residues

Marine Drugs, 2013
Microcystins are cyclic peptides produced by cyanobacteria, which can be harmful to humans and animals when ingested. Eight of the (more than) 90 microcystin variants presently characterized, contain the amino acid tryptophan.

Toxic mechanisms of microcystins in mammals [PDF]

Toxicology Research, 2017
This review discusses mechanisms of toxicity, particularly those observed in liver tissue, mediated by microcystins (MCs) produced by cyanobacteria.

Cyanobacterial Toxic and Bioactive Peptides in Freshwater Bodies of Greece: Concentrations, Occurrence Patterns, and Implications for Human Health

Marine Drugs, 2015
Cyanobacterial harmful algal blooms represent one of the most conspicuous waterborne microbial hazards in aquatic environments mostly due to the production of toxic secondary metabolites, mainly microcystins (MCs). Other bioactive peptides are frequently

Cyanobacterial Abundance and Microcystin Profiles in Two Southern British Lakes: The Importance of Abiotic and Biotic Interactions

Toxins, 2020
Freshwater cyanobacteria blooms represent a risk to ecological and human health through induction of anoxia and release of potent toxins; both conditions require water management to mitigate risks.
