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

Water 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.

Potential endocrine disrupting activity of cyanobacteria: Possible roles for microcystins

, 2020
This thesis investigated the connection between two major global concerns: the infamous cyanobacteria (“blue-green algae”), and the endocrine disruptors, compounds able to interfere with the hormonal system.

Neurotoxicity induced by microcystins and cylindrospermopsin: A review.

Science of the Total Environment, 2019
Microcystins (MCs) and cylindrospermopsin (CYN) are among the most frequent toxins produced by cyanobacteria. These toxic secondary metabolites are classified as hepatotoxins and cytotoxin, respectively.

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
