Microcystins in planktonic and benthic food web components from Greenlandic lakes

open access: yesEcosphere, 2021
There is increasing global concern regarding the social, economic, human health, and environmental health implications of cyanotoxins. However, much of what we know about cyanotoxins comes from studies of temperate or tropical systems with conspicuous ...

Cyanotoxins: A Poison that Frees Phosphate [PDF]

open access: yesCurrent Biology, 2010
Autotrophic organisms obtain phosphorus from the environment by secreting alkaline phosphatases that act on esters, resulting in inorganic phosphate that is then taken up. New work shows that the cyanobacterium Aphanizomenon ovalisporum obtains inorganic phosphate by secreting the cyanotoxin cylindrospermopsin, which induces alkaline phosphatase in ...

Cyanotoxins at low doses induce apoptosis and inflammatory effects in murine brain cells: Potential implications for neurodegenerative diseases

open access: yesToxicology Reports, 2016
Cyanotoxins have been shown to be highly toxic for mammalian cells, including brain cells. However, little is known about their effect on inflammatory pathways.

Cyanotoxins: A dermatological problem

open access: yesArchive of Oncology, 2011
Cyanobacteria (blue-green algae), that are common inhabitants of water and terrestrial environments throughout the world, produce a broad spectrum of secondary metabolites - biologically active products that could be toxic (cyano?toxins). Scientific literature data unequivocally showed adverse effects of cyanotoxins on animal and human ...

Degradation of cyanotoxins (microcystin) in drinking water using photoelectrooxidation

open access: yesBrazilian Journal of Biology
The discharge of sewage and industrial effluents containing high concentrations of pollutants in water bodies increases eutrophication. Cyanobacteria, some of the organisms whose growth is promoted by high nutrient concentrations, are resistant and ...

Passive environmental DNA sampling: A review of current practices, limitations and future directions for biodiversity monitoring

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 5, Page 1535-1555, May 2026.
Abstract Passive environmental DNA (eDNA) sampling is rapidly emerging as a powerful alternative to active sampling methods (e.g. direct water sampling), with a rapidly growing diversity of tested approaches but little methodological convergence.

Ecological and molecular investigations of cyanotoxin production [PDF]

open access: yesFEMS Microbiology Ecology, 2001
Cyanobacteria, broadly classified as oxygenic phototrophs containing chlorophyll- a and accessory pigments, are among the oldest life forms on earth. They may be unicellular, colonial or filamentous, with cell sizes varying from less than 2 μm to 40 μm in diameter. They may live as symbionts with plants and fungi, in the benthos or in the water column.

Cyanobacterial Cyclic Peptides Containing cis‐Pro Conformation

open access: yesChemistry – A European Journal, Volume 32, Issue 13, 1 April 2026.
Cyanobacterial cyclic natural products are ribosomal or nonribosomal peptides, typically containing one or more proline residues. However, the presence and population of the cis‐Pro conformation are not always explicitly stated in the literature. The two proline isomers can affect protein function and interactions.

Toxicity at the Edge of Life: A Review on Cyanobacterial Toxins from Extreme Environments

open access: yesMarine Drugs, 2017
Cyanotoxins are secondary metabolites produced by cyanobacteria, of varied chemical nature and toxic effects. Although cyanobacteria thrive in all kinds of ecosystems on Earth even under very harsh conditions, current knowledge on cyanotoxin distribution

The Occurrence of Potential Harmful Cyanobacteria and Cyanotoxins in the Obrzyca River (Poland), a Source of Drinking Water

open access: yesToxins, 2020
Harmful cyanobacteria and their cyanotoxins may contaminate drinking water resources and their effective control remains challenging. The present study reports on cyanobacterial blooms and associated cyanotoxins in the Obrzyca River, a source of drinking
