Statistical Inferences Applying Non-Parametric Data on Cyanobacterial Investigations: Contributions to Water Quality and New Trends under Global Changes on Portuguese Freshwater Ecosystems

Toxins, 2022
Cyanobacteria are a bloom-forming ancient group of photosynthetic prokaryotes. A rise in temperature is a major contributor to its massive proliferation, namely on freshwater ecosystems, with social and economic impacts. Thus, reliable and cost-effective

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

Marine 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

Cylindrospermopsin: occurrence, methods of detection and toxicology [PDF]

Journal of Applied Microbiology, 2012
Cyanobacteria are aquatic micro-organisms that pose a great threat to aquatic ecosystems by the production of dense blooms, but most importantly by the production of secondary metabolites, namely the cyanotoxins. One of these is cylindrospermopsin (CYN), a hepatotoxic polyketide-derived alkaloid with well-known associated cases of animal mortalities ...

Detoxification of Cylindrospermopsin by Pyrite in Water [PDF]

Catalysts, 2019
Cylindrospermopsin (CYN) is a cyanobacterial toxin released from eutrophic water. It persistently remains in the environment because its degradation under solar light is extremely low. In this study, pyrite, an abundant mineral, was investigated as a catalyst for decomposing and detoxifying CYN in water. A detailed examination of intermediates provided

Multi-Toxin Occurrences in Ten French Water Resource Reservoirs

Toxins, 2018
Cyanobacteria are known to produce a wide array of metabolites, including various classes of toxins. Among these, hepatotoxins (Microcystins), neurotoxins (Anatoxin-A and PSP toxins) or cytotoxins (Cylindrospermopsins) have been subjected to numerous ...

Alternative Isolation Protocol for Desulfo and Zwitterionic Cylindrospermopsin Alkaloids and Comparison of Their Toxicity in HepG2 Cells

Molecules, 2020
The term cylindrospermopsins (CYNs) refers to a structurally related class of cyanobacterial metabolites comprised of a tricyclic guanidine group and a hydroxymethyluracil moiety. Most reports in environmental aquatic samples refer to cylindrospermopsin (

Diversity and distribution of cyanobacterial toxins in the Italian subalpine lacustrine district [PDF]

, 2012
Nine lakes (Garda, Maggiore, Como, Iseo, Lugano, Idro, Pusiano, Ledro and Levico) located in the Italian subalpine lacustrine district have been chosen for a comparative study about the diversity and the distribution of cyanobacterial toxins.

Cyanopeptide Mixtures Induce Variable Synergistic and Antagonistic Effects Across Diverse Human Cell Lines

Environmental Toxicology, Volume 41, Issue 10, Page 807-821, October 2026.
ABSTRACT Cyanobacterial harmful algal blooms (cyanoHABs) threaten human, animal, and ecosystem health and safety through production of toxic secondary metabolites. Microcystis, a cosmopolitan bloom‐forming cyanobacterial genus, is well‐known for producing hepatotoxic microcystins (MCs), but it can produce many other bioactive cyanopeptides, such as ...

Optimizing a long‐term monitoring strategy to track emerging cyanobacterial blooms in a Great Lakes estuary

Journal of Phycology, Volume 62, Issue 4, Page 1264-1296, August 2026.
Abstract Cyanobacterial harmful algal blooms (cHABs) are increasingly frequent and severe globally. Recently, the St. Louis River Estuary (SLRE) has experienced numerous cHABs, but the locations, timing, and environmental conditions associated with them are unknown.
