A 15-min non-competitive homogeneous assay for microcystin and nodularin based on time-resolved Förster resonance energy transfer (TR-FRET) [PDF]

open access: yes, 2022
Simple and rapid methods are required for screening and analysis of water samples to detect cyanobacterial cyclic peptide hepatotoxins: microcystin/nodularin.

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

Investigation of the Occurrence of Cyanotoxins in Lake Karaoun (Lebanon) by Mass Spectrometry, Bioassays and Molecular Methods

open access: yesToxins, 2021
Lake Karaoun is the largest artificial lake in Lebanon and serves multiple purposes. Recently, intensive cyanobacterial blooms have been reported in the lake, raising safety and aesthetic concerns related to the presence of cyanotoxins and cyanobacterial

Effects of Salinity and Temperature on the Growth, Toxin Production, and Akinete Germination of the Cyanobacterium Nodularia spumigena

open access: yesFrontiers in Marine Science, 2019
Harmful blooms of the cyanobacterium Nodularia spumigena occur in several parts of the world, and this species is notorious for its ability to produce cyanotoxins, such as nodularin.

Prediction of present and future spatial occurrence of cyanobacteria and the toxin nodularin in the Baltic Sea [PDF]

open access: yesBiogeosciences
Blooms of filamentous cyanobacteria are recurrent phenomena in the brackish Baltic Sea. These blooms can contain toxin-producing strains. However, predicting and modeling the toxins spatial distribution poses great challenges.

Transfer of nodularin to copepod Eurytemora affinis through the microbial food web [PDF]

open access: yes, 2009
Nodularia spumigena Mertens ex Bornet & Flahault 1886 (Cyanophyceae) frequently forms harmful blooms in the Baltic Sea, and the toxin nodularin has been found in calanoid copepods during the blooms. Although nodularin has been found at higher trophic

Multiple Stressors at the Land-Sea Interface: Cyanotoxins at the Land-Sea Interface in the Southern California Bight

open access: yesToxins, 2017
Blooms of toxic cyanobacteria in freshwater ecosystems have received considerable attention in recent years, but their occurrence and potential importance at the land-sea interface has not been widely recognized.

Nodularin and cylindrospermopsin: a review of their effects on fish [PDF]

open access: yesReviews in Fish Biology and Fisheries, 2014
Nodularin (NOD) and cylindrospermopsin (CYN) are hepatotoxic cyanotoxins that are present in numerous ecosystems where bloom episodes occur. In this review, the different effects of both of these cyanotoxins on the different ontogenic stages of various fish species were summarised to clarify the state-of-the-art scientific knowledge on this topic.

Cloning and Expression of Genes for Biodegrading Nodularin by Sphingopyxis sp. USTB-05

open access: yesToxins, 2019
Biodegradation is efficient for removing cyanobacterial toxins, such as microcystins (MCs) and nodularin (NOD). However, not all the microbial strains with the microcystin-biodegrading enzymes MlrA and MlrC could biodegrade NOD.

Transcription regulation of hepatotoxins microcystin and nodularin from cyanobacteria [PDF]

open access: yes, 2008
The role and function of hepatotoxins microcystin and nodularin produced by M.aeruginosa PCC 7806 and N. spumigena NSORlO respectively have yet to be elucidated.
