First report of a toxic nodularia spumigena (Nostocales/Cyanobacteria) bloom in sub-tropical Australia. II. bioaccumulation of nodularin in isolated populations of mullet (Mugilidae) [PDF]

, 2012
Fish collected after a mass mortality at an artificial lake in south-east Queensland, Australia, were examined for the presence of nodularin as the lake had earlier been affected by a Nodularia bloom.

Development, Validation and Application of a Targeted LC-MS Method for Quantification of Microcystins and Nodularin: Towards a Better Characterization of Drinking Water [PDF]

, 2022
peer reviewedCyanotoxins can be produced in surface waters by cyanobacterial blooms, mostly during summer and early autumn. Intoxications would result from consumption of water contaminated with the potent hepatotoxins, microcystins and nodularin ...

Towards a Better Quantification of Cyanotoxins in Fruits and Vegetables: Validation and Application of an UHPLC-MS/MS-Based Method on Belgian Products

Separations, 2022
Vegetables and fruits can potentially accumulate cyanotoxins after water contaminated with cyanobacteria is used for irrigation. We developed and validated an analytical method to quantify eight microcystin congeners (MCs) and nodularin (NOD) using ultra

Cyanobacteria and Cyanotoxins in Mediterranean Reservoirs: Ecological Variability, Risks and Implications for Water Quality Assessment

Ecohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT The increasing demand for freshwater, in combination with climate change and pollution, compromises the quality and quantity of water resources. These pressures have intensified cyanobacterial blooms, including toxic events that threaten human health and aquatic ecosystems. This study complements the objectives of the Water Framework Directive

Interactive effects of stoichiometry and environmental variability regulate cyanobacteria toxicity in two eutrophic bays

Limnology and Oceanography, Volume 70, Issue 11, Page 3506-3519, November 2025.
Abstract Cyanobacteria blooms are a leading threat to water quality globally. Despite this, the timing and frequency of toxin production associated with harmful blooms are not well understood. Here we explore cyanobacteria bloom dynamics and cyanotoxin production in two heavily instrumented shallow, eutrophic bays of Lake Champlain through the lens of ...

Synthesis of nodularin analogues as potential protein phosphatases inhibitors [PDF]

, 2018
Reversible phosphorylation of proteins on serine, threonine and tyrosine residues, is now widely accepted to be the principal mechanism for the control of intracellular events in eukaryotic and prokaryotic cells.

Incorporation of diazotrophically fixed nitrogen by juvenile fish in a coastal sea

Limnology and Oceanography, Volume 70, Issue 10, Page 2968-2981, October 2025.
Abstract Nitrogen‐fixing cyanobacterial blooms worldwide have been shown to support production in primary consumers such as zooplankton and benthic invertebrates, but there have been few estimates of how much of the cyanobacterial nitrogen ends up in secondary consumers, such as fish.

LC-MS/MS Validation and Quantification of Cyanotoxins in Algal Food Supplements from the Belgium Market and Their Molecular Origins

Toxins, 2022
Food supplements are gaining popularity worldwide. However, harmful natural compounds can contaminate these products. In the case of algae-based products, the presence of toxin-producing cyanobacteria may cause health risks.

Assessing the Impacts of Land‐Use Change and Climate Variability on Cyanobacterial Abundance and Toxicity in Shallow Lakes

Freshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT The global increase in the frequency and intensity of cyanobacteria blooms has been widely attributed to changes in land‐use practices and climate variability, yet little is known of how toxicity has varied historically relative to cyanobacteria abundance.

Nodularin induces tumor necrosis factor-alpha and mitogen-activated protein kinases (MAPK) and leads to induction of endoplasmic reticulum stress [PDF]

, 2016
Nodularin is produced by the cyanobacterium Nodularia spumigena. It is of concern due to hepatotoxicity in humans and animals. Here we investigated unexplored molecular mechanisms by transcription analysis in human liver cells, focusing on induction of
