Grazer‐induced bioluminescence and toxicity in marine dinoflagellates

Limnology and Oceanography, Volume 70, Issue 12, Page 3769-3783, December 2025.
Abstract Marine copepods are the most abundant multicellular zooplankton in the global oceans. They imprint their surrounding waters with a unique bouquet of chemical compounds, including polar lipids such as copepodamides. Prey organisms can detect copepodamides and respond by inducing defensive traits including bioluminescence, toxin production ...

Characterization of Benzoyl Saxitoxin Analogs from the Toxigenic Marine Dinoflagellate Gymnodinium catenatum by Hydrophilic Interaction Liquid Ion-Chromatography-Tandem Mass Spectrometry [PDF]

, 2017
The chain-forming marine dinoflagellate Gymnodinium catenatum Graham has a remarkable capacity to produce a wide array of neurotoxic alkaloids associated with Paralytic Shellfish Poisoning (PSP). More than a decade ago, a completely new group of benzoyl

Magnetic Separation-Based Multiple SELEX for Effectively Selecting Aptamers against Saxitoxin, Domoic Acid, and Tetrodotoxin.

Journal of Agricultural and Food Chemistry, 2018
In this study, a novel magnetic separation-based multiple systematic evolution of ligands by exponential enrichment (SELEX) was applied to select aptamers simultaneously against three kinds of marine biotoxins, including domoic acid (DA), saxitoxin (STX),

Using environmental DNA to detect Microseira wollei (Oscillatoriales), a benthic harmful algal bloom, in Lake St. Clair (Michigan, USA)

Limnology and Oceanography: Methods, Volume 23, Issue 12, Page 949-959, December 2025.
Abstract Microseira wollei is a benthic cyanobacterium that can cause harmful algal blooms (HABs) and often requires management. However, a pervasive challenge for M. wollei management is characterizing the spatial and temporal extent of an impacted area, which can be time and resource intensive.

Screening the toxicity and toxin content of blooms of the cyanobacterium Trichodesmium erythraeum (Ehrenberg) in northeast Brasil

Journal of Venomous Animals and Toxins including Tropical Diseases, 2009
Blooms of the cyanobacterium Trichodesmium occur in massive colored patches over large areas of tropical and subtropical oceans. Recently, the interest in such events has increased given their role in major nitrogen and carbon dioxide oceanic fluxes ...

Comparative paralytic shellfish toxin accumulation in three important Aotearoa New Zealand marine invertebrate species: kina (Evechinus chloroticus), pāua (Haliotis iris) and hohehohe (Panopea zelandica)

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1252-1264, December 2025.
ABSTRACT This study investigated the potential for paralytic shellfish toxin (PST) accumulation in three of Aotearoa New Zealand's (NZ) taonga seafood species: kina (urchin; Evechinus chloroticus), pāua (abalone; Haliotis iris) and hohehohe (geoduck; Panopea zelandica) in laboratory exposures to the dinoflagellate Alexandrium pacificum.

Saxitoxin time–resolved absorption and resonance FT–IR and Raman biospectroscopy and density functional theory investigation of vibronic–mode coupling structure in vibrational spectra analysis

American Journal of Experimental and Clinical Research, 2019
Saxitoxin (STX) is a potent neurotoxin and the best–known paralytic shellfish toxin (PST). Ingestion of Saxitoxin by humans, usually by consumption of shellfish contaminated by toxic algal blooms, is responsible for the illness known as paralytic ...
