Paralytic Shellfish Toxins in Mollusks from Galicia Analyzed by a Fast Refined AOAC 2005.06 Method: Toxicity, Toxin Profile, and Inter-Specific, Spatial, and Seasonal Variations

open access: yesToxins
Paralytic shellfish poisoning is an important concern for mollusk fisheries, aquaculture, and public health. In Galicia, NW Iberian Peninsula, such toxicity has been monitored for a long time using mouse bioassay.

Oceanography and Pacific Oyster Biochemical Composition in a Novel Oyster‐Growing Region

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 5, October 2025.
ABSTRACT The farming of Pacific oysters (Crassostrea [Magallana] gigas) is a rapidly growing industry in Alaska, where farms represent some of the highest latitude oyster cultivation efforts in the world. Little is known about the nearshore oceanography where Alaskan farms are located, or how the subarctic marine context influences oyster tissue ...

Current situation on analysis of marine toxins

open access: yesReviews in Analytical Chemistry, 2013
Marine toxins are a food safety concern worldwide. This review discusses current analytical methods for those toxins that are legally regulated in Europe, namely domoic acid, saxitoxin, okadaic acid, yessotoxin, pectenotoxin and azaspiracids, and all ...

Filtering efficiency and feeding mechanisms of Daphnia pulex on Microcystis aeruginosa and Nannochloropsis [PDF]

open access: yes, 2012
The filtering and feeding rate of Daphnia pulex from the Old Durham Reservoir, Durham, NH, were measured to determine the feeding efficiency on different concentrations of non-toxic Nannochloropsis (Class Eustigmatophyceae) and toxigenic cyanobacteria ...

The toxic effects of meta‐tyrosine are related to its misincorporation into the proteome and to altered metabolism in cyanobacteria

open access: yesThe FEBS Journal, Volume 292, Issue 20, Page 5439-5456, October 2025.
This study reveals that meta‐tyrosine (m‐Tyr), a nonproteinogenic analog of aromatic amino acids, disrupts protein synthesis and photosynthesis in cyanobacteria by being misincorporated by Phenylalanyl‐tRNA synthetase (PheRS) into essential proteins. Through molecular, biochemical, and proteomic analyses in Synechocystis, the research shows that m‐Tyr ...

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

open access: yesJournal 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 ...

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

open access: yesAmerican 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 ...
