Bacterial degradation of paralytic shellfish toxins

Toxicon, 2008
Bacteria isolated from the digestive tracts of blue mussels (Mytilus edulis) contaminated with paralytic shellfish toxins (PSTs) were screened for the ability to reduce the toxicity of a PST mixture in vitro. Bacteria were isolated on marine agar and grown in marine broth supplemented with a mussel extract and an algal extract containing PSTs ...

PARALYTIC SHELLFISH TOXINS SEEM ABSENT IN EXTRACTS OF DIARRHETIC SHELLFISH TOXINS

Environmental Toxicology and Chemistry, 1991
Abstract It has been assumed that the water-soluble paralytic shellfish toxins are extracted and concentrated by the organic-solvent extraction method used for diarrhetic shellfish toxins. As diarrhetic toxin extracts of mussels with high levels of paralytic toxins are found nontoxic, it appears that paralytic toxins are not present in ...

Paralytic shellfish toxins and associated toxin profiles in bivalve mollusc shellfish from Argentina

Harmful Algae, 2020
Paralytic Shellfish Poisoning is a potentially fatal syndrome, resulting from the filter-feeding activities of marine molluscs accumulating harmful neurotoxins naturally occurring in microalgae. Outbreaks are well recognised throughout most regions of the world, but with the highest levels of toxicity to date recorded in mussels from Argentina.

Fluorometric Detection of Paralytic Shellfish Poisoning Toxins

Analytical Biochemistry, 1998
A rapid qualitative screening method was developed for the fractionation of paralytic shellfish poisoning toxins. Periodic acid, t-butyl hydroperoxide, and hydrogen peroxide were tested as oxidants for the fluorometric detection of paralytic shellfish toxins.

Electrophoretic analysis of paralytic shellfish toxins

Journal of Environmental Science and Health . Part A: Environmental Science and Engineering, 1977
Abstract Seven paralytic shellfish poisons (PSP) from the dinoflagellate Gonyaulax tamarensis and PSP infested shellfish have been separated by cellulose acetate membrane strip electrophoresis. The acid hydrolysis products of two of these, saxitoxin and neosaxitoxin, are analyzed by electrophoresis.

Synthesis of Paralytic Shellfish Toxins: Saxitoxins

2020
Saxitoxin (STX), which is isolated as a paralytic shellfish toxin, is an inhibitor of voltage-gated sodium channels (NaVCh) such as tetrodotoxin. STX has two guanidine functional groups in its tricyclic core structure, and every carbon except at C11 connects heteroatoms.

Solid-Phase Radioreceptor Assay for Paralytic Shellfish Toxins

Analytical Biochemistry, 1993
Sodium channels obtained from rat brain membrane preparations were coated onto microtiter plates and used to develop a direct solid-phase binding assay. The tritiated sodium channel blocker saxitoxin ([3H]-saxitoxin; STX) was used to detect toxins in paralytic shellfish poisoning (PSP) by measuring the competitive displacement of other toxins.

Instrumental Methods for Paralytic Shellfish Toxins

2015
Paralytic shellfish toxins (PSTs) are naturally occurring marine compounds which in some instances result in significant consumer sickness following consumption of contaminated shellfish products. The toxins are found in shellfish grown in marine waters throughout the world, and many instances of human intoxication are reported annually.

Performance of different extraction methods for paralytic shellfish toxins and toxin stability in shellfish during storage

Analytical and Bioanalytical Chemistry, 2021
Accurate analysis of paralytic shellfish toxins (PSTs) in shellfish is important to protect seafood safety and human health. In this study, the performance of different extraction protocols for PSTs from scallop tissues is compared and discussed, including regular extraction solvents hydrochloric acid (HCl) and acetic acid (AcOH) followed by heating ...

Laboratory bioproduction of paralytic shellfish toxins in dinoflagellates

2001
Publisher Summary It is feasible to produce milligram quantities of Paralytic shellfish toxins (PSTs) as a supply of the pure toxins for R&D and monitoring studies using the algal culture approach. PSTs are a family of marine biotoxins produced by a number of toxic dinoflagellates involved in harmful algal blooms or red tides.
