Quantitation of diarrhetic shellfish poisoning toxins in Chilean Mussel using pyrenyldiazomethane as fluorescent labeling reagent

open access: yesBiological Research, 2003
Diarrhetic shellfish poisoning (DSP) is a gastrointestinal disease caused by lipid soluble polyether toxins produced by dinoflagellates and accumulated in shellfish.

Structural basis for divergent C–H hydroxylation selectivity in two Rieske oxygenases

open access: yesNature Communications, 2020
Rieske oxygenases are iron-dependent enzymes that catalyse C–H mono- and dihydroxylation reactions. Here, the authors characterise two cyanobacterial Rieske oxygenases, SxtT and GxtA that are involved in the biosynthesis of paralytic shellfish toxins and

Molecular Mechanisms of Algicidal Bacteria in Controlling Harmful Algal Blooms: Advances in Bacteria‐Algae Interactions

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This review elucidates the molecular mechanisms of algicidal bacteria, highlighting critical behaviours like chemotaxis, quorum sensing and extracellular vesicle release. It details how these actions disrupt algal cellular integrity, photosynthesis and calcium homeostasis, providing a theoretical foundation for controlling harmful algal blooms ...

Ingestion of Alexandrium pacificum Cysts by a Deposit Feeder: An Option for Ecosystem‐Based Approach Benefiting Aquaculture and Coastal Communities?

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
Harmful algal blooms caused by the paralytic shellfish toxin‐producing species Alexandrium pacificum have increased in recent years in one of the most important aquaculture regions of New Zealand, the Marlborough Sounds. Reoccurring blooms have created large cysts beds in the sediments throughout the sounds. In this region, large populations of the sea

Analysis of paralytic shellfish toxins in Aphanizomenon DC-1 from Lake Dianchi, China

open access: yes, 2006
Lake Dianchi is in Yunnan Province in southwestern China. In recent years, significant cyanobacterial blooms have occurred in this lake nearly every year because of eutrophication.

Removal of Paralytic Shellfish Toxins by Probiotic Lactic Acid Bacteria [PDF]

open access: yesToxins, 2014
Paralytic shellfish toxins (PSTs) are non-protein neurotoxins produced by saltwater dinoflagellates and freshwater cyanobacteria. The ability of Lactobacillus rhamnosus strains GG and LC-705 (in viable and non-viable forms) to remove PSTs (saxitoxin (STX), neosaxitoxin (neoSTX), gonyautoxins 2 and 3 (GTX2/3), C-toxins 1 and 2 (C1/2)) from neutral and ...

Pernicious Anemia: A Rare Case of Vitamin B12 Deficiency With Hyperpigmentation and Pancytopenia

open access: yesCase Reports in Medicine, Volume 2026, Issue 1, 2026.
The clinical mimicry of vitamin B12 deficiency can often delay its recognition and treatment. Pernicious anemia remains among its major clinical causes. We report the case of a 32‐year‐old male who presented with symptoms of progressive darkened skin, fatigue, general weakness, and neurological symptoms, with examination notable of severe conjunctival ...

Microbial Ecology at the Nexus of Food Safety and Biotechnology With Ecological Mechanisms, Risks, and Emerging Innovations

open access: yesInternational Journal of Food Science, Volume 2026, Issue 1, 2026.
Food systems are complex microbial ecosystems in which microorganisms play dual and often contrasting roles as agents of foodborne contamination and as essential drivers of food production and biotechnological innovation. Microbial ecology provides an integrative framework for understanding how microbial interactions, environmental conditions, and ...
