Occurrence and Diversity of Cyanotoxins and Retinoid Compounds in Antarctic Microbial Mats: Evidence From James Ross Island. [PDF]

Environ Microbiol Rep
Occurrence and distribution of cyanotoxins and retinoids across different Antarctic ecosystems at James Ross Island. These ecosystems harbour diverse microbial communities dominated by autotrophic cyanobacteria and algae, which can produce hazardous compounds for animals.

Nutrient-driven regulation of saxitoxin gene expression and toxin production in Raphidiopsis raciborskii (Cyanobacteria). [PDF]

J Phycol
Abstract Raphidiopsis raciborskii is a diazotrophic cyanobacterium, globally distributed in aquatic environments and known for forming toxic blooms, thereby affecting ecosystem services. South American strains are producers of saxitoxins, potent neurotoxins harmful to humans and animals.

Production of antibodies for saxitoxin analysis and sensitivity analysis of anti-saxitoxin antiserum

Journal of the Korea Academia-Industrial cooperation Society, 2012
해양미세조류 유래 독성물질에 대한 이해와 활용에 있어서 가장 중요하지만 간과되고 있는 부분은 독성물질을 검출할 수 있는 빠르고, 쉽고 경제적인 검출기술을 개발하는 것이다. 이 논문에서 우리는 삭시톡신(STX)에 대한 항체를 생산하였다. 헤모시아닌(mariculture keyhole limpet hemocyanin, mcKLH)과 오브알부민(ovalbumin, OVA)을 운반단백질로 사용하였다. 면역반응을 위해서 mcKLH-STX 결합체를 BALB/c 쥐에 복강주사하였다. 채혈 후 항-STX 항혈청을 분리하였다.

A simple electrochemical aptasensor for saxitoxin detection

RSC Advances, 2022
In this study, a simple electrochemical aptasensor for saxitoxin (STX) detection was developed based on a short anti-STX aptamer with a methylene blue (MB) incorporated at the 3′-end.

Elevated CO2 significantly increases N2 fixation, growth rates, and alters microcystin, anatoxin, and saxitoxin cell quotas in strains of the bloom-forming cyanobacteria, Dolichospermum.

Harmful Algae, 2022
The effect of rising CO2 levels on cyanobacterial harmful algal blooms (CHABs) is an emerging concern, particularly within eutrophic ecosystems. While elevated pCO2 has been associated with enhanced growth rates of some cyanobacteria, few studies have ...

Discovery of nuclear-encoded genes for the neurotoxin saxitoxin in dinoflagellates. [PDF]

PLoS ONE, 2011
Saxitoxin is a potent neurotoxin that occurs in aquatic environments worldwide. Ingestion of vector species can lead to paralytic shellfish poisoning, a severe human illness that may lead to paralysis and death.

Origin of saxitoxin biosynthetic genes in cyanobacteria. [PDF]

PLoS ONE, 2009
BACKGROUND:Paralytic shellfish poisoning (PSP) is a potentially fatal syndrome associated with the consumption of shellfish that have accumulated saxitoxin (STX). STX is produced by microscopic marine dinoflagellate algae.

Domoic acid and saxitoxin in seabirds in the United States between 2007 and 2018.

Harmful Algae, 2021
As harmful algal blooms (HABs) increase in magnitude and duration worldwide, they are becoming an expanding threat to marine wildlife. Over the past decade, blooms of algae that produce the neurotoxins domoic acid (DA) and saxitoxin (STX) and documented ...
