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

Cyanotoxins Occurrence in Portugal: A New Report on Their Recent Multiplication
Toxins, 2020 Historical reports show that in Portugal, cyanotoxins reports were mainly in the Center (cylindrospermopsins) and South (cylindrospermopsins, saxitoxins) regions of the country apart from the well distributed microcystins.

Cyanotoxins: methods and approaches for their analysis and detection [PDF]
, 2017 Cyanotoxins are secondary metabolites produced by cyanobacteria, a group of photosynthetic prokaryota especially found in freshwater. In favourable conditions (i.e. high nutrient levels, light intensity, water temperature), cyanobacteria can form blooms,

Review on Cyanobacterial Studies in Portugal: Current Impacts and Research Needs
Applied Sciences, 2021 Cyanobacteria have long been associated with harmful effects on humans, animals and aquatic biota. Cyanotoxins are their most toxic metabolite. This review summarizes the current research, impacts and future needs in cyanobacterial studies undertaken in ...

Microcystin Prevalence throughout Lentic Waterbodies in Coastal Southern California. [PDF]
, 2008 Toxin producing cyanobacterial blooms have increased globally in recent decades in both frequency and intensity. Despite the recognition of this growing risk, the extent and magnitude of cyanobacterial blooms and cyanotoxin prevalence is poorly ...

Multiple New Paralytic Shellfish Toxin Vectors in Offshore North Sea Benthos, a Deep Secret Exposed
Marine Drugs, 2020 In early 2018, a large easterly storm hit the East Anglian coast of the UK, colloquially known as the ‘Beast from the East’, which also resulted in mass strandings of benthic organisms.
