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.

Model predicts coastal paralytic shellfish toxicity in mussels from in situ phytoplankton concentrations. [PDF]
Limnol OceanogrAbstract Harmful algal blooms (HABs) of Alexandrium catenella occur annually in the Gulf of Maine, leading to accumulation of paralytic shellfish toxins (PSTs) in bivalve mollusks and closure of harvesting areas. State monitoring programs in the region rely on weekly shellfish sampling and toxin analysis, requiring extensive effort with limited ...

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

Phytoplankton growth and potential cyanotoxin production differ in response to nitrogen and phosphorus amendments in late summer communities from Kabetogama Lake (Minnesota, United States). [PDF]
J PhycolAbstract Cyanotoxins such as microcystin (MC), cylindrospermopsin, and saxitoxin are secondary metabolites that are rich in nitrogen (N). Most cyanobacteria grow best on reduced inorganic N (ammonium, NH4), but when NH4 is absent, cyanobacteria can activate physiological pathways to process other N forms (e.g., nitrate; NO3).
