Characterization of saxitoxin production and release and phylogeny of sxt genes in paralytic shellfish poisoning toxin-producing Aphanizomenon gracile
The freshwater cyanobacterium Aphanizomenon gracile is one of the most widely distributed
producers of the potent neurotoxins saxitoxin (STX) and its derivatives (paralytic shellfish
poisoning toxins, PSP toxins). However, the phylogeny of STX biosynthesis genes and the
regulation of STX production and release remain poorly studied in the genus
Aphanizomenon. In this study, two A. gracile strains from Spanish freshwaters were grown in
semi-continuous cultures under three temperatures (15, 20 and 28° C) and their STX …
