Toxicity profiles between strains of Alexandriumtamiyavanichii

Phycotoxins are byproducts of toxic microalga that capable of causing severity on humans upon consuming contaminated seafood. The amount of toxins released by microalgae varies according to species as some of the microalgae synthesize toxins within small number of cells while others required a bloom...
