Many cyanobacteria species produce a group of toxins known as microcystins. The species most commonly associated with microcystin production is Microcystis aeruginosa. Microcystins are cyclic peptides, containing seven amino acids.  They are the most numerous of the cyanotoxins, comprising over 80 analogs. (A712)"}]
