Cyanotoxins are toxin produced by cyanobacterial cells; cyanobacteria is also known as blue green algae, however, some cyanobacteria species are capable to release toxins into the water without cell rupture or death, the release of these toxins in an algal bloom into the surrounding water occurs mostly during cell death and lysis as opposed to continuous excretion from the cyanobacterial cells, these are the most commonly identified cyanotoxins are microcystins, cylindrospermopsin, saxitoxins and anatoxins.
