Cyanotoxins are toxins produced by bacteria called cyanobacteria (also known as blue-green algae). The release of these toxins in an algal bloom into the surrounding water occurs mostly during cell death and lysis (i.e., cell rupture) which leads serious threat to most of the aquatic animals. Cyanotoxins can be produced by a wide variety of planktonic cyanobacteria. Some of the most commonly occurring genera are Microcystis, Anabaena, and Planktothrix (Oscillatoria). For cyanobacteria to bloom on the surface of the water, the environment must have intense light, high pH, high temperature, and an increased accessibility to nitrogen and phosphorous.
