These methods can vary greatly in their degree of sophistication and the information they provide. These methods include: Enzyme–linked immunosorbent assays (ELISA) Cyanotoxins are produced and contained within the cyanobacterial cells (intracellular). The release of these toxins in an algal bloom into the surrounding water occurs mostly during cell death and lysis (i.e., cell rupture) as opposed to continuous excretion from the cyanobacterial cells. However, … See more Blue-green algae, more correctly known as cyanobacteria, are frequently found in freshwater systems. They can also be found in estuarine … See more The most commonly found cyanotoxins in the U.S. are microcystins, cylindrospermopsin, anatoxins and saxitoxins. See more Cyanotoxins can be produced by a wide variety of planktonic cyanobacteria. Some of the most commonly occurring genera are Microcystis, Dolichospermum (previously Anabaena), and Planktothrix.
