The term “microcystin” refers to a group a group of liver toxins that are produced by many species of cyanobacteria. The name microcystin comes from the genus Microcystis, which is one of the most widely know genera that produce this widespread toxin. Microcystis aeruginosa is one of the most common producers of microcystin, and is often associated with eutrophic fresh water systems, where they form large, toxic blooms, though they have been found in marine environments as well. Microcystin contaminated water pose a major health risk for both humans and animals, and have been known to cause mass die offs in contaminated ecosystems as well as the disruption of major food webs.[1] Understanding what causes Microcystis aeruginosa blooms and what leads to the elevated toxicity of these cyanobacteria is imperative to keep humans, animals, and our ecosystems safe.
