Cyanotoxin Threats to Animals

Journal Title:Open Access Journal of Biomedical Science

Cyanobacteria, also known as blue-green algae, are a group of photoautotrophic prokaryotes that grow in various habitats mainly freshwater all over the earth due to their strong adaptability to different environments. They can proliferate explosively and outgrow other freshwater microalgae once their optimal growth requirements are met such as enough nutrients and sunlight radiation, and warm weather. Their drastic proliferation always leads to a natural ecological disaster called cyanobacterial Harmful Algal Bloom (cyanoHAB), in which the culpable cyanobacteria are dominant in primary producer communities. CyanoHABs can exhaust key nutrients for other microalgae and thus inhibit their growth, and bacterial decomposition of excessive dead cyanobacterial cells can massively consume dissolved oxygen, creating deadly hypoxic (low oxygen) environment to aquatic organisms.
