Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
Blue-green algae, known as cyanobacteria or harmful algal blooms (HABs), has been confirmed at Devils Lake in Manitou Beach, a news release from the Lenawee County Health Department said.
Klamath Lake AFA, also called Klamath Lake Blue Green Algae and Klamath AFA (Aphanizomenon flos-aquae MDT14a), is a strain of Aphanizomenon flos-aquae. Small amounts of this cyanobacteria can be found in bodies of water worldwide, [ 1 ] but it is notable for growing prolifically in Upper Klamath Lake , Oregon .
Microcystis aeruginosa is a species of freshwater cyanobacteria that can form harmful algal blooms of economic and ecological importance. They are the most common toxic cyanobacterial bloom in eutrophic fresh water. Cyanobacteria produce neurotoxins and peptide hepatotoxins, such as microcystin and cyanopeptolin. [1]
When visiting a lake or other body of water, be on the lookout for any yellow or red warning signs that will inform visitors of toxic algae and closures as well as algae blooms. Blue-green algae ...
The EPA considers microcystis aeruginosa, the toxic cyanobacteria also known as blue-green algae, harmful to humans at a concentration of 8 parts per billion.While most spots tested in Lake O ...
Microcystins—or cyanoginosins—are a class of toxins produced by certain cyanobacteria, commonly known as blue-green algae. [3] Over 250 [4] different microcystins have been discovered so far, of which microcystin-LR is the most common. Chemically they are cyclic heptapeptides produced through nonribosomal peptide synthases. [5]
The prefix cyan comes from the Greek κύανoς meaning "a dark blue substance", [19] and usually indicates any of a number of colours in the blue/green range of the spectrum. Cyanobacteria are commonly referred to as blue-green algae. Traditionally they were thought of as a form of algae, and were introduced as such in older textbooks.
