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.
Microcystin-LR had effects on all animals, not only the domestic animals from swimming in a river of drinking water with cyanobacteria blooms. Symptoms in domestic animal poisoning include diarrhea, vomiting, weakness, recumbency and are fatal in most cases [12] [13] Mircocystin-LR is toxic for all animals, including the animals consumed by humans.
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]
According to the Walworth County DHHS, "Blue-green algae are photosynthetic bacteria known as 'cyanobacteria,' which can cause illness and death in humans and animals. Blue-green algae are a ...
If you have other health questions or concerns about blue-green algae blooms, please call the Florida Department of Health in Okeechobee County at 772-873-4927.
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.
Chlorophyll and phycocyanine—two pigments contained in cyanobacteria—allow the vegetative cells to absorb light and transform it into nutrients. [ 4 ] The genus Aphanizomenon is defined as a cluster of eight morphospecies, including Aphanizomenon flos-aquae .
The name "cyanobacteria" (from Ancient Greek κύανος (kúanos) 'blue') refers to their bluish green color, [5] [6] which forms the basis of cyanobacteria's informal common name, blue-green algae, [7] [8] [9] although as prokaryotes they are not scientifically classified as algae.
