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.
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.
Lake Erie in October 2011, during an intense cyanobacteria bloom [1] [2] 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.
Symbiosis in lichens is the mutually beneficial symbiotic relationship of green algae and/or blue-green algae (cyanobacteria) living among filaments of a fungus, forming lichen. [ 1 ] [ 2 ] [ 3 ] Living as a symbiont in a lichen appears to be a successful way for a fungus to derive essential nutrients, as about 20% of all fungal species have ...
Oscillatoria is mainly blue-green or brown-green and is commonly found in watering-troughs. It reproduces by fragmentation forming long filaments of cells which can break into fragments called hormogonia. The hormogonia can then grow into new, longer filaments.
What is blue-green algae? 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.
Depending on the organism, its pigments, and the depth in the water column, algal blooms can be green, red, brown, golden, and purple. [2] Bright green blooms in freshwater systems are frequently a result of cyanobacteria (colloquially known as "blue-green algae") such as Microcystis.
