Aphanizomenon Flexuosum
''Aphanizomenon'' is a genus of cyanobacteria that inhabits freshwater lakes and can cause dense blooms. These cyanobacteria are unicellular organisms that form linear (non-branching) chains known as trichomes. Parallel trichomes can further unite into aggregates called rafts. Cyanobacteria such as ''Aphanizomenon'' are known for using photosynthesis to create energy and thus rely on sunlight as their energy source. ''Aphanizomenon'' bacteria also play a significant role in the Nitrogen cycle due to their ability to perform nitrogen fixation. Studies on the species ''Aphanizomenon flos-aquae'' have shown that it can regulate buoyancy through light-induced changes in turgor pressure. The genus is also capable of gliding motility, although the specific mechanism responsible for this ability remains unknown.

Aphanizomenon Flos-aquae
''Aphanizomenon flos-aquae'' is a diverse group of cyanobacteria with both toxic and non-toxic strains found in brackish and freshwater environments globally, including the Baltic Sea and the Great Lakes. Cyanobacteria were the first organisms to achieve photosynthesis. Chlorophyll and phycocyanine—two pigments contained in cyanobacteria—allow the vegetative cells to absorb light and transform it into nutrients. Taxonomy and diversity There are two cyanobacterial species in Aphanizomenonaceae having the specific epithet ''flos-aquae'', both appearing in Bornet & Flahault 1886's work on what was then Nostocaceae. The two were morphologically different, being assigned to ''Aphanizomenon'' and ''Anabeana'' respectively. In 2005, Rajaniemi et al. (2005) reported that: * Three samples of ''Ap. flos-aquae'' had cylindrical akinetes and hyaline terminal cells, while the shape varies in five samples of ''An. flos-aquae''. * Four samples of ''Ap. flos-aquae'' end up in one phyloge ...

Aphanizomenon Ovalisporum
''Aphanizomenon ovalisporum'' is a filamentous cyanobacteria present in many algal blooms. Morphology ''Aphanizomenon ovalisporum'' is a filamentous gram negative bacterium of the genus '' Aphanizomenon''. The bacterial filaments are unbranched trichomes. The cells are approximately 5 um in diameter, and are motile through gliding. This species produces two differentiated cells, heterocysts, and akinetes. Metabolism ''Aphanizomenon ovalisporum'' uses oxygenic photosynthesis, like other cyanobacteria. The heterocyst cells of this species can fix nitrogen into ammonium. Genome The genome of ''Aphanizomenon ovalisporum'' is approximately 7.47 Mbp in size, with a GC content of 50.39%. There are 2851 coding sequences. The strain analyzed was isolated in Madrid, Spain. Environment The species was first described during an algal bloom in Lake Kinneret, Israel, 1994. However, other isolates have been obtained from countries around Europe, such as Spain.

Cylindrospermopsis Raciborskii
''Cylindrospermopsis'' is a planktonic genus of filamentous cyanobacteria known for its blooms in eutrophic waters. The type species is the tropical '' Cylindrospermopsis raciborskii'' (Woloszynska) Seenayya & Subbaraju. The cyanotoxin cylindrospermopsin Cylindrospermopsin (abbreviated to CYN, or CYL) is a cyanotoxin produced by a variety of freshwater cyanobacteria. CYN is a polycyclic uracil derivative containing guanidino and sulfate groups. It is also zwitterionic, making it highly water ... was first identified from a species of this genus.
