Cyanobacteria cultured in specific media: Cyanobacteria can be helpful in agriculture as they have the ability to fix atmospheric nitrogen in soil. The unicellular cyanobacterium Synechocystis sp. PCC6803 was the third prokaryote and first photosynthetic organism whose genome was completely sequenced . [ 241 ]
Cyanobacteria are ubiquitous, finding habitats in most water bodies and in extreme environments such as the polar regions, deserts, brine lakes and hot springs. [ 60 ] [ 61 ] [ 62 ] They have also evolved surprisingly complex collective behaviours that lie at the boundary between single-celled and multicellular life.
Cyanobacteria were the first organisms to achieve photosynthesis. [4] 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. [5]
Cyanobionts play a variety of roles in their symbiotic relationships with the host organism. [2] [4] [5] They function primarily as nitrogen- and carbon-fixers.However, they can also be involved in metabolite exchange, as well as in provision of UV protection to their symbiotic partners, since some can produce nitrogen-containing compounds with sunscreen-like properties, such as scytonemin and ...
Cyanobacteria are photosynthetic prokaryotes that have existed on Earth for an estimated 2.7 billion years. The ability of cyanobacteria to produce oxygen initiated the transition from a planet consisting of high levels of carbon dioxide and little oxygen, to what has been called the Great Oxygenation Event where large amounts of oxygen gas were produced.

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]
