Cyanobacteria are oxygenic, phototrophic organisms. They encode two photosystems (PSI and PSII) releasing electrons from water and fix carbon dioxide via the Calvin-Benson-Bassham pathway. Thus they absorb large quantities of CO(2) and produce O(2). Some cyanobacteria are also able to fix N(2). Heterocysts differentiate in response to the lack of nitrogen in the environment and are the sites of nitrogen fixation (3-10% of total cells).

Strain PCC 7122, a heterocyst, was isolated from water, most likely a pond, in the Cambridge, UK in 1939. It fixes nitrogen aerobically in heterocysts. It has been proposed as type strain of the species Anabaena cylindrica (by Rippka et al., J. Gen. Micro. (1979), 111, 1-61). See also
