Coral reef cyanobacteria

[edit]

Coral reef ecosystems host many organisms. One important group of coral reef organisms are cyanobacteria. Some cyanobacteria proliferate on coral reefs after eutrophication events, [1] however other species of cyanobacteria are integral to coral reef ecosystems [2]

Cyanobacteria are prokaryotes

[edit]

Historically cyanobacteria were labelled "blue-green algae", however Stanier et al. (1978)[3] described cyanobacteria as typical prokaryotes so proposed that cyanobacteria should not be classified among eukaryotic algae. Cyanobacteria are taxonomically now considered a phylum under the kingdom Bacteria [4] So what exactly is a cyanobacterium? A redefinition of cyanobacteria by Garcia-Pichel et al. (2020) is as follows:

Cyanobacteria definition:

"Organisms in the domain bacteria able to carry out oxygenic photosynthesis with water as an electron donor and to reduce carbon dioxide as a source of carbon, or those secondarily evolved from such organisms."[5]
