Draft:Coral reef cyanobacteria

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

Cyanobacteria are prokaryotes
Historically cyanobacteria were labelled "blue-green algae", however Stanier et al. (1978) 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 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."
