Cyanobacteria
The taxonomy is currently under revision
Chroococcales (suborders-Chamaesiphonales and Pleurocapsales)
Nostocales (= Hormogonales or Oscillatoriales)
Stigonematales
Cyanobacteria (English pronunciation: /saɪˌænoʊbækˈtɪəriə/; also known as blue-green algae, blue-green bacteria, and Cyanophyta) is a phylum of bacteria that obtain their energy through photosynthesis. The name "cyanobacteria" comes from the color of the bacteria (Greek: κυανός (kyanós) = blue).
The ability of cyanobacteria to perform oxygenic photosynthesis is thought to have converted the early reducing atmosphere into an oxidizing one, which dramatically changed the composition of life forms on Earth by stimulating biodiversity and leading to the near-extinction of oxygen-intolerant organisms. According to endosymbiotic theory, chloroplasts in plants and eukaryotic algae have evolved from cyanobacterial ancestors via endosymbiosis.
