MeSH Heading: Cyanobacteria
Tree Number(s): B03.280; B03.440.475.100
Unique ID: D000458
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D000458
Annotation: general or unspecified; prefer specifics; do not confuse entry term CYANOPHYCEAE with CYANOPHORA
Scope Note: A phylum of oxygenic photosynthetic bacteria comprised of unicellular to multicellular bacteria possessing CHLOROPHYLL a and carrying out oxygenic PHOTOSYNTHESIS. Cyanobacteria are the only known organisms capable of fixing both CARBON DIOXIDE (in the presence of light) and NITROGEN. Cell morphology can include nitrogen-fixing heterocysts and/or resting cells called akinetes. Formerly called blue-green algae, cyanobacteria were traditionally treated as ALGAE.
