cyanobacteriumn.

/ˌsaɪənoʊˌbækˈtɪriəm/

Inflections: Plural cyanobacteria.

Origin: Formed within English, by compounding. Etymons: cyano- comb. form, bacterium n.

Etymology: < cyano- comb. form + bacterium n., with allusion to the green or blue pigments contained in these bacteria.

Microbiology.

Any member of a group of organisms (now the phylum Cyanobacteria), comprising Gram-negative bacteria that carry out oxygen-producing photosynthesis, and occur widely in aquatic and moist habitats. Frequently in plural.Cyanobacteria occur in unicellular, filamentous, and colonial forms; they include free-living organisms and others that live in symbiosis with plants and fungi. Under certain conditions cyanobacteria can form blooms (bloom n.¹ 4e) in water, which may be toxic to other organisms.These organisms were originally thought to be algae, and called blue-green algae because of their blue and green photosynthetic pigments (phycocyanins and chlorophylls). Cf. also cyanophyte n.
