n. pl. cy·a·no·bac·te·ri·a (-tîr′ē-ə)
Any of various photosynthetic bacteria of the phylum Cyanobacteria that are generally blue-green in color and are widespread in marine and freshwater environments, with some species capable of nitrogen fixation. Also called blue-green alga, blue-green bacterium.
