noun
Scientific term for a phylum of photosynthetic bacteria; also called blue-green algae, though they are prokaryotes, not true algae.
シアノバクテリアは酸素を発生する光合成を行う。
Cyanobacteria perform photosynthesis that produces oxygen.
藍藻 is the native Japanese term for cyanobacteria, often used interchangeably but can also refer to blue-green algae in a broader sense.
Borrowed from English 'cyanobacteria', from Greek 'kyanos' (dark blue) + 'bacteria'.
