Los heterocistos son células especializadas fijadoras de nitrógeno formadas por la necesidad de nitrógeno por algunas cianobacterias filamentosas. Estas pueden formar diferentes tipos de células especializadas: acinetos, hormogonios y heterocistos. Las cianobacterias que pueden formar heterocistos son Nostoc punctiforme, Cylindrospermum y Anabaena sphaerica. Fijan nitrógeno del aire usando la enzima nitrogenasa, para proporcionar a las células del filamento c…
