Anabaena és un gènere de cianobacteris filamentosos (abans anomenats algues blaves) que es troben al plàncton. Like all phototrophic bacteria, A. Azollae uses solar energy along with bacteriochlorophyll and CO2 to carry out photosynthesis in the cytoplasm of its cells. The phycocyanin content and anabbaena phycobilin complement of the symbiotic algae were distinct from those of Anabaena cylindrica and a free-living isolate of the Azolla endophyte. [an΄ə bē′nə] n.

Azolla dikenal mampu bersimbiosis dengan bakteri biru-hijau Anabaena azollae dan mengikat nitrogen langsung dari udara. These Anabaena-free hybrids are extremely important for comparing their genetics, biochemistry and morphology with species that contain Anabaena azollae, so that we can understand (among other things) how they function, why they do not contain Anabaena azollae, and determine if the other bacterial symbionts are present in the forms without Anabaena azollae. anabaena.
