Anabaena - Wikipedia, the free encyclopedia
Anabaena is a genus of filamentous cyanobacteria, or blue-green algae, found as plankton. It is known for its nitrogen fixing abilities, and they form symbiotic relationships with certain plants, s...

Anabaena are heterocyst-forming, photoautotrophic cyanobacteria that perform oxygenic photosynthesis. Anabaena grow in long filaments of vegetative cells. ... Figure A shows normal Anabaena grown in a complete medium. Figure B shows normal Anabaena growing in a medium lacking nitrogen, arrows indicate heterocysts.

Illustrated account of Anabaena (Cyanobacteria) ... In Anabaena the cells are ovoid or barrel-shaped, often giving the filaments (trichomes) the appearance of a string of beads (though this is not so evident in the species photographed).

Anabaena variabilis ATCC 29413 is a filamentous heterocyst-forming cyanobacterium that fixes nitrogen and CO2 using the energy of sunlight via oxygen-evolving plant-type photosynthesis. In addition, this strain has been studied extensively for the production of hydrogen using solar energy.

Anabaena has uniseriate, straight, curved, or coiled trichomes that may be constricted at the cell walls. The blue-green to yellow-green colored cells may be spherical, ellipsoidal, cylindrical, or bent, but overall look much like a string of beads.

The filaments reproduce via fragmentation and by producing akinetes that will later germinate into new filaments. The cells divide perpendicularly to the trichome axis.

Among Maryland’s tidal waters, Anabaena species and Aphanizomenon flos-aquae are frequently found in freshwaters of the Potomac River and the upper Chesapeake Bay. Their greatest abundances are usually observed during the summer.
