''Aphanizomenon flos-aquae'' (; is a species of cyanobacteria (blue-green algae) which is commercially processed into a dietary supplement. ''Aphanizomenon flos-aquae ''(AFA) is known to contain nutrients including essential fatty acids, active enzymes, vitamins, amino acids, minerals, proteins, complex carbohydrates, and phytochemicals and is marketed as a nutritional supplement. == Biology == Like other cyanobacteria and plants, AFA uses photosynthesis to produce the food material (glycogen) that is stored and utilized by the cell. While plants' cell walls are mainly cellulose, AFA's'' ''cell walls are composed of peptidoglycan (carbohydrates and peptides), the typical cell wall material of bacteria. Therefore, the designation "cyanobacteria" (Latin, cyano = blue-green) refers to the blue-green coloration of this bacterial subdivision, including AFA. The cellular structure of AFA is that of a simple prokaryote. Most cyanobacteria are highly efficient photosynthesizers, even more so than plants. Algae utilize light energy from the sun, carbon dioxide from the air, and water to synthesize proteins, carbohydrates, and lipids. AFA is also able to directly use molecular nitrogen from the air to produce proteins and other nitrogen-containing biomolecules. This ability is widespread in prokaryotes, but unknown in eukaryotes.
