Spirulina is a cyanobacterium that can be consumed by humans and other animals; there are two species, Arthrospira platensis and Arthrospira maxima. Arthrospira is cultivated worldwide; used as a dietary supplement as well as a whole food; and is also available in tablet, flake and powder form. It is also used as a feed supplement in the aquaculture, aquarium and poultry industries.
A spirulina is a spiral algae that grows in fresh-water bodies. This algae provides different benefits.
In growing spirulina, an important thing to consider is your budget or capital. This will let you determine the quantity of spirulina you can grow.
Spirulina is a blue-green algae that grows in warm conditions in alkaline water, enriched with bio-gas slurry--an anaerobic fermented sludge of organic manure and water. It is grown for its use as a protein and vitamin source. Growth is carefully controlled so that there is no chance of contamination from other algae. The Envis Centre in India has developed a system for villages to grow spirulina as a source of protein, using their own sewer sludge as the biogas slurry. The spirulina culture starter is available from The University of Texas.
