Spirulina are cyanobacteria that grow as multicellular filaments that are helical wiled hence its name. Spirulina are found in soil, thermal springs and waters that range in salinity from to full sea H2O. It has been recorded from waterlogged rice fields. Pards, lakes, watatec channels by spirulina, the water generally has a PH of atleast 10. Being a typical organism, Spirulina is thermophilic, the optima temperature for more strains is 36+(or) – 2 c. Though many strain have been expecimentally cultured, probably the most commonly cultured species are S . platensis & S. maxima.
