The chemicals of Spirulina Academic Article uri icon


  • Microalgae could be utilized for the production of several chemicals which are either unique to the algae or found at relatively high concentrations and command a high market value. In this respect, Spirulina is one of the more promising microalgae. It is especially rich, relative to other sources, in the polyunsaturated fatty acid y-linolenic acid (GLA), and in pigments such as phycocyanin, myxoxanthophyl and zeaxanthin. Spirulina is an outstanding candidate for outdoor cultivation, being both thermophilic and alkalophilic, with optimum growth conditions being 35—37 C and pH of about 10; these properties facilitate the maintenance of monoalgal cultures outdoors. The high optimum growth temperature is also responsible for increased productivity. The unique chemical composition of Spirulina offers an additional benefit for the large-scale cultivation of this alga. This overview will discuss …
