Spirulina platensis - Definition, Glossary, Details - OilgaeSpirulina platensis is a cyanobacterium that has a high protein content and therefore, a high nutritional value. It can be cultivated either in a liquid or in a solid culture. When cultivated in aqueous culture the cell growth can be determined by following the optical density. On the other hand, when produced by solid cultivation the growth can be determined only indirectly, such as, through determination of the protein content of the fermenting solids - Source
Spirulina platensis is a filamentous cyanobacterium that is biotechnologically important due its high nutritional value. The nutritional value derives from its high protein content (about 70%) and its type of lipids (g-linolenic acid) . This microorganism also finds application in environmental technology .
Generally it is produced in open ponds in liquid culture, but recently, its production in solid-state cultivation systems has been studied. Source
