SPIRULINA PLATENSIS - FOOD FOR FUTURE: A REVIEW

Spirulina can play an important role in human and animal nutrition, environmental protection through wastewater recycling and energy conservation. The present review was focused on the various characteristics of Spirulina platensis. Spirulina is rich in proteins (60-70%), vitamins and minerals used as protein supplement in diets of undernourished poor children in developing countries. One gram of Spirulina protein is equivalent to one kilogram of assorted vegetables. The amino acid composition of Spirulina protein ranks among the best in the plant world, more than that of soya bean. The mass cultivation of Spirulina is achieved both in fresh water and waste water. Spirulina grown in clean waters and under strictly controlled conditions could be used for human nutrition. The micro alga grown in waste water is used as animal feed and provide a source of the fine chemicals and fuels. The waste water system is highly applicable in populated countries like India where wastes are generated in high quantities and pose environmental problem. The present review focused the following topics: Spirulina platensis, Isolation and occurrence of Spirulina platensis, newly formulated media for Spirulina cultivation, Phycocyanin and Medicinal properties of Spirulina platensis.
