Spirulina platensis is a filamentous Cyanobacterium with a high content of protein and essential vitamins that are commercially produced for feed and food supplementation. The present study was carried out to utilize the fermented oil cake filtrate as organic nutrient supplementation for Spirulina platensis cultivation. Commonly,the cultivation of is done with conventional Zarrouk media that requires a high quality of NaHCO3. To reduce the cost of the medium different concentration of baking soda, sea salt, along with fermented oil cake filtrate were used as media for the cultivation of Spirulina platensis. Since there is a greater demand for organically grown Spirulina this study was undertaken. The main objective of this work is to cultivate Arthrospira S. platensis in edible oil cake incorporated medium. | Cultivation of spirulina using low-cost organic medium and preparation of phycocyanin based ice creams
