Formulation of Cost-effective Medium Using Urea as a Nitrogen Source for Arthrospira platensis Cultivation under Real Environment

Puganeswary Sukumaran, Rosimah Nulit, Normala Halimoon, Sanimah Simoh, Hishamuddin Omar & Ahmad Ismail · Annual Research & Review in Biology · 2018

Even though Arthrospira is a well-known superfood, it is not extensively commercialized in developing countries like Malaysia due to the high production cost with low biomass yield. Based on literature, the algal production cost can be discounted by reducing the cost of medium ut...
