Influence of Nitrogen Concentration on the C-Phycocyanin production of Spirulina platensis (Gomont) Geitler

Abstract

Spirulina platensis is a filamentous cyanobacterium that is widely used as a functional food due to its high nutritional value. A 24-day cultivation of S. platensis was conducted to assess the influence of varying nitrogen concentration in the production of C-phycocyanin (CPC). The CPC concentration, yield and purity were determined. The result showed that the CPC concentration and yield were highest at day 20 with 0.446 ± 0.057 mg/mL and 293.56 ± 78.33 mg/g, respectively. The purity of CPC extracted was highest at day 16 and considered as food grade with purity value from 0.78 to 0.97. This study showed high biomass productivity on nitrogen source.
