Effect of carbon content, salinity and pH on Spirulina platensis for phycocyanin, allophycocyanin and phycoerythrin accumulation

Abstract

The cyanobacterium Spirulina platensis is an attractive source of the biopigment, which is used as a natural colour in food, cosmetic, pharmaceutical products and have tremendous applications in nutraceuticals, therapeutics and biotechnological research. The present study examines the possibility of increasing the content of Phycocyanin, Allophycocyanin, Phycoerythrin and Carotenoids under stress conditions including different pH, salinity and carbon content in S. platensis isolated from Jalmahal, Jaipur (Rajasthan). The production of Phycocyanin, Allophycocyanin and Phycoerythrin were enhanced with 0.4 M NaCl, pH 7 and Carbon deficiency as compared to standard. © 2014 Sharma G, et al.
