The use of reflector film in a cyanobacteria culture rack provides a good light intensity. The effect of light intensity on Spirulina platensis biomass, phycobiliprotein and amino acid content using KNO<SUB>3</SUB> and urea as a nitrogen sources were studied. Maximum biomass productivity 6.9 mg ml<SUP>-1</SUP>and 6.1 mg ml<SUP>-1</SUP> with light reflector (LR) + urea and LR + KNO<SUB>3</SUB> respectively, were noticed. The C-phycocyanin (148.1 +/- 2.2 mg g<SUP>-1</SUP>) and allophycocyanin (45.2 +/- 0.94 mg g<SUP>-1</SUP>) contents were reached maximum at 4 klx. The rack system with reflector gave good effect of light intensity (4.8-6.0 klx) than the normal system (2-3 klx). Results showed that reflector used cultivation improved biomass, proteinic pigments and protein biosynthesis in S. platensis. This method of cultivation is simple, inexpensive and requires low energy.
