In this study, Porphyridium purpureum was cultured in a flat panel photobioreactor systems, with different light path (3, 5 and 7 cm). Lipid, protein, biomass and polysaccharide rate were determined. The highest polysaccharide content (0.48 gL(-1)) for Porphyridium purpureum in the study was obtained from the culture with 1.316 gL(-1) biomass rate, 29,7% protein it the panel PBR system with 3 cm light path. The lowest polysaccharide content and highest protein were found as 0.31 gL(-1), 32.3% respectively, at it the panel PBR system with 7 cm light path. Consequently, Porphyridium purpureum cultured successfully completed in flat panel photobioreactor system at Cukurova Conditions (Adana, Turkey). The best growth was obtained from 3 cm light path photobioreactor system.
