The purpose of this study was to investigate whether </span> <i> <span style="font-size:14px;">A. platensis </span> </i> <span style="font-size:14px;">biomass production could be performed regardless of high light intensity. Biomass, chlorophyll, lipid and carbohydrate contents were determined by spectrophotometrically. Also the physicochemical properties of the produced cyanobacterium were investigated by FTIR, TGA and DSC. </span> <span style="font-size:14px;">  </span> <span style="font-size:14px;">The highest biomass productivity was detected as 1.33 g/L/day in the medium containing 2.5 mM sucrose and </span> </span> </span> <span class="fontstyle01"> <span lang="en-gb" style="font-size:14px;" xml:lang="en-gb">the specific growth rate increased 1.32 fold as compared to phototrophic culture.
