<br/><br/> Microalgal cultivation represents a promising technique for the photosynthetic fixation of CO2 present in gas streams while offering the possibility to produce valuable microalgae-based bioproducts and biofuels. CO2 can be captured using an alkaline solution and subsequently used as an inorganic carbon (IC)source for microalgal cultivation. First, the IC removal and growth properties of P. kessleri were investigated using three synthetic NaHCO3 solutions (1, 5 and 10 g/L)with or without pH control. Results indicated that regularly adjusting the pH to 8.5 had a positive effect on the IC removal as well as on the overall microalgal proliferation. However, even if significant IC removal was achieved (>86.4
