Abstract Microalgae have a high content of antioxidant compounds (carotenoids, phycobilins and fatty acids) used in biotechnology industry. Under stress conditions Dunaliella cells produce more carotenoids. Because of this, we evaluated growth, biomass and carotenoid production under control (indoor) and outdoor conditions using mass cultures of Dunaliella tertiolecta Butcher, under nitrogenlimited media. Control medium was f/2 (nitrates: 18.75 g/L), and limited media were f/4 (nitrates: 37.5 g/L), f/6 (nitrates: 25 g/L) and f/8 (nitrates: 18.75 g/L). The highest cell concentrations were found in cultures using medium f/2 maintained indoor (1.28 x 106 cells/mL) and outdoor (0.76 x 106 cell/mL). Dry biomass… More >
