dc.description.abstractThe production of metabolites in microalgae is influenced by extreme cultivation conditions. Bicarbonate is an inorganic carbon source for phototrophic microalgae culturing. In this study, the effect of dissolved inorganic carbon (DIC) (0.4–13 g L−1) on the accumulation of metabolites in Dunaliella tertiolecta biomass is presented. The highest levels of primary metabolites [lipid (239.6 ± 24.3 mg g−1), protein (336.2 ± 47.5 mg g−1)], secondary metabolites [total phenolic (12.8 ± 2.0 mg g−1), total flavonoid (14.4 ± 2.3 mg g−1), total ascorbate (4.7 ± 1.1 mg g−1)], and pigments [chlorophyll (27.2 ± 3.1 mg g−1), carotenoid (2.0 ± 0.1 mg g−1)] were observed when cells were grown with 5.7 g L−1 of DIC (NaHCO3). The highest biomass concentrations (1.5 ± 0.1 g L−1) were obtained for cells grown in a mixture of DIC (4.3 + 1.1 g L−1, NaHCO3 + Na2CO3). This study recommends the optimal levels of bicarbonate carbon of 5.7 g L−1 for maximising the generation of metabolites in the biomass. It also demonstrates that exogenous excessive DIC in the growth medium would be an effective stressor to produce high-value metabolites in Dunaliella or alkali-halophilic strains.en_US
