dc.description.abstract(Excerto introdução) In the present work, C. zofingiensis was cultivated in five different media with respect to nitrogen concentration and source. Higher carotenoids content was observed in biomasses cultivated with higher nitrogen concentration, BBM (U) and BBMSTD, 1.24 and 1.17 mg·g-1, respectively. Moreover, the highest chlorophyll accumulation found in the control condition (10.32 mg·g-1). In contrast, when the nitrogen concentration was reduced, the carotenoids content was almost threefold higher using urea as nitrogen source (0.71 as opposed to 0.22 mg·g-1). Higher lipids accumulation was observed in tenfold nitrogen-reduced media, 45.1 and 40.8 % (BBM (-) and BBM (U-), respectively). Nevertheless, there was no statistical difference between the results of lipids content obtained in NaNO3 and urea media with same nitrogen concentration. Finally, replacing sodium nitrate with urea did not improve the final biomass concentration.pt_PT
