The mixture of EMCs consisted of three pharmaceuticals, diclofenac (DCF), sulfadiazine (SDA), and oxytetracycline (OTC), and the plastics precursor bisphenol A (BPA). Continuous cultures were carried out for 27 days in a set of four columns of photobioreactors connected in series to investigate the daily EMCs and nutrient recovery. Picocystis was able to grow in contaminated wastewater with daily biomass productivity of 0.5 +/- 0.05 g L-1 d-1. Picocystis exhibited high daily EMCs removal efficiencies reaching 100 %, 83-92 %, 93-95 %, and 66-70 % of 1 mg L-1 initial concentration of OTC, DCF, BPA, and SDA, respectively. Besides, Picocystis showed daily nutrient recovery rates of 40 % for nitrogen and total organic carbon and 27 % for phosphorus.These results pointed to the promising application of Picocystis in a continuous bioremediation system for the removal of emerging contaminants and nutrients from wastewaters. specialized Microalgae Wastewater Removal efficiency Emerging contaminant Nutrient recovery TUNISIE SFAX 084 038 062 102 66 102804 [7 ] 2022 2211-9264 https://www.documentation.ird.fr/hor/fdi:010086140 10.1016/j.algal.2022.102804 2211-9264 [F B010086140] https://www.documentation.ird.fr/hor/fdi:010086140 https://www.documentation.ird.fr/intranet/publi/2022-11/010086140.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2022-11-09 2025-02-24 fdi:010086140 fre
