Serving a vital role in the redistribution of energy flux and nutrient cycles in the environment, microalgae have garnered wide attention due to their excellent ability in wastewater phycoremediation with simultaneous resource recovery to synthesize valuable bioproducts for biofuel and other applications. Anaerobic digestate of dairy wastewater is rich in organic carbon and nutrients (P and N), which is well-suited to cultivate microalgae. This study investigated the performance of utilizing untreated anaerobic digestate of dairy wastewater for the cultivation of Chlorella sorokiniana SU-1 to achieve satisfactory removal of nutrients and chemical oxygen demand (COD) as well as the synthesis of biocompounds. High biomass concentration of 4.8 ± 0.08 g/L with compositions of 47.3 ± 1 % carbohydrate, 29.3 ± 11 % protein, and 4.3 ± 3 % lipid content as well as outstanding wastewater treatment performance (91.3 ± 3 % COD removal, 92.1 ± 2 % total phosphorus (TP) removal,...
