Effects of CO₂ and liquid digestate concentrations on the growth performance and biomass composition of <i>Tetradesmus obliquus</i> and <i>Chlorella vulgaris</i> microalgal strains.

ABSTRACT: This study evaluated the growth performance of Tetradesmus obliquus and Chlorella vulgaris microalgae cultivated in diluted liquid digestate supplemented with CO₂, comparing their efficiency to that of a conventional synthetic media. The presence of an initial concentration of ammonium of 125 mg N-NH₄ ⁺.L^-1 combined with the continuous injection of 1% v/v CO₂ enhanced the optimal growth responses and bioremediation potential for both strains in 200-mL cultures. In 6-L flat panel reactors, T. obliquus exhibited superior biomass production, achieving a final biomass concentration of 1.29 ± 0.06 g.L^-1, while C. vulgaris reached only 0.36 ± 0.02 g.L^-1. Both strains effectively contributed t
