Enhanced Arthrospira platensis Biomass Production Combined with Anaerobic Cattle Wastewater Bioremediation.

ABSTRACT: Microalgae biomasses offer important benefits regarding macromolecules that serve as promising raw materials for sustainable production. In the present study, the microalgae Arthrospira platensis DHR 20 was cultivated in horizontal photobioreactors (HPBR), with and without temperature control, in batch mode (6 to 7 days), with anaerobically digested cattle wastewater (ACWW) as substrate. High dry biomass concentrations were observed (6.3-7.15 g L^-1). Volumetric protein, carbohydrate, and lipid productivities were 0.299, 0.135, and 0.108 g L^-1 day^-1, respectively. Promising lipid productivities per area were estimated between 22.257 and 39.446 L ha^-1 year^-1. High CO₂ bio-fixation rates were recorded (875.6-1051 mg L
