AB  - 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 CO(2) bio-fixation 
      rates were recorded (875.6-1051 mg L(-1) day(-1)), indicating the relevant 
      potential of the studied microalgae to mitigate atmospheric pollution. Carbon 
      concentrations in biomass ranged between 41.8 and 43.6%. ACWW bioremediation was 
      satisfactory, with BOD(5) and COD removal efficiencies of 72.2-82.6% and 
      63.3-73.6%. Maximum values of 100, 95.5, 92.4, 80, 98, and 94% were achieved 
      concerning the removal of NH(4) (+), NO(3) (-), P(t), SO(4) (2-), Zn, and Cu, 
      respectively. Total and thermotolerant coliform removals reached 99-99.7% and 
      99.7-99.9%. This microalgae-mediated process is, thus, promising for ACWW 
      bioremediation and valuation, producing a microalgae biomass rich in 
      macromolecules that can be used to obtain friendly bio-based products and 
      bioenergy. SUPPLEMENTARY INFORMATION: The online version contains supplementary
