“…Regarding environmental aspects, the cultivation of algae can be performed in smaller spaces when compared to traditional agriculture and their production can be derived from agro-industrial by-products, thus creating not only an environmental friendly system, but also boosting circular economy, as discussed in Section 8. Moreover, they are capable to remove 10-50 times more CO 2 than land plants, making them the perfect candidate to supply a very significant fraction of food demand with the least environmental impact (de Mendonça et al, 2021). However, algae have some challenges with respect to their use as food product or ingredient, namely the intense undesirable colour and strong "sea" taste and flavour associated with pigments and sulphur-containing compounds and lipid-derived volatiles, respectively, negatively influencing the sensorial attributes of the end product (Batista et al, 2013;Lafarga, 2019;Roohinejad et al, 2017).…”

“…In comparison with terrestrial plants cultivation, microalgae has higher concentrations of chlorophyll per unit area of production, resulting in a cO 2 removal that is 10 to 50 times higher, which represents 1.83 kg of cO 2 per kg of algal biomass (Mendonça et al, 2021;Raeesossadati et al, 2014).…”

“…Microalgae exhibit high photosynthetic rates compared to higher plants [ 14 ], leading to high biomass productivity. In addition, they display the ability to develop in unsuitable agriculture areas [ 15 ], avoiding food security-associated conflicts, and can be produced during the wastewater treatment, thus categorized as a nutrient recycling process, requiring no potable water for cultivation [ 16 ].…”

Enhanced Arthrospira platensis Biomass Production Combined with Anaerobic Cattle Wastewater Bioremediation

et al. 2021

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.
