| Abstract |
The high-salinity and nutrient-rich feature of seafood processing wastewater (SPW) challenges current treatment technologies. Microalgae-based circular economies offer promising solutions to reduce environmental pollution and increase bioproducts production. In this study, we employed industrial capacity demonstrated halophilic microalga Chlorella MEM25 as a model to demonstrate a closed-loop circular bioeconomy. The approach mutually achieves clean water via the reclamation of high-salinity SPW and the production of valuable bioproducts suitable for functional food. With experimentally and computationally optimized parameters, MEM25 grows robustly in SPW-based culture and produces high amounts of essential amino-acid-rich proteins (52.89 +/- 0.65%) and polyunsaturated fatty acid-rich lipids (33.20 +/- 0.59%), which are ideal ingredients for functional food. Moreover, the removal efficiency of phosphate was as high as 98.21%, further demonstrating the advantages of using microalgae to produce functional food and reclaim SPW as an eco-friendly circular model. |
