Downstream processing of biomass produced in aquaculture wastewater for valuable pigments from the cyanobacterium Spirulina (Arthrospira) platensis: a green and sustainable approach

Aquaculture wastewater is suitable for algal growth especially due to its ammonium and nitrate content. Therefore, the can be utilized after a few amendments biomass production recovery of valuable pigments. In present study, aquaculture discharged from Pangasius culture system was commercially cyanobacterium Spirulina (Arthrospira) platensis with an aim extract economically important pigments (phycocyanin carotenoids). The amended nutrients used as medium S. platensis. removal effluent-based during period also monitored. A significant increase in rate (0.21 day?1), productivity (23.65 mg g?1 lowest doubling time (3.37 days) noticed decontaminated wastewater. produced showed phycocyanin content (132.45 DW), total carotenoids (1.26 protein (630 DW). nutrient up 97.34% NH+4-N, 71.93% NO?3-N, 95.90% NO?2-N, 93.39% PO43?-P. report provides piece convincing evidence that candidate species utilization cost-effective improvement quality through phycoremediation.
