Coupling Nutrient Removal and Biodiesel Production by the Chlorophyte Asterarcys quadricellulare Grown in Municipal Wastewater

Freshwater deficiency and growing requests for renewable energy have led to increased concern about water security. Therefore, the present study attempted evaluate feasibility of using wastewater (WW) as a culture medium microalgal cultivation with aim nutrient removal biodiesel production. The green microalga Asterarcys quadricellulare (Chlorophyta) was isolated from treatment plant in Menoufia, Egypt, grown 24 days Bold’s Basal Medium control at different concentrations secondary treated WW distilled (25%, 50%, 75%, 100%). results 75% recorded 96.6%, 98.4%, 89.9% efficiency nitrate, ammonia, total phosphorus, respectively. Also, it revealed high biomass yield productivity (1.44 g L−1 69.0 mg day−1, respectively). In addition, showed higher lipid production (360.6 L−1) (17.2 day−1). fatty acid profile estimation elevated proportions oleic (54.92%), palmitic (20.54%), linoleic acids (13.9%). Most properties derived studied are consistent those recommended by international standards. current concluded that A. could be used bioremediation potential feedstock.
