Efficient Removal of Nitrogen/ Phosphorous by Mix-Cultivation of Haematococcus Pluvialis and Simplicillium Lanosoniveum in Waste Water Supplemented with Nahco3
To remove nutrients efficiently, the mix-cultivation of astaxanthin-producing green alga Haematococcus pluvialis and antibiotic-synthesizing fungus Simplicillium lanosoniveum DT06 (DT06) was conducted in unsterilized wastewater without/with addition of NaHCO3. Results showed that (1) COD, nitrogen and phosphorus removal efficiency were promoted to (100%), (83.3%) and (88.2%) respectively in mixed culture at the optimal cell ratio 30: 1; (2) nitrogen and phosphorus removal efficiency were further promoted to (100%) after addition of NaHCO3 to mixed culture at the optimal concentration 0.3 g L–1 with concurrent increases of algal biomass, lipid and astaxanthin contents to (1.95) g L–1, (0.39) g g–1 and (27.9) mg g–1 respectively. Hence, mix-cultivation of H. pluvialis and DT06 supplemented with NaHCO3 provide a cost-effective strategy for wastewater treatment and biodiesel/astaxanthin production
