In this study, a newly discovered microalga Parachlorella kessleri QWY28 with a superior ability to treat real swine wastewater, was isolated and explored. The optimal culture conditions of 30 degrees C and 600 mu mol/m(2).s were set to improve the practical application potential, achieving maximum pollutant removal efficiencies of 88% COD, 95% TN and almost 100% TP, with carbohydrate production at 646 mg/L.d. These results present the highest efficiencies reported to date, for non-sterilized real swine wastewater without pretreatment. These findings support the practical feasibility of combined microalgal swine wastewater purification and energy production systems.
