摘要：

Simultaneous removal of nutrients (ammonium and phosphate) and COD was investigated by the co-culture consortium of microalga Chlorella vulgaris and bacterium Pseudomonas putida. The co-culture system showed higher removal of both nutrients and COD than the each axenic culture, indicating that nutrients uptake capability of C vulgaris was enhanced in the presence of P. putida. The best performance in the removal of nitrogen, phosphorus, and COD was obtained through the co-culture with suspended P. putida and immobilized C vulgaris, demonstrating that the employment of immobilization of one species is more synergistic than suspended co-culture system in nutrients removal from wastewater.
