In this experiment, Closterium leibleinii was used as the test material to study the growth and lipid-soluble content of C. leibleinii cultured at different nitrogen and phosphorus concentrations to provide basic information for the development of C. leibleinii as biodiesel. The results showed that the optimum nitrogen concentration was 5.30 mg·L–1 for the growth of C. leibleinii, with the maximum growth rate 3.675×106 cell·L–1·d–1; the optimum phosphorus concentration was 0.02 mg·L–1 with the maximum growth rate 4.05×105 cell·L–1·d–1. The crude lipid accounted for 88.04% of the dry weight of the algae at the optimum NP concentration-BG11. It was concluded that C. leibleinii had a high growth rate and high lipid-soluble material in the medium with optimum nitrogen and phosphorus, and could be developed and utilized as a promising biodiesel.
