AbstractMicroalgae have already been investigated as a potential resource for biofuel in many reports. In this study, the effect of phosphorus concentration on lipid content was analyzed using the freshwater microalga Chlorella sp as a model. In addition, the carbohydrate and protein content were also analyzed in order to investigate the variations of biochemical composition under different phosphorus levels. Results showed that both lipid content and lipid productivity were increased under low phosphorus conditions. Furthermore, it was also found that lipid accumulation in cells decreased by supplementing the growth media with K2HPO4 in the late growth phase. The analysis of the total protein and the carbohydrate content showed that the former remained unaffected by external phosphorus variation; while the latter was directly correlated to phosphorus concentration. In summary, lipid accumulation had significant relationship with phosphorus concentration.
