| Abstract: | Under batch culture condition, the effect of different nitrogen (NaNO3 ,glutamic acid,urea and ammonium sulfate), phosphorus and carbon sources on the fatty acid composition in Spirulina platensis was carried out. Results showed that the algal could synthesize linolenic acid and TPUFA contents raise a peak value when the concentration of NaNO3, K2HPO4 and NaHCO3 was 0.5,0.3～0.5 and 4.5g/dm3 respectively. Result also indicated that taking glutamic acid, urea and ammonium sulfate as nitrogen source, the algal contains C18:3 and TPUFA contents increases 6.43% ,4.46% and 7.28%, respectively. In addition, taking glutamic acid as nitrogen source, the algal also could synthesize linolenic acid. |
