Stress of Nutrients Deficiency on Growth and Lipid Accumulation in Oil-Rich Navicula sp.

Abstract:

Based on optimized aquatic diatom medium, treatment of nutrient deficiency was carried out to Navicula sp. and the analysis results of comprehensive biomass and total lipid content indicated that the optimal Tmass concentrations of TFeClB_3B·3HB_2BO,T TCdSOB_{4 B}and Citric acid were 1.2×10P^-5P mol/L, 0.8μg/L and 12 mg/L, respectively. Maximum biomass of Navicula sp. on this culture medium at 680 spectrophotometrically could reach 1.201. Final lipid content of this microalgae could be improved from 26.60% to 37.68% after the stress of nutrient deficiency treatment.
