| Abstract | Our study was focused on optimum physical and nutritional conditions in lipid accumulation of microalgae (Nostoc sp.) from Bueng Boraphet using BG-11 as cultured media. Results showed that the optimum temperature and acid-base value were at 30 oC and pH 7.0, respectively under autotrophic condition. Nostoc sp. was able to properly grow and gave 0.517 g/L dry cell weight and 4.16% lipid content. The optimum nutrition for lipid accumulation by Nostoc sp. was then examined. These conditions were found to be 0.15% potassium nitrate (KNO3), 10% glucose and 0.004% dipotassium phosphate (K2HPO4) at 30 oC, pH 7.0 under mixotrophic condition. Nostoc sp. showed the highest dry cell weight and lipid content at 1.314 g/L and 4.48 percent respectively. The trend of lipid accumulation was depend on the growth rate of Nostoc sp. |
