چکیده انگلیسی
Chlorella sp. (FACHB-1748) was cultivated outdoors under natural sunlight to evaluate its potential for biofuel production. Urea was selected as nitrogen source, and the concentration was optimized. When the culture reached the late exponential stage, a triggering lipid accumulation test was conducted using different concentrations of sodium chloride and acetate. A scaling-up experiment was also conducted in a 70Â L photobioreactor. The highest biomass productivity (222.42, 154.48Â mg/L/d) and lipid productivity (64.30, 33.69Â mg/L/d) were obtained with 0.1Â g/L urea in 5 and 70Â L bioreactors, respectively. The highest lipid content (43.25%) and lipid yield (1243.98Â mg/L) were acquired with the combination of 10Â g/L sodium chloride and acetate. Moreover, the qualities of biodiesel, cetane number, saponification value, iodine value, and cold filter plugging point complied with the standards set by the National Petroleum Agency (ANP255), Standard ASTMD6751, and European Standard (EN 14214).
