چکیده انگلیسی
In order to evaluate the efficiency and potential of salt addition-based two-stage cultivation technology, on the basis of urea as nitrogen source, we compared four types of salts (NaCl, NaHCO3, NaS2O3 and NaAc) as inducers for lipid production in Desmodesmus abundans. The maximum biomass productivity (270.08 mg Lâ1 dâ1) was obtained by using 0.25 g Lâ1 urea. The highest lipid productivity (67.08 mg Lâ1 dâ1) and better biodiesel quality were realized by addition of 20 g Lâ1 NaCl, and the optimal time point for salt addition was determined at 1.79 g Lâ1 of biomass density. Further cost analysis demonstrated this cultivation process was relatively economical. Above results suggest that NaCl addition is an economical and applicable strategy for lipid enhancement and can be extended for microalgae-based biodiesel production.
