| Abstract | ||||
| The algal physiological and biochemical constituents including fatty acid synthesis can be improved by salinity stress. Also, organic carbon sources particularly glucose stimulates efficiently the biomass and lipid accumulation in microalgae. This study aimed to investigate the effect of different concentrations of sodium chloride or glucose on growth performance and lipid accumulation of Monoraphidium braunii. M. braunii was grown on Bold’s Basal medium with 0.0, 0.5, 1.0 and 2.0 g L-1 NaCl or 0.0, 1.25, 2.5, and 5.0 g L-1 glucose. The results revealed an increment in the growth in terms of dry weight (0.5 g L-1) and lipid production (40% DW) at 2.5 g L-1 glucose more than those grown at 0.5 g L-1 NaCl which they recorded 0.35 g L-1 and 22.5% DW, respectively. Therefore, the results specify NaCl at a certain extent or adequate concentration of glucose as an organic carbon source to improve M. braunii lipid production. | ||||
