This study focuses on the production of biolipids by fermentation of the yeast Saccharomyces cerevisiae ATCC 9763 on a hydrolysate of the lignocellulosic biomass of Ampelodesmos mauritanicus (Diss). The central composite design (CCD) experimental plan was used to optimize biolipids production under the following experimental conditions: the concentration of dry yeast which varied from 3 to 12 g/L, the concentration of reducing sugars in the hydrolysate (glucose equivalent) was between 6 and 20 g/L, the C/N ratio varied from 40 to 180, and the fermentation time varied from 8 to 24 h. The optimal biolipid results were 49% obtained under conditions of 3 g/L of yeast concentration, 20 g/L of glucose concentration, 180 of C/N ratio, and 24 h of fermentation time. Biolipids were characterized by gas chromatography coupled with mass spectrometry (CG/MS) and the lipid profile revealed that palmitic fatty acid is the major component produced by yeast at a level of 48.49% followed by stearic fatty acid with a level of 43.65%; this fatty acid composition is similar to that of some vegetable oils. The promising potential of lignocellulosic biomass as a fermentation medium for Saccharomyces cerevisiae ATCC 9763 to produce fatty acids and other value-added compounds has been demonstrated and the produced biolipids are a promising feedstock for biodiesel.
