Abstract:
The main challenge of producing biodiesel from renewable lignocellulosic biomass through hydrolysis and fermentation is overcoming the cost-limiting factors associated with various stages of this technology. In the present research, Sorghum and Giant Reed has been studied as a nutrient for the Lipomyces starkeyi, oleaginous yeast. Lignocellulosic materials was hydrolyzed with H2SO4 5% to obtain maximum amount of reducing sugar. The microbial growth was performed at various concentrations (100%, 50% and 25%) of cellulosic hydrolysate, to characterize both the lipid yield and the efficiency of the biomass conversion. Dilute acid-hydrolysis was favorable condition of pretreatment process and microbial growth was significantly increased when the feedstock (hydrolysate) was preliminary diluted. Since Lipomyces starkeyi was able to grow in the hydrolysate without adding any commercial nutrient, further study is going on to optimize the hydrolysis and fermentation process to utilize the maximum portion of lignocellulosic biomass.
