AbstractBiodiesel is an excellent renewable energy carrier currently being produced from vegetable oil. However, large-scale biodiesel production remains challenge because of limited supply of oil plant-based products. On the other hand, carbohydrate form lignocellulosic biomass is the most abundant renewable resources. In this context, it is pivotal to convert carbohydrates into products with similar properties to conventional fossil fuel. Oleaginous yeasts exhibit a capacity of assimilating carbohydrates to accumulate intracellular lipid composed of C16 and C18 series long-chain fatty acids. During the past few years, we have been working on biodiesel production using lignocellulosic feedstock, which included three steps, 1) Hydrolysis of lignocellulose to carbohydrate; 2) Lipid production with oleaginous yeasts; and 3) Transesterification of microbial lipid to biodiesel. We identified a hand of outstanding oleaginous yeasts [1], including R. toruloides, L. starkeyi, and C. curvatus. These yeasts use materials including glucose, xylose, raw glycerol and corn stalk hydrolysates. We optimized lipid production processes [2]. When using the yeast R. toruloides as the lipid producer in a 15-L bioreactor, we achieved lipid content, production titer and lipid productivity of over 65 wt%, 100 g/L and 0.8 g/l/h, respectively. We also showed that biodiesel can be produced using either the oleaginous microbial biomass or the microbial lipid as the feedstock [3]. Taken together, we demonstrated that biodiesel can be produced from microbial lipid, which in turn, can be obtained by fermentation of biomass-derived carbohydrates using oleaginous microorganisms.; Biodiesel is an excellent renewable energy carrier currently being produced from vegetable oil.
