Abstract

The production of chemicals and fuels from lignocellulosic biomass has great potential industrial applications due to its economic feasibility and environmental attractiveness. However, the utilized microorganisms must be able to use all the sugars present in lignocellulosic hydrolysates, especially xylose, the second most plentiful monosaccharide on earth. Yarrowia lipolytica is a good candidate for producing various valuable products from biomass, but this yeast is unable to catabolize xylose efficiently. The development of metabolic engineering facilitated the application of Y. lipolytica as a platform for the bioconversion of xylose into various value-added products. Here, we reviewed the research progress on natural xylose-utilization pathways and their reconstruction in Y. lipolytica. The progress and emerging trends in metabolic engineering of Y. lipolytica for producing chemicals and fuels are further introduced. Finally, challenges and future perspectives of using lignocellulosic hydrolysate as substrate for Y. lipolytica are discussed.
