Sustainable and economically viable manufacturing of bioethanol from lignocellulose raw material is dependent on the availability of a robust ethanol producing microorganism， able to ferment all sugars present in the feedstock， including the pentose sugars L-arabinose and D-xylose. Saccharomyces cerevisiae is a robust ethanol producer， but needs to be engineered to achieve pentose sugar fermentation.
