摘要： The invention relates to the production of biofuels, proteins, peptides and other value-added compounds from crude carbon sources. The inventors identified genes encoding novel pentose transporters, in particular transporters of L-arabinose and/or D-xylose. Regulation of the Aspergillus niger genes by xlnR and araR was instrumental in the identification of these genes and their substrate specificities. Provided are novel pentose transporters and their encoding nucleic acids. Also provided are host cells (over)expressing a transporter, and industrial applications thereof, for instance in biofuel production.
