Metabolic engineering of xylose fermenting eukaryotic cells

The present invention relates to further genetic modifications in eukaryotic host cells that have been transformed to express a xylose isomerase that confers the host cell the ability of isomerising xylose to xylulose. The further genetic modifications are aimed at improving the efficiency of xylose metabolism and include e.g. reduction of...

Method for producing ethanol from xylose-containing substance
