Xylose isomerases that confer efficient xylose fermentation capability to yeast

The present invention relates to novel nucleic acid sequences encoding bacterial xylose isomerases that upon transformation of a eukaryotic microbial host cell, such as yeast, to confer to the host cell the ability of isomerising xylose to xylulose. Thenucleic acid sequences encode xylose isomerases that originate from bacteria such as Eubacterium sp., Clostridiumcellulosiand others. The invention further relates to fermentation processes wherein the transformed host cells ferment a xylose-containing medium to produce ethanol or other fermentation products.
