Abstract
The present invention relates to the use of nucleic acid molecules coding for a bacterial xylose isomerase (XI), preferably coming from, for reaction/metabolization, particularly fermentation, of recombinant microorganisms of biomaterial containing xylose, and particularly for the production of bioalcohols, particularly bioethanol, by means of xylose fermenting yeasts. The present invention further relates to cells, particularly eukaryotic cells, which are transformed utilizing a nucleic acid expression construct which codes for a xylose isomerase, wherein the expression of the nucleic acid expression construct imparts to the cells the capability to directly isomerize xylose into xylulose. Said cells are preferably utilized for reaction/metabolization, particularly fermentation, of biomaterial containing xylose, and particularly for the production of bioalcohols, particularly bioethanol. The present invention also relates to methods for the production of bioethanol, and to methods for the production of further metabolization products, comprising the metabolization of media containing xylose.
