expression cassette for eukaryotic cell transformation, process for eukaryotic cell transformation, genetically modified microorganism, biofuel and / or biochemical production process and biofuel and / or biochemical production thus produced

摘要

The present invention describes an expression cassette for transforming eukaryotic cells comprising the nucleotide sequence (sequence id: 2) encoding peptide with characteristic xylose isomerase (sequence id: 1), optionally also comprising other phosphate pathway genes. . The invention also describes genetically modified microorganism by inserting the described expression cassette capable of consuming xylose and converting ethanol as compared to its counterpart without said modifications. A process for producing biofuels and biochemicals, preferably ethanol, is also described from sugars abundant in the lignocellulosic portion of the plant biomass, mainly pentoses and, among the pentoses, mainly xylose. Also described are biofuels, preferably ethanol, and biochemicals produced by the process of the invention.
