DNA sequence encoding a specific l-arabinose transporter, A cDNA molecule, a plasmid comprising the said DNA sequence, host cell transformed with such plasmid and application thereof

The present invention refers to host cells genetically modified microorganisms by introducing a nucleic acid sequence encoding a specific L-arabinose transporter from yeast. The host cells are preferably those of an eukaryotic microorganism such as yeasts or filamentous fungi. The invention is useful for the complete use of sugar obtained from plant biomass and other ligno-cellulose materials of biotechnological importance in the production of biofuels, bulk and platform chemicals including ethanol, butanol, lactate, 1,4-diacids (succinate, fumaric, malic), glycerol, sorbitol, mannitol, xylitol/arabinitol, L-ascorbic acid, xylitol, hydrogen gas, 2,5-furan dicarboxylic acid, 3-hydroxy propionic acid, aspartic acid, glutaric acid, glutamic acid, itaconic acid, levulinic acid, and 3-hydroxybutyrolactone, fatty acids, fatty-derived molecules, isoprenoids, isoprenoid-derived molecules, alkanes, isopentanol, isoamylacetate, using genetically-modified microorganisms to consume and ferment L-arabinose in hexose and pentose mixtures resulting from renewable raw materials.
