Zusammenfassung:	A process for producing biofuel from biomass that includes free monosaccharides is provided. The process comprises the steps of mixing the biomass with a recycled hydrolysate for a sufficient time to elute a portion of the free monosaccharides from the biomass thereby forming a sugar enriched hydrolysate. Sugar enriched hydrolysate is then separated from the biomass and monosaccharides contained in the separated sugar enriched hydrolysate are fermented. L'invention concerne un procédé de production de biocarburant à partir de biomasse qui inclut des monosaccharides libres. Le procédé comprend les étapes de mélange de la biomasse et d'un hydrolysat recyclé pendant un temps suffisant pour éluer une partie des monosaccharides libres provenant de la biomasse, formant ainsi un hydrolysat enrichi en sucre. L'hydrolysat enrichi en sucre est ensuite séparé de la biomasse et les monosaccharides contenus dans l'hydrolysat enrichi en sucre séparé sont fermentés.
