A method for the production of xylitol from an aqueous xylose solution which comprises the steps of fermenting said aqueous xylose solution with a yeast strain capable of converting free xylose to xylitol, and free hexoses present in said solution to ethanol, for a period of time sufficient to produce a fermented solution containing xylitol; and separating one or several xylitol-rich fraction by chromatographic separation from said fermenting solution.
Méthode de production de xylitol à partir d'une solution aqueuse de xylose comprenant les étapes suivantes: fermentation de ladite solution aqueuse de xylose avec une souche de levure capable de convertir le xylose libre en xylitol, et des hexoses libres présents dans ladite solution en éthanol, pendant une période de temps suffisante pour obtenir une solution fermentée contenant du xylitol; et séparation d'une ou plusieurs fractions riches en xylitol par séparation chromatique de ladite solution de fermentation.
