摘要

Process for the use of distilled wine lees, with or without removal of tartaric acid, and economic nutritional supplement Debaryomyces hansenii yeast during the conversion of xylose to xylitol. The object of this invention is the formulation of an economic fermentative medium.; using lees vinification, a residue valueless and harmful to the environment, as a nutrient for formulating economic fermentation media and the natural production of food additives, as claimed xiltiol. Additionally it can recover the tartaric acid containing lees.; The bioconversion of xylose to xylitol by Debaryomyces hansenii, requires the input of expensive nutrients (yeast extract, peptone and malt extract), 30% increasing the final cost of xylitol obtained. These lees can be applied directly for a natural product, reducing process costs, and minimizing the environmental impact of this waste.
