FIELD: genetic engineering, microbiological industry, biotechnology. SUBSTANCE: yeasts or fungi producing arabitol are transformed with DNA encoding D-arabitol dehydrogenase forming D-xylose and DNA encoding xylitol dehydrogenase. Then transformed yeasts or fungi are cultured under conditions providing the synthesis of xylitol and xylitol is isolated. Yeasts are taken among Zygosaccharomyces rouxii, Candida polymorpha, Torulopsis candida, Pichia farinosa, Torulaspora hansenii. Fungi are taken among Dendryphiella salina and Schizophyllum commune. Method ensures to convert easily available carbon sources, for example, D-glucose to xylitol. EFFECT: improved method of producing. 21 cl, 13 dwg, 7 tbl, 15 ex
