FIELD: biotechnology. ^ SUBSTANCE: invention relates to biotechnology, more specifically to use of transformed cells Saccharomyces cerevisiae, which belong to a strain used in wine making, capable of high urea degradation in conditions of fermentation of grape juice, compared untransformed cells of the said strain. The cell is transformed by recombinant nucleic acid, which contains a sequence, which includes an open reading frame, homologic open reading frame DUR1,2 and a coding protein, with urea-degrading fermentation activity, and a promoter, suitable for mediating expression of a protein with urea-degrading fermentation activity, in conditions of fermentation of grape juice. ^ EFFECT: invention allows for obtaining wine, which cannot be distinguished from its organoleptic properties from wine obtained using untransformed cells. ^ 13 cl, 7 dwg, 1 tbl, 1 ex |
