YEAST STRAINS WITH ENHANCED TREHALOSE CONTENT, PROCESS TO OBTAIN SUCH YEASTS AND THE USE OF THESE YEASTS

摘要

NEW YEAST STRAINS WITH ENHANCED TREHALOSE CONTENT, PROCESS TO OBTAIN SUCH YEASTS AND THE USE OF THESE YEASTS. A transformed yeast is disclosed, comprising at least one gene encoding neutral trehalase or trehalose-6-phosphate synthase which gene has been modified such that it differs from a corresponding wild-type gene encoding neutral trehalase or trehalose-6-phosphate synthase, the yeast having as a result a different trehalose content from the untransformed parent yeast. The sugar resistance and drying resistance of the yeast compared to those of the untransformed strain are thereby improved.
