  • Recombinant DNA encoding neutral trehalase
    Patent number: 5312909
    Abstract: 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.
    Type: Grant
    Filed: March 22, 1991
    Date of Patent: May 17, 1994
    Assignee: Gist Brocades, N.V.
    Inventors: Marianne Driessen, Klaas A. Osinga, Margareta A. Herweijer
  • Saccharomyces strains for maltose fermentation
    Patent number: 5190877
    Abstract: Methods and compositions are provided relating to yeasts capable of improved fermentation of sugars. Particularly, genes from the MAL locus are used for transformation of yeast hosts, where the genes are under the wild-type promoter or a strong promoter which provides for regulatable or constitive expression under the conditions of fermentation. Particularly, the yeast hosts find use in the leavening of dough.
