  • High eicosapentaenoic acid producing strains of Yarrowia lipolytica
    Publication number: 20060115881
    Abstract: Engineered strains of the oleaginous yeast Yarrowia lipolytica capable of producing greater than 25% eicosapentaenoic acid (EPA, an ?-3 polyunsaturated fatty acid) in the total oil fraction are described. These strains comprise various chimeric genes expressing heterologous desaturases, elongases and acyltransferases and optionally comprise various native desaturase and acyltransferase knockouts to enable synthesis and high accumulation of EPA. Production host cells are claimed, as are methods for producing EPA within said host cells.

  • Docosahexaenoic acid producing strains of Yarrowia lipolytica
    Publication number: 20060110806
    Abstract: An engineered strain of the oleaginous yeast Yarrowia lipolytica capable of producing greater than 5.6% docosahexaenoic acid acid (DHA, an w-3 polyunsaturated fatty acid) in the total oil fraction is described. This strain comprises various chimeric genes expressing heterologous desaturases, elongases and acyltransferases and optionally comprises various native desaturase and acyltransferase knockouts to enable synthesis and high accumulation of DHA. Production host cells are claimed, as are methods for producing DHA within said host cells.

  • High arachidonic acid producing strains of Yarrowia lipolytica
    Publication number: 20060094092
    Abstract: Engineered strains of the oleaginous yeast Yarrowia lipolytica capable of producing greater than 10% arachidonic acid (ARA, an ?-6 polyunsaturated fatty acid) in the total oil fraction are described. These strains comprise various chimeric genes expressing heterologous desaturases, elongases and acyltransferases, and optionally comprise various native desaturase and acyltransferase knockouts to enable synthesis and high accumulation of ARA. Production host cells are claimed, as are methods for producing ARA within said host cells.
