  • Patent number: 11453884
    Abstract: A method is provided for producing modified mutant yeast and the resulting yeast that can be used as a platform for terpene production. The method includes chemical mutagenesis to effect ergosterol dependent growth in yeast. Subsequently, these yeast are subjected to an erg9 knockout mutation to thereby produce ergosterol dependent growth/erg9 knockout mutation yeast cell lines. The resulting yeast are well suited for use in the production of terpenes.

  • Patent number: 8017835
    Abstract: The present invention relates to transformed plants with an altered terpene content, preferably over-accumulating a mono- or sesqui-terpene. By transformation of plants with genes encoding terpene synthases (TS), and prenyl transferases (PRT), plants accumulating at least 1000 ng/per g of fresh leaf of a specific terpene were obtained. The present invention provides an advantageous system for production of terpenes in that any desired mono- or sesqui-terpene at the choice of the skilled person can be produced in plants. Preferably, the transformed plants contain at least one recombinant plastid targeted TS and PRT.
