Abstract
The technical field of preparation of organic compounds, and particularly to yeasts producing tyrosol or hydroxytyrosol and construction methods thereof. PcAAS and ADH-encoding DNA sequences are introduced into the yeast strain BY4741, to obtain a PcAAS-ADH recombinant yeast producing tyrosol. A PDC1 knockout cassette and a TyrA expression cassette are introduced into the PcAAS-ADH recombinant yeast to obtain a PcAAS-ADH-ΔPDC1-TyrA recombinant yeast producing tyrosol. A HpaBC encoding DNA sequence is introduced into the PcAAS-ADH-ΔPDC1-TyrA recombinant yeast, to obtain a PcAAS-ADH-HpaBC-ΔPDC1-TyrA recombinant yeast producing hydroxytyrosol. The construction of a tyrosol or hydroxytyrosol biosynthesis pathway in the yeast strain BY4741 enhances the production of tyrosol or hydroxytyrosol.
