Patent ID: 8541213

Claim:
A method of production of saturated branched alcohol, comprising: culturing in culture medium a recombinant yeast in which the HMG1 gene of Saccharomyces cerevisiae has been expressed to a high degree and the ADP-ribose pyrophosphatase gene and/or the yhfR gene are introduced so as to be expressed therein, wherein the ADP-ribose pyrophosphatase gene encodes a protein having the amino acid sequence of SEQ ID NO: 2 or a protein having an amino acid sequence with a 90% or more similarity to the amino acid sequence of SEQ ID NO: 2, and wherein the yhfR gene encodes a protein having the amino acid sequence of SEQ ID NO: 4 or a protein having an amino acid sequence with a 90% or more similarity to the amino acid sequence of SEQ ID NO: 4; and collecting the branched alcohol from the medium.
