  • Publication number: 20190376104
    Abstract: The present invention provides a method, of producing a useful substance, including secreting and producing a useful substance in broth by yeast contained in the broth, the yeast being a Saccharomyces strain, the broth containing a compound (A) represented by a formula (1), the compound (A) having an HLB value of 0.1 to 16 and a number average molecular weight of 200 to 30000, the weight percentage of the compound (A) based on the weight of the broth being 0.0001 to 10 wt %: HO—(A1O)m1-(A2O)m2-(A3O) m3—H ??(1) wherein A1O, A2O, and A3O each independently represent a C2-C4 oxyalkylene group; A1O and A2O have different structural formulas, A2O and A3O have different structural formulas; and m1, m2, and m3 each respectively represent the average number of moles of A1O, A2O, and A3O added, and are each independently a number in the range of 1 to 600.

  • Publication number: 20170211063
    Abstract: The object of the present invention is to provide a production system that is capable of high-level secretory production of a protein (and in particular, a protein with a complicated structure such as a structure with S—S bonds) in a host cell such as yeast and is suitable for industrial production with high safety that does not require explosion-proof facilities. The present invention provides a transformed yeast into which a chaperone gene has been introduced and in which the aox1 gene and/or the protease gene have been disrupted and a method for producing a protein involving the use of such transformed yeast.
