NOVELTY - A modified Saccharomyces cerevisiae cell that differs from an unmodified cell is new. The modified S.cerevisiae cell comprises bifunctional alcohol/aldehyde dehydrogenase (adhE) polypeptide having at least 50% sequence identity with respect to an amino acid sequence of SEQ ID NO: 1 and has increased expression of an acetyl-coenzyme A (CoA) synthetase isoform 2 (ACS2) polypeptide. Sequence not defined here may be found at ftp://ftp.wipo.int/pub/published_pct_sequences/publication.    USE - The modified S.cerevisiae cell is useful for producing ethanol from acetyl-CoA (claimed). The produced ethanol is used for producing biofuel.    ADVANTAGE - The modified S.cerevisiae cell enables to produce ethanol with increased yield of 40%.    DETAILED DESCRIPTION - A modified Saccharomyces cerevisiae cell that differs from an unmodified cell is new. The modified S.cerevisiae cell comprises bifunctional alcohol/aldehyde dehydrogenase (adhE) polypeptide having at least 50% sequence identity with respect to an amino acid sequence of SEQ ID NO: 1 and has increased expression of an acetyl-coenzyme A (CoA) synthetase isoform 2 (ACS2) polypeptide having at least 50% sequence identity with respect to an amino acid sequence of SEQ ID NO: 2, where the ACS2 polypeptide is capable of catalyzing the conversion of acetate to acetyl CoA, and the unmodified cell is not sake yeast strain. The adhE polypeptide is capable of catalyzing formation of ethanol from acetyl coenzyme A (CoA). INDEPENDENT CLAIMS are included for the following: (1) method for improving ability of yeast cell to grow on a solid medium, or in a liquid medium comprising at least 50 mM acetate, involves introducing to the yeast cell an adhE polypeptide having at least 50% sequence identity with respect to an amino acid sequence of SEQ ID NO: 1, where the adhE polypeptide is capable of catalyzing the formation of ethanol from acetyl CoA; and (2) method for increasing ethanol yield from a yeast cell, involves expressing in the yeast cell an adhE polypeptide having at least 50% sequence identity to the amino acid sequence of SEQ ID NO: 1, and culturing the cell in a medium comprising glucose.
