Abstract
Described herein are recombinant fermenting organisms having a heterologous polynucleotide encoding an alpha-amylase and/or a heterologous polynucleotide encoding a trehalase. Also described are processes for producing a fermentation product, such as ethanol, from starch or cellulosic-containing material with the recombinant fermenting organisms.
Claims20
A method of producing a fermentation product from a starch-containing or cellulosic-containing material comprising:
- (a) saccharifying the starch-containing or cellulosic-containing material;
- and
- (b) fermenting the saccharified material of step (a) with a recombinant yeast cell;
- wherein the recombinant yeast cell comprises a heterologous polynucleotide encoding an alpha-amylase having a mature polypeptide sequence with at least 95% sequence identity to the amino acid sequence of SEQ ID NO:
- 126.
A recombinant yeast cell comprising a heterologous polynucleotide encoding an alpha-amylase having a mature polypeptide sequence with at least 95% sequence identity to the amino acid sequence of SEQ ID NO:
- 126.
