<i>Trichoderma reesei </i>α-amylase enhances saccharification of corn starch |
摘要 |
A maltogenic α-amylase from Trichoderma reesei (TrAA) and variants thereof in the presence of a glucoamylase are useful in the production of high-glucose syrups from liquefied starch, where the high-glucose syrups produced thereby contain at least about 97% glucose. In this process, TrAA advantageously suppresses the reversion of glucose to malto-oligosaccharides. Expression hosts and encoding nucleic acids useful for producing TrAA and its variants also are provided. |

1. A method of baking, comprising adding an isolated polypeptide comprising (i) residues 21-463 of SEQ ID NO:3, or (ii) a variant of Trichoderma reesei α-amylase (TrAA), wherein the variant has α-amylase activity and at least 90% amino acid sequence identity to residues 21-463 of SEQ ID NO:3 to a substance to be baked, and baking the substance. |
