Abstract
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.
