The present invention concerns a method of producing glucose from a granular starch substrate comprising, contacting a slurry comprising granular starch obtained from plant material with an alpha-amylase at a temperature below the starch gelatinization temperature of the granular starch to produce oligosaccharides and hydrolyzing the oligosaccharides to produce a mash comprising at least 20% glucose and further comprising fermenting the mash to obtain ethanol.
La présente invention concerne un procédé de production de glucose à partir d'un substrat d'amidon granulaire comprenant la mise en contact d'une suspension dense comprenant de l'amidon granulaire obtenu à partir de matériau de plante avec une alpha-amylase à une température au-dessous de la température de gélatinisation d'amidon de l'amidon granulaire pour produire des oligosaccharides et hydrolyser les oligosaccharides pour produire une pâte comprenant au moins 20 % de glucose et comprenant en outre la fermentation de la pâte pour obtenir de l'éthanol.
