Abstract
A method to increase ethanol production from a corn dry-mill process is described that comprises adding an enzyme preparation derived from Trichoderma reesei having cellulolytic activity to a saccharification process that includes conventional alpha amylase and glucoamylase. The addition of the cellulolytic enzyme decreases viscosity of the saccharified mash and can increase ethanol yield from a dry grind fermentation by as much as 10% or more. Specific characteristics are provided to show surprising and advantageous results of one particular preparation of cellulolytic enzymes from T. reesei.
