A method to increase ethanol production from a corn dry-mill process is described that comprises adding an enzyme preparation derived fromhaving 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

Cellulolytic enzyme enhancement of dry grind corn processing and ethanol production

Novel fiber processing methods and the products obtained therefrom are disclosed. Methods may include thermochemical and/or enzymatic hydrolysis of fiber feedstocks including distillers' dried grains, distillers' dried grains with solubles, soyhull, miscanthus and switchgrass. Enzymatic hydrolysis includes hydrolysis with cellulase, hemicellulase, and protease.
