NOVELTY - Treating biomass to be supplied to a fermentation system for production of a fermentation product comprises: pre-treating the biomass into pre-treated biomass; separating the pre-treated biomass into a first component comprising glucan and a second component comprising sugars; providing a combined component comprising at least a portion of the first component and at least a portion of the second component; treating the combined component of the pre-treated biomass into a treated component comprising glucose by application of an enzyme formulation.    USE - The method and the system are useful for treating biomass (comprising lignocellulosic material, which consists essentially of corn cobs, corn plant husks, corn plant leaves, and corn stalks) to be supplied to a fermentation system for production of a fermentation product (all claimed). The method is useful for treating biomass in the production of ethanol.    ADVANTAGE - The method and the system improves the efficiency and yield of cellulosic ethanol form biomass.    DETAILED DESCRIPTION - Treating biomass to be supplied to a fermentation system for production of a fermentation product comprises: pre-treating the biomass into pre-treated biomass; separating the pre-treated biomass into a first component comprising glucan and a second component comprising sugars; providing a combined component comprising at least a portion of the first component and at least a portion of the second component; treating the combined component of the pre-treated biomass into a treated component comprising glucose by application of an enzyme formulation, where the treated component comprises 2-15 wt.% glucose; and the biomass comprises lignocellulosic material comprising at least one of corn cobs, corn plant husks, corn plant leaves, and corn plant stalks. An INDEPENDENT CLAIM is included for a system for treating biomass to be supplied to a fermentation system for production of a fermentation product comprising: an apparatus (600) configured to pre-treat the biomass into pre-treated biomass; a separator (606) configured to separate the pre-treated biomass into a first component comprising glucan and a second component comprising sugars; a vessel configured to contain a combined component comprising at least a portion of the first component and at least a portion of the second component and to be supplied with an enzyme formulation so that a treated component comprising glucose can be created by enzyme hydrolysis of the combined component; where the biomass comprises lignocellulosic material; and the lignocellulosic material comprises at least one of corn cobs, corn plant husks, corn plant leaves, and corn plant stalks.    DESCRIPTION OF DRAWING(S) - The figure shows a perspective view of an apparatus used to pre-treat and separate the biomass.    Apparatus for pre-treat and separate the biomass (600)    Grinder (602)    Reaction vessel (604)    Separator. (606)
