Abstract
Described are compositions and methods relating to cellulase/hemicellulase enzyme blends for improving the enzymatic hydrolysis of cellulosic and hemicellulosic materials, as commonly found in biomass.

-14. (canceled)
A method for hydrolyzing a mixture of cellulosic and hemicellulosic materials, comprising contacting the mixture of cellulosic and hem icellulosic materials with:
- (a) a first enzyme composition comprising a cellulase,
- (b) a second enzyme composition comprising at least one xylanase selected from a GH10 or GH11 xylanase, and
- (c) a third enzyme composition comprising at least one additional hemicellulase that is not a GH10 or GH11 xylanase or not the same GH10 or GH11 xylanase as in (b),
- thereby hydrolyzing the mixture of cellulosic and hemicellulosic materials,
- wherein the contacting results in at least one of (i) enhanced glucan conversion or (ii) enhanced xylan conversion compared to equivalent contacting in the absence of the at least one additional hemicellulase.
