Abstract
The present invention provides fungal xylanase and/or beta-xylosidase enzymes suitable for use in saccharification reactions. The present application further provides genetically modified fungal organisms that produce xylanase and/or beta-xylosidases, as well as enzyme mixtures exhibiting enhanced hydrolysis of cellulosic material to fermentable sugars, enzyme mixtures produced by the genetically modified fungal organisms, and methods for producing fermentable sugars from cellulose using such enzyme mixtures.
