Title: A-xylosidase enhanced conversion of plant biomass into fermentable sugars

Abstract

The invention relates to increasing the availability of fermentable sugars from plant biomass, such as glucose and xylose. As described herein, .alpha.-xylosidases can be employed with cellulases to enhance biomass conversion into free, fermentable sugar residues.
