The present invention describes a process for at least a 90% conversion of a plant biomass preferably by a reduction of the units of cellulase needed and by using a xylanase which acts synergistically with the cellulase to improve the yield of xylose and glucose as sugars. The process enables greater conversion of a lignocellulosic plant biomass to glucose and xylose for use as animal feeds and as fermentation as medium for producing ethanol.
