Abstract
A method of producing hardwood pulp is provided. This method comprises treating hardwood chips with one or more than one Family 11 xylanase enzyme in the absence of adding an oxidizing enzyme for about 5 minutes to about 120 minutes, to produce a treated chip mixture. The treated chip mixture is then mechanically refined to produce the hardwood pulp.
