Abstract
A method of making a wood pulp is disclosed. Wood is first chipped into wood chips. The wood chips are treated with an amount of sulfite salt sufficient to inhibit indigenous microorganism growth. The treated wood chips are introduced into a bioreactor and inoculated with a culture of white-rot fungus. The wood chips are incubated under conditions favoring the propagation of white-rot fungus and then mechanically pulped.
