A biopulping fungus in compression-baled, nonsterile green pine chips enhancing kraft and refiner pulping

The present study indicated that inoculation of compression-baled, nonsteri le jack pine chips with Ceriporiopsis subvermispora led to a 20% reduction in the total kraft pulping time necessary for achieving pulp and paper prop erties comparable to those from controls. The resulting pulp from the contr ol and C. subvermispora-treated chips responded to hydrogen peroxide bleach ing similarly; the final brightness values were statistically identical, al though the biokraft pulps consumed less hydrogen peroxide. Refiner pulps fr om these baled chips led to significant increases in paper burst, tensile, and tear strength.
