two chemical bleached pulps were treated with a crude enzyme mixture in the presence of hgcl//2 (1 mm). such treatment inhibited endo-cellulases. xylans were thus subjected to selective in-situ hydrolysis. the enzyme-treated pulps can be compared to slightly beaten pulps. the modified fibers show external fibrillation and reveal strong beatability. therefore, a decrease in energy demand can be gained in the papermaking process. a reduction of fiber intrinsic strength is, however, observed mainly due to the hydrolysis of xylan macromolecules which confirms their important role in fiber wall cohesion.
