Papermaking fibers are treated with certain hydrolytic enzymes, specifically including cellulases, such as truncated endo-glucanases, which have been freed of their cellulose binding domain, to generate aldehyde groups at or near the surface of the fibers. Paper sheets made from the resulting fibers exhibit improved strength characteristics relative to paper sheets made from untreated fibers.

Papierherstellungfasern werden mit bestimmten hydrolytischen Enzymen, spezifisch einschließlich Zellulasen, wie beschnittene endo-glucanases, die von ihrem verbindlichen Gebiet der Zellulose freigegeben worden sind behandelt, um Aldehydegruppen oder nahe an der Oberfläche der Fasern zu erzeugen. Die Papierblätter, die von der resultierenden Faserausstellung gebildet wurden, verbesserten Stärke Eigenschaften die relative.to Papierblätter, die von unbehandelten Fasern gebildet wurden.
