Beschreibung
Zusammenfassung:	A plural stage process for the enzymatic delignification of lignocellulosic materials for use in the pulp and paper industry comprising one or more ligninolytic enzyme treatment stages ard one or more xylanase treatment stages. The ligninolytic enzyme preparation may comprise lignin peroxidases, Mn(II)-dependent peroxidases, or both these enzymes.
