Beschreibung
Zusammenfassung:	A single or plural stage process for the enzymatic delignification of lignocellulosic materials for use in the pulp and paper industry. Each stage comprises the step of incubating the lignocellulosic material with an effective amount of a ligninolytic enzyme preparation, in a reaction mixture comprising hydrogen peroxide at a low steady-state concentration. The ligninolytic enzyme preparation may comprise lignin peroxidases, Mn(II)-dependent peroxidases, or both these enzymes.
