Abstract

L'invention concerne un procédé pour l'élimination de la lignine dans des produits lignocellulosiques et/ou pour le blanchiment de produits lignocellulosiques pour le désencrage enzymatique des vieux papiers et pour le traitement des eaux résiduaires dans la fabrication du papier et de la cellulose, dans lequel on utilise des laccases obtenues à partir de coriolus versicolor et d'autres générateurs de laccases, avec addition et/ou addition dosée simultanées d'agents réducteurs et oxydants non aromatiques, ainsi que de composés phénoliques et/ou de composés aromatiques non phénoliques qui, ou bien oxydent les structures phénoliques et non phénoliques de la lignine, directement sous l'effet de ces composés aromatiques phénoliques et/ou non phénoliques, ou bien oxydent la lignine par oxydation intermédiaire par ces composés, d'autres composés phénoliques et/ou non phénoliques.
