摘要

Enzymes can be applied for the deinkign of wastepaper for the recovery of secondary fibers.Mainly cellulases and hemicellulases have bene utilized for the deinkign of different types of newsprint and office waste papers.Ink removal efficiencies and brightness gains have been reported in several cases to be equal or superior to conventional chemical deinkign procedures.paper printed with vegetable oil based inks could be deinked efficiently in a deinkign procedure cincluding a nertral ddeinkign chemical in combinaiton with lipase,cellulase and xylanase.
