Screening of Factors Affecting Biological Delignification Process of Oil Palm Trunk Using Local Oyster Mushroom (Pleurotus Ostretus)

Oil palm trunk, a lignocellulosic waste, contains high cellulose content. The removal of lignin is essential as lignin inhibits almost all reactions occur on cellulose. This study is about the usage of a local oyster mushroom (Pleurotus ostreatus) as an agent of delignification and the screening of...
