Screening of factors for biodelignification of oil palm trunk using pleurotus ostreatus

Delignification of lignocellulosic material is a crucial part in most research where it needs to be done to ensure the lignin compound are removed from the hemicelluloses and celluloses contained in the material.Unbound hemicelluloses and celluloses can be used further in application such as product...
