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...

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 production of bioethanol.Currently known delignification method includes physical,chemical,and biological method.The biological method or biodelignification is known as a method that uses less energy and consume fewer chemicals that lead it to become the only method with environmental and cost friendly approach. Therefore, this research are conducted to study the factors that affect the biodelignification of oil palm trunk and to screen the factor that has significant effect on biodelignification of oil palm trunk using Pleurotus ostreatus. The effect of temperature,pH, humidity,light exposure,moisture content,fungi to medium ratio,and contact time on biodelignification process of oil palm trunk will be studied in this research.The oil palm trunk was incubated with the Pleurotus ostreatus in a temperature controlled incubator for a predetermined period of time.It was later cleaned after the incubation period ends and dried.The dried oil palm trunk was then analysed using the Klason-Lignin determination method where the lignin percentage in the oil palm trunk sample was obtained.
