Isolation and Screening of Lignin Degrading Fungi from Wood

Abstract

Abstract: Wood and lignocellulosic biomass is a low cost and abundant resource that can be used in the large scale production of fuels and chemicals. Lignocellulose can be converted into many products replacing products produced from fossil, such as bioenergy, biochemicals and biomaterial products through several treatment. In the bioethanol production, the lignin content in lignocellulose causes the conversion of cellulose to ethanol is less optimal. This research aimed to screen a number of fungal isolated from tropical forests to obtain the lignin-degrading fungi which are potentially used in lignocellulose biotreatment. The presences of covalent lignin carbohydrate linkage between sugar hydroxyl of hemicelluloses and phenylpropane subunits in lignin gives lignocellulose protection against degradation. Biofuel plays an essential role in replacing petroleum based fuels in current worldwide energy situation. The aim of the project is to identify new stain of fungi with high potential in degradation of lignin. The fungi is isolated from rotting wood piece for the study . Pereformed different methods to isolate the efficient fungi to degrade the lignin.
