Abstract: Efficient enzymatic conversion of renewable biomass becomes the focus of intensive research currently throughout the world. Lignocellulose is comprised mainly of cellulose, hemicelluloses and lignin. Removal of lignin from the complex lignocellulosic matrix is considered as the key process of comprehensive lignocellulose utilization, which renders recalcitrant lignocellulosic biomass more accessible to the hydrolytic enzyme system. Biodegradation of lignin by fungi is more environment friendly and less energy intensive, compared to other pretreatment methods. Its mechanism is based principally on the activity of different extracellular enzymes. Here we reviewed the recent progress in characteristics of fungal lignin-degrading enzymes, including lignin peroxidase(LiP), manganese peroxidase(MnP), laccase and versatile peroxidase(VP), and also their applications in genetic engineering and genomics research.
