Abstract: Lignocellulose is a great potential feedstock for bioenergy production. However the key obstacle for degrading and utilizing lignocellulose, developing biorefinery is the complicated structure of the plant cell wall. White-rot fungi are major degraders of lignocellulose in the nature. Illumination the molecular mechanism of biodegradation would provide a useful foundation for exploring the degradation process of lignocellulose and using the available biomass resource more efficiently. In recent years, some progresses have been achieved in proteomics of lignocellulose-degrading microorganism, providing important information for further exploring the biodegradation mechanism of lignocellulose. This review summarized previous research advance in intracellular proteomics, subproteomics, secretome proteomics and the interactions of degrading enzymes of white-rot fungi in the lignocellulose-degrading process, in order to illuminate its molecular mechanism in degrading lignocellulose from the point of view of proteomics.
