Abstract: Biodegradation is definitely an attractive tool which is currently of interest, as this is an environment-friendly and cost-competitive alternative. To date, wood decaying fungi are found to be among the most potent higher microorganisms in depolymerizing lignocellulose and degrade recalcitrant aromatic compounds. Exploring the mechanism of biodegradation by wood decaying fungi is an important job in the area of developing biomass energy and protecting ecological environment. Until now, nuclear magnetic resonance spectroscopy(NMR), infrared spectroscopy(IR)and ultraviolet spectroscopy(UV)have been employed for investigating the biodegraded mechanism. The purpose of the present study is to summarize the progresses of studying the biodegraded mechanism of wood decaying fungi using the three spectroscopy analytical methods, pointing that NMR can be applied for woody structure identification and decayed pattern analysis, IR can make an in-depth exploration for biodegraded mechanism, and UV can monitor the biodegraded order. Additionally, current problems on application of the spectroscopy analytical methods in biodegradation and the future work were also proposed, which may provide the theoretical basis for making better use of wood decaying fungi in biodegradation.
