白腐真菌的广谱生物降解性研究进展

Broad-spectrum degradation capability of the white rot fungus

白腐真菌由于能够降解木质素而在地球的碳循环中发挥着不可或缺的作用。由胞外的过氧化物酶类和其他次级代谢产物组成的木质素降解系统除了能够降解木质素外,对众多的异生物质也具有广谱的生物降解性,赋予了白腐真菌巨大的环境工业应用潜力。对白腐真菌的木质素降解系统和其广谱的生物降解性进行了介绍与展望。

The white rot fungus（WRF） possesses powerful abilities for decomposition of the extensive plant material,lignocellulose,which make them indispensable in the Earth＇s carbon cycle.WRF are capable of mineralizing a wide variety of toxic xenobiotics due to the non-specific nature of their extracellular ligninolytic system comprising mainly of oxidoreductive metalloenzymes and secondary metabolites,and thus have potential applications in industry.This review mainly focus on their extracellular ligninolytic system and wide spectrum of biodegradation,as well as the potential future research area.
