白腐真菌处理难降解有机物的培养条件及应用研究

The Culturing Conditions and Application of White Rot Fungi Degrading the Refractory Organic Pollutants

白腐真菌能够通过产生胞外氧化酶——木质素过氧化物酶、锰过氧化物酶和漆酶等酶,直接参与各种难降解有机污染物和毒性物质的降解,它的这种独特的降解能力和降解机制,多年来一直受到世界各国科学界以及工业界的高度重视。本文综述了不同培养条件包括不同基础培养基、添加不同外源(如微量元素等)、不同载体、不同菌体混合以及非灭菌条件等对白腐真菌生长状况与产酶情况的影响,同时就目前白腐真菌在工业废水(皂素废水、漂白废水、DDNP废水)、生物肥料和生物制浆等领域的应用基础研究进展作一综述,并对其进一步地研究作了展望。

Various extracellular oxidases including lignin peroxidase, Mn peroxidase and laccase produced by white rot fungi could directly involve in the degradation of various refractory organic pollutants and toxic compounds. The special functions and degradation mechanism of white rot fungi have been paid much attention to the scientific communities all of the world and industrial fields for many years. The effects of various culturing conditions,such as different basic culturing media, extra outside sources （ microetements et al） , carriers, mixed fungi, non-sterile condition on the growth and ligninolytic enzymes production of the white rot fungi were reviewed in this paper,as well as the advances of the research of their application, including industrial wastewater, bio-fertilizer and bio - pulping.
