White rot fungi use a variety of mechanisms to accomplish the complete degradation of lignin and a wide variety of environmental pollutants. Both oxidative and reductive reactions are required for the metabolism of both lignin and environmental pollutants. The fungi secrete a family of peroxidases to catalyze both direct and indirect oxidation of chemicals. The peroxidases can also catalyze reductions using electron donors to generate reductive radicals. A cell-surface membrane potential can also be used to reduce chemicals such as TNT.
白腐真菌利用多种机制实现木质素和多种环境污染物的完全降解。木质素和环境污染物的代谢都需要氧化反应和还原反应。真菌分泌一类过氧化物酶来催化化学物质的直接氧化和间接氧化。过氧化物酶还可以利用电子供体催化还原反应以产生还原自由基。细胞表面膜电位也可用于还原诸如三硝基甲苯之类的化学物质。
