Gt factor, a pure component isolated from Gloeophyllum trabeum, was used to decompose lignin materials. The radical intermediates, degradation products and structural changes of treated materials were analyzed by infrared spectrum, NMR and electron paramagnetic resonance, etc. The results indicate that Gt factor makes an oxidative attack on lignin via HO., which might be the initial step in lignocellulose degradation by brown rot fungus.
Gt因子是从密粘褶菌中分离得到的一种纯成分，用于分解木质素材料。通过红外光谱、核磁共振和电子顺磁共振等方法分析了处理后材料的自由基中间体、降解产物和结构变化。结果表明，Gt因子通过羟基自由基对木质素进行氧化攻击，这可能是褐腐菌降解木质纤维素的起始步骤。
