文摘内容 Gt factor is a low-molecular-weigh peptide isolated from the extraccllular culture of wood-degrading fungus Gloeophyllum trabeum. It is capable of enhancing degradation of cellulose.Its action mechanism was investigated and it was found that Gt factor could reduce Fe^3+ to Fe^2+. Electron paramagnetic resonance (EPR) spectroscopy revealed in the presence of O2,Gt factor could drive the formation of H2O2 via a superoxide anion O2^·- intermediate and mediate the generation of hydroxyl radical HO^·in a Fehton-type reaction. All these provided evidence for the formation of HO^·in some wood-degrading fungi。
