In this study, the Fenton reaction, which is naturally used by fungi for wood decay, was employed to pretreat rice straw and increase the enzymatic digestibility for the saccharification of lignocellulosic biomass. Using an optimized Fenton's reagent (FeCl3 and H2O2) for pretreatment, an enzymatic digestibility that was 93.2% of the theoretical glucose yield was obtained. This is the first report of the application of the Fenton reaction to lignocellulose pretreatment at a moderate temperature (i.e., 25°C) and with a relatively high loading of biomass (i.e., 10% (w/v)). Substantial improvement in the process economics of cellulosic fuel and chemical production can be achieved by replacing the conventional pretreatment with this Fenton-mimicking process.
在这项研究中,我们利用真菌自然用于木材腐烂的芬顿反应预处理水稻秸秆,以提高木质纤维素生物质的酶解糖化率。通过使用优化的芬顿试剂(FeCl3 和 H2O2)进行预处理,获得了 93.2%的理论葡萄糖得率的酶解糖化率。这是首次在温和温度(即 25°C)和相对较高生物质负荷(即 10%(w/v))下将芬顿反应应用于木质纤维素预处理的报道。通过用这种模拟芬顿的方法替代传统预处理,可以显著提高纤维素燃料和化学品生产的工艺经济性。
