Fenton's reagent, ultrasound, and the combination of Fenton's reagent and ultrasound were used to pretreat rice straw (RS) to increase its enzymatic digestibility for saccharification. The characterization shows that compared with ultrasound, Fenton's reagent pretreatment was more efficient in increasing the specific surface area and decreasing the degree of polymerization (DP) of RS. The enzymatic hydrolysis results showed that the RS pretreated by ultrasound-assisted Fenton's reagent (U/F-RS), which exhibited the largest specific surface area and the lowest DP value, had the highest enzymatic activity, and the amount of reducing sugar released from U/F-RS at 48h of enzymatic saccharification is about 4 times as large as that from raw RS and 1.5 times as large as that from Fenton's reagent pretreated RS. The ultrasound-assisted Fenton process provides a reliable and effective method for RS pretreatment.
芬顿试剂、超声波以及芬顿试剂和超声波的联合使用被用于预处理水稻秸秆（RS）以提高其酶解糖化的可消化性。特性分析表明，相较于超声波，芬顿试剂预处理在提高 RS 的比表面积和降低聚合度（DP）方面更为有效。酶水解结果表明，经过超声辅助芬顿试剂（U/F-RS）预处理的 RS 表现出最大的比表面积和最低的 DP 值，具有最高的酶活性，并且在酶糖化 48 小时时，从 U/F-RS 释放的还原糖量约为原始 RS 的 4 倍，是芬顿试剂预处理 RS 的 1.5 倍。超声辅助芬顿工艺为 RS 的预处理提供了可靠且有效的方法。
