The application of strongly acidic electrolyzed water (SAEW) in a flow-through system for the treatment of recalcitrant corn stover resulted in enhanced hemicellulose degradation at 160°C and 180°C compared to hydrochloric acid treatment under the same pH. Pretreatment conditions were optimized by varying the four main factors: pH, flow rate, temperature, and reaction time. About 96% of the hemicellulose was removed when corn stover was treated at 180°C for 20min, with SAEW at pH 2.0 and a flow rate of 10mL/min. The recovery of total monomeric and oligomeric xylose in the liquid fraction reached 93%. Using 30 filter paper units of cellulase per gram of cellulose, a digestibility of 100% was achieved under these conditions. Therefore, flow-through SAEW pretreatment is an efficient way to remove hemicellulose and improve enzymatic digestibility of corn stover.
强酸性电解水（SAEW）在流动系统中的应用可用于处理顽固的玉米秸秆，与相同 pH 值下的盐酸处理相比，在 160°C 和 180°C 时可增强半纤维素的降解。通过改变四个主要因素：pH 值、流速、温度和反应时间，优化预处理条件。当玉米秸秆在 pH 值为 2.0 和流速为 10mL/min 的条件下于 180°C 下处理 20min 时，约有 96%的半纤维素被去除。液体部分中总单体和低聚木糖的回收率达到 93%。在这些条件下，每克纤维素使用 30 个滤纸单位的纤维素酶，可实现 100%的消化率。因此，流动式 SAEW 预处理是一种去除半纤维素和提高玉米秸秆酶解可消化性的有效方法。
