To elevate the glucose yield from the enzymatic hydrolysis of poplar wood for bio-ethanol production, quick hydrothermal treatment (QHT) was conducted at 200 °C for a short period of time from 5 min to 25 min. It was found that the QHT could remove >85% of the hemicelluloses and ~30% of the lignin in the poplar wood, and achieve 82% cellulose conversion at a low cellulase dosage of 10 FPU/g substrate. The enhancement digestibility of poplar wood was ascribed to the higher accessibility of cellulose, as the specific surface area of the substrate increased from 3.0 m2/g to 7.1 m2/g from the of untreated wood to the QHT-treated wood. The results demonstrate the improvements in digestibility and hydrolysis rates after QHT.

快速水热处理提高了杨木的酶消化率。

为了提高杨木经酶促水解生产生物乙醇的葡萄糖产量，在200°C下进行了5分钟到25分钟的短时间快速水热处理（QHT）。研究发现，在10 FPU / g底物的低纤维素酶剂量下，QHT可以去除> 85％的半纤维素和〜30％的木质素，并实现82％的纤维素转化率。杨木木材消化率的提高归因于纤维素的较高可及性，因为基材的比表面积从未经处理的木材到经QHT处理的木材从3.0平方米/克增加到7.1平方米/克。结果证明了QHT后消化率和水解速率的改善。
