微波 (MW) 辅助酸水解源自博德 (Styrax tonkinensis) 木材的木质纤维素材料生成葡萄糖，以找到废弃筷子的有效用途。 MW辅助酸水解（来自1克未经处理的博德木纤维素）产生的葡萄糖的最大量为0.48克，是通过使用1.0%（w/w）硫酸作为催化剂在200°C下加热1分钟获得的。然而，MW 辅助酸水解（0.16 g）和处理残渣（0.52 g）酶水解的最大总葡萄糖产量均为 0.68 g，这是使用 1.0%（w/w）硫酸作为催化剂，在 180 °C 微波加热温度下 5 分钟获得的。总之，结果表明，使用 1.0% (w/w) 硫酸作为催化剂在 200 °C 下进行微波辅助处理可促进博德木纤维素的微波辅助酸水解，而在 180 °C 下进行处理可作为处理后残留物酶水解的预处理。
Microwave (MW)-assisted acid hydrolysis of lignocellulosic material derived from bode (Styrax tonkinensis) wood to glucose was performed to find effective uses for discarded chopsticks. The maximum amount of glucose produced by MW-assisted acid hydrolysis (from 1 g of untreated bode wood cellulose) was 0.48 g, and was obtained by heating at 200 °C for 1 min using 1.0% (w/w) sulfuric acid as catalyst. However, the maximum total glucose yield from both MW-assisted acid hydrolysis (0.16 g) and enzymatic hydrolysis of the treated residue (0.52 g) was 0.68 g, which was obtained at a microwave heating temperature of 180 °C for 5 min using 1.0% (w/w) sulfuric acid as catalyst. In conclusion, the results showed that microwave-assisted treatment at 200 °C using 1.0% (w/w) sulfuric acid as catalyst facilitated MW-assisted acid hydrolysis of bode wood cellulose and treatment at 180 °C served as pretreatment for enzymatic hydrolysis of the treated residue.
