A green process for the microwave-assisted hydrothermal selective dissolution and utilisation of hemicellulose in Phyllostachys heterocycla cv. Pubescens (shortened to pubescens) was developed. The process facilitated the efficient dissolution of hemicellulose at 200 °C, while obtaining hemicellulose-free residue that could be further used as starting materials within many industrial processes. A variety of analytical techniques (e.g., HPLC, FT-IR, SEM, TG/TGA, Py-GC/MS, TG-IR, 13C liquid NMR, 2D HSQC NMR, and 13C CPMAS NMR analysis) were used for the analysis of the obtained liquid and solid products, which revealed that hemicellulose was completely extracted from pubescens. A solid residue left after this process consists of cellulose and lignin in a pure form and can be used for production of glucose and aromatic compounds. Interestingly, a new route to produce hemicellulose-based films that could potentially be used for food packaging was achieved. The developed approach opens avenue for a low-cost and sustainable bamboo-based biorefinery.

微波辅助水热选择性溶解和利用毛竹中的半纤维素。耻骨
微波辅助Phyllostachys heterocycla cv中半纤维素的水热选择性溶解和利用的绿色过程。开发了Pubescens（缩写为pubescens）。该方法促进了半纤维素在200°C时的有效溶解，同时获得了无半纤维素残留物，该残留物可在许多工业过程中进一步用作起始原料。多种分析技术（例如HPLC，FT-IR，SEM，TG / TGA，Py-GC / MS，TG-IR，13 C液相NMR，2D HSQC NMR和13 C CPMAS NMR分析）被用于分析。所得液体和固体产物的分析表明半纤维素是完全从耻骨中提取的。此过程后残留的固体残留物由纯净的纤维素和木质素组成，可用于生产葡萄糖和芳香族化合物。有趣的是，实现了生产可能用于食品包装的基于半纤维素的薄膜的新途径。发达的方法为低成本和可持续的竹基生物精炼厂开辟了道路。
