Fractionation of bamboo culms by autohydrolysis, organosolv delignification and extended delignification: Understanding the fundamental chemistry of the lignin during the integrated process

- Bamboo was successfully fractionated using the integrated biorefinery process.
- The autohydrolysis significantly facilitates the subsequent delignification.
- 7.6 g XOS, 16.8 g lignin, and 39.5 g pulp can be produced from 100 g bamboo.
- The lignin chemistry during the integrated process was thoroughly investigated.
