文摘

The structural changes and cellulose accessibility of bagasse was investigated. Cellulose accessibility increased with the increase in the acid pretreatment severity. Accessibility was linearly correlated with glucose yield after hydrolysis. Lignin modification/reallocation is key factor for improving cellulose accessibility.
