Increase in ethanol production from sugarcane bagasse based on combined pretreatments and fed-batch enzymatic hydrolysis

- Enzymatic hydrolysis in fed-batch with pretreated sugarcane bagasse.
- Glucose concentration remained constant after 30 h due to higher lignin content.
- Fed-batch addition of both material led to higher glucose concentration with 12-h.
- The delignification and fed-batch hydrolysis led to an increase ethanol production.
