Simultaneous utilization of non-starch polysaccharides and starch and viscosity reduction for bioethanol fermentation from fresh Canna edulis Ker. tubers

- Non-starch polysaccharides and starch can be utilized simultaneously.
- Fermentation efficiency increased and viscosity reduced after CWDE treatment.
- After CWDE treatment, starch granules changed and fibers were disrupted.
- This process can efficiently produce bioethanol from Canna edulis Ker.
