Structural features of dilute acid, steam exploded, and alkali pretreated mustard stalk and their impact on enzymatic hydrolysis

- Pretreatment of mustard stalk is conducted using 3 different methodologies.
- Surface area, CrI, FT-IR, thermal analysis and cellulase accessibility of biomass studied.
- Impact of these characteristics on enzymatic hydrolysis is studied.
- Glucose yield at 2 and 72 h are well correlated with surface area and adsorption.
- Dilute acid produces maximum sugar (0.75 g/g glucan and xylan) at 10 FPU/g.
