(1:2 molar ratio) was found to be the best solvent for pretreating bamboo shoot shell
with the highest xylan removal (53%) and delignification (48%). After deep eutectic
solvent addition, more surface areas in the pretreated bamboo shoot shell were
formed which allowed cellulases to further attack cellulose and residual hemicellulose. Thus, enzymatic saccharification of bamboo shoot shell was increased after
deep eutectic solvent pretreatment. The reducing sugars yield from the enzymatic
hydrolysis of 50 g/L deep eutectic solvent bamboo shoot shell was maximal (90%).
Furthermore, it was found that combination pretreatment was better than one-step
pretreatment, and it effectively removed xylan and lignin after treatment with deep
eutectic solvent (Dai et al. 2017).
