In this study, sugar cane bagasse was pretreated by [BMIM]Cl and polyethyleneglycol (PEG) to enhance the enzymatic conversion and consequently the fermentation yield of the lignocelluloses. The structural changes of the raw and PEG assisted ionic liquid pretreated lignocellulosic sample was investigated to understand that how this combination is efficient for lignnocelluloses pretreatment. The process was optimized and the structural analysis was conducted on samples pretreated at optimum condition. Fourier transform- infrared spectroscopy was mainly used to evaluate the various structural changes in the sugar cane bagasse. Lateral order index (LOI) and total crystallinity index (TCI) was calculated from Ft-IR data as two parameters to evaluate the pretreatment impacts.
