Figure 2: ATR- FTIR spectra of lignocellulosic materials. (A) sugarcane bagasse, (B) wheat straw, (C) corn cobs, (D) rice straw; Raw material (dotted line), dilute acid treated (thick line). The prominent structural changes observed in all tested LCMs after acid hydrolysis expect in rice straw indicated its low amenability towards the set of hydrolysis conditions employed. The band 1511-1642 cm-1 corresponds to lignin whereas 1740-1760 cm-1 ascribed to hemicelluloses. Analysis was performed in duplicates and best of the two was represented.
