Fig. 1From: Xylan extraction from pretreated sugarcane bagasse using alkaline and enzymatic approachesFTIR spectra of alkali-extracted GAXs. Blue and red lines refer to alkali-extracted GAXs by Lopez and Hoije methods, respectively. Enzymatically extracted GAX was not analyzed because it contained small amounts of residual phosphate buffer, which interfered in the FTIR bands of this sampleBack to article page
