Figure 2From: Chemical and morphological characterization of sugarcane bagasse submitted to a delignification process for enhanced enzymatic digestibilityCPMAS-TOSS NMR spectra of sugarcane bagasse. (a) Untreated; (b) bagasse treated with acid (H2SO4 1.0%) and (c) bagasse treated with acid and NaOH 4.0%. The spectra were normalized by the intensity of line 10 (C1 carbon of cellulose). CPMAS-TOSS: cross polarization under magic angle spinning with total suppression of spinning sidebands; NMR: nuclear magnetic resonance.Back to article page
