Structural characterization by (a) Fourier transform infrared spectrometry and (b) powder X-ray diffraction analysis of untreated sugarcane bagasse fraction superior to 315 µm (SCB > 315), and fractions extracted by: auto-hydrolysis followed by organosolv with ethanol (AuH_EtOH); organosolv with ethanol (EtOH); auto-hydrolysis at 190 °C (AuH_190); auto-hydrolysis at 180 °C (AuH_180); and auto-hydrolysis at 170 °C (AuH_170), in comparison with commercial cellulose (CC) used as control. CI averages followed by the same letters do not differ statistically by Tukey’s test (p  <  0.05).
