Effects on Lignin Redistribution in Eucalyptus globulus Fibres Pre-Treated by Steam Explosion: A Microscale Study to Cellulose Accessibility

Abstract: The objective of this study was to investigate structural changes and lignin redistribution in Eucalyptus globulus pre-treated by steam explosion under different degrees of severity (S0), in order to evaluate their effect on cellulose accessibility by enzymatic hydrolysis. Approximately 87.7% to 98.5% of original glucans were retained in the pre-treated material. Glucose yields after the enzymatic hydrolysis of pre-treated material improved from 19.4% to 85.1% when S0 was increased from 8.53 to 10.42. One of t… Show more

“…The obtained sample was analyzed by HPLC to determine the xylose content in the initial sample. To convert the concentration of monomeric xylose to xylan, the factor 0.88 was used, calculated based on the water molecules gained during the hydration of the xylans [42]. Furfural was analyzed by gas chromatography (GC-FID) and mass spectrometry using a GC-MS instrument (Shimadzu GCMS-QP5050) with helium as the carrier gas.…”
