Abstract EN
Lignin-rich residues from the cellulose-based industry are traditionally incinerated for internal energy use.
The future biorefineries that convert cellulosic biomass into biofuels will generate more lignin than necessary for internal energy use, and therefore value-added products from lignin could be produced.
In this context, a good understanding of lignin is necessary prior to its valorization.
The present study focused on the characterization of lignin-rich residues from biochemical ethanol production, including steam explosion, saccharification, and fermentation, of wheat straw and olive tree pruning.
In addition to the composition and purity, the lignin structures (S/G ratio, interunit linkages) were investigated by spectroscopy techniques such as FTIR and 2D-NMR.
Together with the high lignin content, both residues contained significant amounts of carbohydrates, mainly glucose and protein.
Wheat straw lignin showed a very low S/G ratio associated with p-hydroxycinnamates (p-coumarate and ferulate), whereas a strong predominance of S over G units was observed for olive tree pruning lignin.
The main interunit linkages present in both lignins were β-O- 4 ′ ethers followed by resinols and phenylcoumarans.
These structural characteristics determine the use of these lignins in respect to their valorization.
