Valentin Guigon presented the results of his research work entitled Study of depolymerization processes of oligosaccharides from hemicelluloses in a biorefinery.
The lignocellulosic biomass is composed of 30% hemicelluloses, which are small polysaccharides. They can lead to interesting chemical platforms that can be declined in various products arousing a growing interest.
In a wood based biorefinery, hemicelluloses were solubilized by water pre-hydrolysis under the form of monosaccharides and oligosaccharides. Then, secondary hydrolysis were performed to convert those oligosaccharides to monosaccharides (acid hydrolysis) or xylans to xyloses (enzymatic hydrolysis).
