Valentin Guigon, Ph.D. student of LGP2, defended his thesis:, Ph.D. student of LGP2, defended his thesis: "Study of depolymerization processes of oligosaccharides from hemicelluloses in a biorefinery".

This University Grenoble Alpes doctoral thesis was prepared under the supervision of the Professor Christine Chirat, and of Professor Emeritus Dominique Lachenal (Grenoble INP-Pagora / LGP2).

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 30% composed of hemicelluloses, themselves composed of saccharides. Real chemical platforms, these can be declined in various products arousing a growing interest.

In a 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).
