Electrospun Cactus Mucilage/Poly(vinyl alcohol) Nanofibers as a Novel Wall Material for Dill Seed Essential Oil (Anethum graveolens L.) Encapsulation: Release and Antibacterial Activities
This study, a collaboration work with University of Sfax and Grenoble INP, aimed to create long-lasting molecular carriers by producing electrospun nanofibers from cactus mucilage and poly(vinyl alcohol) loaded with dill seed (Anethum graveolens L.) essential oil (DSEO). The electrospun nanofibers enabled controlled long-term release of DESO. The DSEO-containing nanofibers demonstrated bacteriostatic and bactericidal activities […]
Enantioselective membranes prepared by electrospinning of cellulose tris(3,5-dimethylphenyl carbamate) having various degrees of polymerization: effect of the DP on the morphology
Recently, we reported a proof of concept of enantioselective membrane filtration using a nonwoven membrane prepared by electrospinning of cellulose tris(3,5-dimethylphenyl carbamate) (CDMPC) synthesized from microcrystalline cellulose. In the present work, CDMPCs having higher degrees of polymerization were synthesized from cellulose fibers derived from hardwoods by a collaboration with Centre Technique du Papier granted by […]

Sugars, a new weapon against infections!
Glycobiology, the study of the biological functions of carbohydrates, is a field of research in its own right, which could one day lead to new treatments against infections. Anne Imberty, CNRS Research Director at Cermav, was interviewed in the CNRS journal on this topic, with Yann Guérardel as co-guest. The article is available here: https://lejournal.cnrs.fr/articles/les-sucres-nouvelle-arme-contre-les-infections […]

Supramolecular carbohydrate-based hydrogels from oxidative hydroxylation of amphiphilic β-C-glycosylbarbiturates and α-glucosidaseinduced hydrogelation
The team “Self-assembly of Glycopolymers” of CERMAV has developed a new family of sugar derivatives through an eco-responsible process which is able to self-assemble into hierarchical glyconanostructures to ultimately gel water and the gelation can be triggered by the action of a glycosidase.

Hijacking the Peptidoglycan Recycling Pathway of Escherichia coli to Produce Muropeptides
Muropeptides are short peptidoglycan fragments released from the cell wall of bacteria as part of their metabolism or as a result of biological stresses, in which they play a major role in the induction of antibiotic resistance. In order to better understand these processes, we developed a new synthetic approach which combines synthetic biology and glycochemistry to prepare Gram (–) and Gram (+) muropeptides.
