xylan on cellulose nanowhiskers matrix
Due to the ever-increasing global demand for materials, international dependence on conventional petroleum resources and environmental concerns, there is considerable interest in the development of alternative and sustainable products, manufactured by green technologies. In an effort to address these challenges, cellulose, the most globally abundant naturally occurring polymer has attracted sig...
متن کاملModification of Bacterial Cellulose Biofilms with Xylan Polyelectrolytes
The effect of the addition of two [4-butyltrimethylammonium]-xylan chloride polyelectrolytes (BTMAXs) on bacterial cellulose (BC) was evaluated. The first strategy was to add the polyelectrolytes to the culture medium together with a cell suspension of the bacterium. After one week of cultivation, the films were collected and purified. The second approach consisted of obtaining a purified and h...
متن کاملRole of hydrogen bonding in the interaction between a xylan binding module and xylan.
NMR studies of the internal family 2b carbohydrate binding module (CBM2b-1) of Cellulomonas fimi xylanase 11A have identified six polar residues and two aromatic residues that interact with its target ligand, xylan. To investigate the importance of the various interactions, free energy and enthalpy changes have been measured for the binding of xylan to native and mutant forms of CBM2b-1. The da...

Ice templated and cross-linked xylan/nanocrystalline cellulose hydrogels.
Structured xylan-based hydrogels, reinforced with cellulose nanocrystals (CNCs), have successfully been prepared from water suspensions by cross-linking during freeze-casting. In order to induce cross-linking during the solidification/sublimation operation, xylan was first oxidized using sodium periodate to introduce dialdehydes. The oxidized xylan was then mixed with CNCs after which the suspe...
