The influences of xylan on the properties of bacterial cellulose nanocrystals

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

In plant cell wall, cellulose is imbedded in a matrix consisting of cell wall polysaccharides such as hemicelluloses and pectin. The cellulose-cell wall polysaccharides interaction and its effects on cellulose microfibril assembly and crystallization using bacterial cellulose (BC) as a model system have been extensively studied. In this study, the impacts of xylan on the properties of bacterial cellulose nanocrystals (BCNCs) were investigated. G. hansenii (ATCC 23769) was chosen as a model strain to produce BC control and BC/xylan pellicles. The pellicles were subsequently subjected to acid hydrolysis at the same conditions to produce different nanocrytsals. Atomic force microscopy (AFM) observation indicated that xylan could promote BCNCs bundling and tailor the geometrical dimensions of BCNCs.
