Multifunctional Bacterial Cellulose/Chitosan Composite Materials for Medical Applications

This paper presents some results concerning the characterisation of the structural parameters of bacterial cellulose/chitosan composite materials with regard to their medical application. Some chemical-physical, mechanical and biological properties of modified bacterial cellulose are presented. The innovatively-modified bacterial cellulose characterised by the combined properties of both cellulose and chitosan (especially high susceptibility for enzymatic degradation and bioactivity) is produced by the Acetobacter xylinum strain adapted to a medium containing polyaminosaccharide modifiers.
