Bacterial cellulose (BC), produced by bacteria of genus Gluconoacetobacter is a pure biopolymer and exhibits higher degree of polymerization and crystallinity, high water holding capacity, and better adsorption of liquids compared to plant cellulose. The micro fibril of the BC form a high reticulated structure which is stabilized by inter and intra molecular hydrogen bonds. The inspiring mechanical properties and reinforcing potentials, presence of hydrogen binding sites, abundance, and biodegradable nature of BC nanocrystals make them perfect candidate for the processing of polymer nanocomposites. The composites of BC and chitosan (BC-Ch) have been synthesized by treating BC sheets with Ch solution. In this presentation, the strategy for the higher productivity of BC production is introduced. The purpose of the preparation of BC-Ch composite is introduced and the improved physico-chemical propertied will be reported.
