Bacterial cellulose (BC), an exopolymer of Gluconacetobacter sp. bacteria, a subgenus of Acetobacter, has many unique properties such as a sophisticated 3D porous network, long fibre, high crystallinity,
high water absorption, and retention capacity. The BC chemical structure is composed by (1→4)-D-anhydroglucopyranose chains bounded through β-glycosidic linkages. BC’s geometry is determined by the intra-molecular and inter-molecular hydrogen-bonding network, hydrophobic and van der Waals interactions, and forms parallel chains (Cellulose Type I).
