Abstract

A bacterial cellulose/chitosan (BC-C) biocomposite material was obtained by microbial synthesis under static condition with the use of Gluconacetobacter xylinus InaCCB404 and addition of chitosan in varied concentration. The BC and BC-C biocomposites were examined for the chemical composition by FTIR, the crystallinity by XRD, the tensile strength by tensile tester, the color by chromameter and the water vapor permeability (WVP). The spectra resulted from FTIR analysis showed an intermolecular interaction between BC and C. The obtained biocomposite material was transparent, and display a WVP value of 2.97 – 5.94 x10-5 g.s-1.m-2.Pa-1 with crystallinity index and crystallite size lower than native BC. The BC-C biocomposites- properties showed the material potency as an edible coating for fresh cut fruits.
