Abstract

<p>In this research, a new methodology was developed to produce nanostructured composites of thermoplastic starch polymers/bacterial cellulose, throughout biosynthesis of cellulose by Gluconacetobacter medellinensis sp. nov bacteria. Due to the hydrophilic nature of starch, it was plasticizer with glycerol and cross-linked with citric acid to improve the mechanical and physical properties of nanocomposite films. Results indicate that the incorporation of cellulose nanofibrils and crosslinking process can improve mechanical and thermal properties, and suggest that these materials are promising candidates in food packing industry.</p>
