Abstract

Bacterial cellulose (BC) and oxidized BC (OBC) nanobiocomposites, incorporating alginate and zinc acetate (as Zn2+ precursor) with different concentrations, have been prepared. Periodate oxidation used to obtain OBC. According to the ATR-FTIR spectra, intermolecular interactions between the functional groups of BC and OBC, and carboxyl groups of alginate were confirmed. Characteristic diffraction peaks of ZnO nanoparticles (NPs) in nanobiocomposites containing zinc acetate confirmed the formation of ZnO nanoparticles. Water absorption was decreased with increasing alginate concentration due to the molecular chains accumulation and entanglement. Cross-linking of Zn2+ ions with alginate and BC or OBC led to decrease in water absorption and increase in tensile strength with increasing zinc acetate concentration up to 5% (w/v). The percentage of ZnO NPs in the BC-Alg3-ZnAc5 nanobiocomposites was the highest (36.2%), which was in accordance with the results obtained According to the FE-SEM micrographs, OBC revealed a more open structure with larger pores. An accumulated, chain-like, and strong structure was shown in combination of 3% alginate and 5% zinc acetate. BC-Alg0-ZnAc5 nanobiocomposites represented the highest antibacterial activity against Escherichia coli and Staphylococcus aureus. Moreover, nanobiocomposites were more sensitive against S. aureus than E. coli.
