چکیده انگلیسی
This study aimed to characterize the structural and physico-mechanical properties of bacterial cellulose (BC) produced by Gluconoacetobacter xylinus TJU-S8 which was isolated from Chinese persimmon vinegar. Thermogravimetric analysis (TGA) showed that BC exhibited a good thermal stability. Solid-state nuclear magnetic resonance (NMR), fourier transform infrared spectroscopy (FT-IR) and x-ray diffraction (XRD) analysis revealed that BC had a typical crystalline form of the cellulose I. The BC membrane had typical characteristics such as nanodimensional network and microfibrils obtained by scanning electron microscopy (SEM). Moreover, the bacterial cellulose chitosan (BC-C) membrane and bacterial cellulose carboxymethyl chitosan (BC-CC) membrane were synthesized which showed significant inhibition against the growth of both Escherichia coli and Staphylococcus aureus. These results indicated superior properties of BC that advocated its effectiveness for various applications.
