【 摘 要 】

Biofilm based on gellan gum, was prepared by evaporative casting technique, and its properties were evaluated. The tensile strength (TS) and elongation-at-break (EAB) of the GGVCO-NOR films were found to be 9 MPa and 7.3%, respectively. The swelling properties and water vapor transmission rates of the prepared films were found to be 278% and 212 g m-2 d-1, respectively, after 24 hours. Surface morphology of the film revealed the presence of the pores. From the anti-bacterial study, it was found that the inhibition zone of GG-NOR and GG-VCONOR film were 5.30.06 mm and 5.7-0.06 mm against gram-positive (Staphylococcus aureus) and 5.0-0.01 mm and 6.3-0.06 mm againts gram-negative bacteria (Escherichia coli).
