Antibacterial effects of biodegradable chitosan- Papia Undulata shell composite films

In this investigation, a chitosan-Papia Undulata shell composite film was obtained by casting evaporation method. The physical properties and the influence of chitosan-Papia Undulata shell composite films on the antibacterial were investigated. The effects of Papia Undulata shell on the chitosan film are determined with Fourier Transform Infrared Spectroscopy (FTIR), Energy Dispersive X-Ray Fluorescence (EDXRF) and X-Ray Diffraction (XRD), respectively. On the other hand for evaluated the antibacterial activity, the chitosan-Papia Undulata shell composite films investigate against Gram-negative (E.coli) bacterial. The results revealed that the chitosan-Papia Undulata shell composite films can be inhibiting target microorganisms. Another that, the chitosan-Papia Undulata shell composite films has particles of Papia Undulata shell distribution in the chitosan film which corresponding with the result of XRD pattern, while the results of FTIR suggest that the chitosan-Papia Undulata shell composite films can be modified by the addition of Papia Undulata shell.
