Résumé:	The aim of this study was to develop and characterize new bio-nanocomposite films based on alginate and montmorillonite activated with lemon essential oil (LEO). The microstructure characterisation of alginate-montmorillonite/LEO (alg-MMT/LEO) nanocomposites was performed using X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) and the surface morphology of the films was examined using light microscopy. The XRD and FTIR results confirmed MMT exfoliation and revealed the presence of strong interaction between alginate and MMT in the presence of LEO. Powerful antimicrobial and antifungal properties of the films alg/MMT improved by (0.5%,1%and 1.5%) LEO was evaluated by two methods: disc diffusion and by enumeration of bacteria.
