Abstract

Bacterial cellulose (BC) shows good potentiality as active packaging material. However, bacterial cellulose itself has no antimicrobial activity to prevent microbial contamination. To achieve antimicrobial activity, -poly lysine ( -PL) was incorporated into BC by immersing BC in -PL solution. Investigations into the effects of -PL concentrations and contact times on incorporation of -PL into cellulose membranes showed that the lowest -PL concentration and the shortest time for production of an effective antimicrobial cellulose membrane ( -PL/BC) were 400 mg/l and 2 hours, respectively. The antimicrobial cellulose membrane was characterized by FTIR, XRD and AFM. It was found that -PL is incorporated into the BC network, and the antimicrobial cellulose membrane is not a simple mixture of BC and -PL. In this study -PL/BC membranes are demonstrated to have potential applicability as antimicrobial packaging films.
