摘要

Bacteriophages (phages) are obligate bacterial parasites, and their immobilization on a polymer surface facilitates their contact with the host cell on the food surface. The aim of this research was to immobilize Escherichia coli lytic phages on cellulose acetate film to control E. coli in chicken fillet. E. coli phages were isolated from wastewater. The modified cellulose acetate was placed in a suspension of the specific E. coli phages at 4 °C under slow shaking for 24 h. The antimicrobial effect of the active film was evaluated on the growth of E. coli in the chicken fillet. The results indicated the active film led to a significant reduction in the E. coli count during storage, compared with the control (phage-free film) (P ≤ 0.05). Immobilization of phages on food packaging is a proper idea to control bacterial contamination during food storage.
