    Abstract Background: The present study aimed to determine the antimicrobial effects of Lactobacillus acidophilus and Lactobacillus reuteri against Campylobacter jejuni in fresh and roasted chicken breast fillets. Methods: Fresh and roasted chicken breast fillets were soaked in probiotic suspensions (11 log CFU/ml) and immersed in C. jejuni suspension (5 and 3 log CFU/ml). Afterwards, the fillets were placed in clean stomacher bags and refrigerated for 10 days until further analysis. Results: The count of 5 log CFU/g in the fresh fillets treated with L. acidophilus, L. reuteri, L. reuteri, and L. acidophilus reached 3.45, 3.89, and 4.25 log CFU/g after 10 days of refrigerated storage, respectively. In the roasted fillets, the corresponding counts were estimated at 2.99, 3.54, and 3.92 log CFU/g, respectively. In addition, the inoculated 3 log CFU/g of C. jejuni reached 1.09-1.11 log CFU/g after the refrigerated storage of the fresh and roasted chicken breast fillets. Conclusion: According to the results, the addition of L. acidophilus and L. reuteri to the fresh and roasted chicken breast fillets had inhibitory effects against the growth of C. jejuni.

    Abstract Introduction : Consumption of appropriate amount of probiotic microorganisms via food products have health benefits on the host. In recent years, there has been a significant increase in research on the characterization and verification potential use of probiotic films in food industry. The aim of the current study was to investigate in vitro antimicrobial property of probiotic carboxymethyl cellulose-sodium caseinate (CMC-SC) films containing Lactobacillus acidophilus , L. reuteri and Bifidobacterium bifidum against Listeria monocytogenes , Salmonella typhimurium , Staphylococcus aureus and Escherichia coli O157:H7. Methods : Preparation of CMC-SC composite films were conducted based on casting method. The in vitro antibacterial property of CMC-SC films was evaluated using agar disk diffusion and broth micro-dilution methods. Results : Antimicrobial property of probiotic films (diameter inhibition zone and log differences in population, respectively) were as follow: S. aureus (2.13-5.65 mm and -0.79 - -3.82) > L. monocytogenes (1.76-5.32 mm and -0.65 - -3.34) > S. typhimurium (2.13-4.33 mm and -0.34 - -2.79) > E. coli O157:H7 (1.88-3.86 mm and -0.18 - -2.62). The best antimicrobial property against aforementioned bacterial pathogens was found for film supplemented with L. acidophilus + L. reuteri + B. bifidum. Conclusion : It can be concluded that incorporation of some probiotic strains into edible films resulted in excellent antimicrobial property against S. aureus , L. monocytogenes, S. typhimurium and E. coli O157:H7 and probably solve safety related issue in food industry.
