    Synergistic Antimicrobial Effects of Activated Lactoferrin and Rosemary Extract in Vitro and Potential Application in Meat Storage
    (Springer Verlag, 2020) Soyer, Ferda; Keman, Deniz; Keman, Deniz; Soyer, Ferda; Eroğlu, Erdal; Türe, Hasan; 01. Izmir Institute of Technology; 04.03. Department of Molecular Biology and Genetics; 04. Faculty of Science
    This study aimed to explore the antimicrobial effects of activated lactoferrin (ALF) and rosemary extract (RE) on Escherichia coli O157:H7, Salmonella Enteritidis and Listeria monocytogenes, and to investigate their application potential in the meat storage. Minimum inhibitory concentrations (MICs) of ALF, RE and ALF-RE combinations were determined via microtiter plate assay. MICs of ALF were 1% for E. coli O157:H7; 0.5% for S. Enteritidis and 0.1% for L. monocytogenes. While 15% RE inhibited L. monocytogenes; 30% RE partially inhibited E. coli O157:H7 and S. Enteritidis growth. Synergistic effect of ALF and RE on the inhibition of E. coli O157:H7 increased the activity of ALF two to three folds. Food application of antimicrobials was performed by dipping of meat samples. Both ALF and RE were found effective in the prevention of L. monocytogenes growth about two logs. According to the data, choice of natural antimicrobials may be promising in food preservation.

    Physical Properties of Biopolymers Containing Natamycin and Rosemary Extract
    (John Wiley and Sons Inc., 2009) Türe, Hasan; Özen, Fatma Banu; Eroğlu, Erdal; Soyer, Ferda; Özen, Banu; Soyer, Ferda; 04.03. Department of Molecular Biology and Genetics; 03.08.

    Antifungal biopolymers were prepared by incorporating natamycin (NA) and NA + rosemary extract (RE) into wheat gluten (WG) and methyl cellulose (MC) films. Interaction between antimicrobial agents and biopolymers was determined with mid-infrared spectroscopy and scanning electron microscopy (SEM). Water vapour permeability and mechanical properties of these films were also measured. Mid-infrared spectroscopy did not indicate any interaction. SEM observations showed that NA crystallises at high concentrations in biopolymers. There were no significant changes in water vapour permeabilities of biopolymers containing active agents at P < 0.05. While NA incorporation did not result in any changes in mechanical properties of WG films a reduction in tensile strength was observed for MC films containing high concentration of NA. In general, active agent incorporation into WG and MC films did not result in any considerable changes in their physical properties that could affect their application.

    Antifungal Activity of Biopolymers Containing Natamycin and Rosemary Extract Against Aspergillus Niger and Penicillium Roquefortii
    (John Wiley and Sons Inc., 2008) Türe, Hasan; Eroğlu, Erdal; Soyer, Ferda; Özen, Fatma Banu; Özen, Fatma Banu; 04.03. Department of Molecular Biology and Genetics; 03.08. Department of Food Engineering; 03. Faculty of Engineering; 04. Faculty of Science; 01. Izmir Institute of Technology
    Antimicrobial agent-releasing films have been proposed as an effective way of inhibiting chiefly surface spoilage of food products. Antifungal activities of natamycin (NA), rosemary extract (RE) and NA + RE were tested against Aspergillus niger and Penicillium roquefortii with agar disc diffusion assay. NA, RE and NA + RE were also included into biopolymers made from gluten and methyl cellulose. Minimum inhibitory concentrations (MIC) of NA in both films were 2 and 1 mg NA per 10 g film solution against A. niger and P. roquefortii, respectively. RE did not show any inhibitory antifungal activity alone. Although NA incorporated into both films at a concentration of 1.5 mg NA per 10 g film solution was not effective against A. niger, combination of NA at the same concentration with RE in the films inhibited the growth of this mould. NA in solution or in biopolymers is very effective in inhibiting the growth of selected organisms, and RE acted synergistically with NA to prevent the growth of A. niger when incorporated into both films. © 2008 Institute of Food Science and Technology
