Nisin, an important bacteriocin from Lactococcus lactis subsp., is primarily active against various Gram-positive bacteria. Leucocin C, produced by Leuconostoc carnosum 4010, is a class IIa bacteriocin used to inhibit the growth of Listeria monocytogenes. Because two bacteriocins have different modes of action, the combined use of them could be a potential strategy for effective inhibition of f...

stevia rebaudiana bertoni, is an ancient perennial shrub of south america, with great potential as a crop for the production of high-power natural sweetener. due to its chemical composition and content of the phytochemical compounds, it is suitable as a raw material for the extraction and production of functional foods. diterpene glycosides component of low-calorie sweetener is approximately 30...

<p class="Abstract">The essential oil can inhibit pathogenic bacterial activities, which be developed to a natural preservative for food. This research aimed evaluate the antibacterial activity of oils from five species Syzygium on <em>Bacillus cereus</em>, <em>Escherichia coli</em>, <em>Listeria monocytogenes</em>,<em> Staphylococcus aureus,</...

AIMS To evaluate the effectiveness of various antimicrobial mortar formulations in inhibiting the growth of a selection of pathogens of environmental and hygienic concern. METHODS AND RESULTS Mortar prisms containing triclosan-incorporated fibres or different concentrations of silver copper zeolites were incubated with Escherichia coli, Listeria monocytogenes, Salmonella enterica or Staphyloc...

The objective of this study was to produce phage display-derived binders with the ability to distinguish Listeria monocytogenes from other Listeria spp., which may have potential utility to enhance detection of Listeria monocytogenes. To obtain binders with the desired binding specificity a series of surface and solution phage-display biopannings were performed. Initially, three rounds of surfa...

Lemon peel waste (LPW) were pyrolysed in a laboratory fixed-bed reactor at final temperature of 300 °C, 400 °C and 500 with an incremental heating rate 10 °C/min, under N2 atmosphere to produce biochar, bio-oil gas. The maximum yields bio-oil, biochar gas 16.66 wt%, 66.89 wt% 54.6 respectively, °C. produced has calorific value around 12 MJ/N m3 composition up 68.82 vol.% CO, 5.25 CH4, 1.48 CnHm...

The main objective of this study was to investigate the effectiveness ultraviolet light (UV-C) emitting diodes for decontamination stainless steel food contact surfaces. Listeria monocytogenes (ATCC 19115), Escherichia coli 25922), and Salmonella enterica serovar Typhimurium 700720) were chosen as challenge microorganisms. Target microorganisms subjected UV-C dosages 0, 2, 4, 6, 8 mJ cm −2 at a...

Squamous mucosal epithelial cells constitutively express calprotectin in the cytoplasm. To study how this antimicrobial protein complex confers epithelial resistance to invading bacteria, an epithelial cell line was stably transfected to express the calprotectin complex. Cells expressing calprotectin resist invasion by Listeria monocytogenes and Salmonella enterica serovar Typhimurium. Calprote...

Background: Zataria multiflora boiss is a member of Lamiaceae family with antibacterial, antifungal, and antioxidant activity. The aim of this study was to evaluate chemical composition and antibacterial effect of Zataria multiflora essential oil against two foodborne pathogens in meat. Methods: The inhibitory effect of Zataria multiflora essential oil (Minimum inhibitory concentration and Min...

We developed a screening procedure to identify small-molecule compounds that altered infection by Listeria monocytogenes to gain insights into bacterial/host cellular processes required for intracellular pathogenesis. A small-molecule library of 480 compounds with known biological functions was screened, and 21 compounds that altered the L. monocytogenes infection of murine bone marrow-derived ...
