Biofilm is considered as a community of microorganisms in which cells adhere to each other on surfaces self-produced matrix extracellular polymer compounds. In recent years, efforts use the beneficial aspects biofilm probiotic research have intensified. this study, biofilms

In this study, the effect of edible coarse/nanoemulsions alginate as coating containing Zataria multiflora Boiss essential oil (ZEO) on microbial quality fish fillets was investigated at three concentrations (i.e. 0.25%, 0.5% and 1% [w/v]) in 16 days storage 4°C. Moreover, a comparison made between fabricated coarse emulsion nanoemulsion coatings by particle size polydispersity index analyses. Sample analysis performed with regard to total viable count (TVC), psychrophilic (TPC), hydrogen...

Currently, the health benefits of probiotic bacteria are well known, and this has taken up a great deal space in food science health, both research operational. On other hand, anti-biofilm properties on pathogens pharmaceutical industries have created an attractive challenge. This study aimed to describe inhibitory activity cell-free supernatants (CFS), planktonic cells, biofilm form lactobacilus strains (L. rhamnosus L. plantarum) against such as Pseudomonas aeruginosa Listeria...

This study aimed to assess the effects of edible gelatin nanogel coating containing thymol and nisin on inhibition microbial flora inoculated Listeria monocytogenes in fish fillets during a 12-day storage period at temperature 4°C. Data were collected analysed several factors microbiological change, including total viable count, psychrophilic lactic acid bacteria hydrogen sulphide-producing inhibitory determined 3-day intervals. The highest reduction rate (0.95 log CFU/g), (0.92 Hydrogen...

The present study was conducted to investigate the inhibitory effect of alginate coating incorporated with Zataria multiflora Boiss essential oil (ZEO) and lactoperoxidase system (LPOS), individually in combination, order control inoculated Listeria monocytogenes Escherichia coli O157:H7 rainbow trout fillets during 16days storage at 4°C. antibacterial activity ZEO evaluated against E. through determination minimum concentrations (MIC) bactericidal (MBC). In vivo performed by inoculating...

The present study was conducted to determine the characterization and antibacterial activity of peppermint essential oil-loaded solid lipid nanoparticle (PEO-SLN) its impact on quality trout fillet stored at 4 ± 1°C for 12 days. SLNs were prepared through a bath sonication technique. PEO-SLNs contained 0.2% (w/v) PEO in 2% phase glycerol monostearate (GMS) tween 80 (1% w/v) used as surfactant aqueous phase. parameter PEO-SLN evaluated, under vitro conditions. Trout samples analyzed...

Effect of Chitosan Coating Nano-emulsion Containing Zataria multiflora and Bunium persicum Essential Oils on Escherichia Coli O157:H7 in Vacuum-packed Rainbow Trout Fillet

The present study was conducted to evaluate the lipid and protein oxidation responses of cold stored turkey meat using chitosan-contained nanoemulsions supplemented with essential oils two aromatic plants including Zataria multiflora Boiss Bunium persicum Boiss. Chemical traits such as total volatile basic nitrogen (TVB-N), peroxide value (PV), thiobarbituric reactive substances (TBARs), free fatty acids (FFA), acid composition TC (total carbonyl) samples were carried out at 4°C. Moreover,...

Background: The health benefits of probiotic bacteria are not unknown to anyone. On the other hand, indigenous dairy sources a potential source native probiotics. This study aimed describe inhibitory activity Cell-Free Supernatant (CFS), planktonic cells, and biofilm form Lactobacillus strains isolated from on food pathogens. Methods: Antibacterial activities CFS were assessed by microplate method via violet staining, in forms performed spread plate method. Results: results showed that...

The purpose of this preliminary study was to determine the prevalence raw milk contamination with Listeria monocytogenes. In study, 100 bulk tank samples were collected randomly and delivered Pegah Pasteurization Factory in Mashhad. For isolation identification L. monocytogenes, first enriched using cold enrichment method broth, followed by plating onto supplemented Oxford agar. final suspected colonies a multiplex-PCR assay, two pair primers employed. prs are specific for putative...

ABSTRACT The present study is undertaken to predict the effects of Zataria multflora essential oil, NaCl, temperature and pH on probability percentage growth Clostridium botulinum using artificial neural network (ANN). To assess Log P% C. type A spores, experiment was arranged in a factorial design. This design (4 × 3 3) included four levels EO (0.0, 0.015, 0.03 0.06%), three NaCl (0.5, 4 6%), (6, 6.5 7.4), storage temperatures (15, 25 35C) repeated observations (12 times) for BHI broth up...

Coxiella burnetii is the causative agent of zoonotic disease Q fever, and ruminants being considered as main source for human infection. Although route infection in inhalation contaminated aerosols, oral transmission by raw milk or unpasteurized dairy products also a possible Raw produced from may contain virulent C. burnetii. OBJECTIVES: This study aimed to determine contamination rate with METHODS: Touch-down PCR was used examine presence on 147 product samples collected local traditional...

Introduction: This study was conducted to evaluate the influence of chitosan Nano-gel/emulsion coating functionalized by Ziziphora clinopodioides essential oil (ZCEO) and nisin on growth inhibition Escherichia coli O157: H7 inoculated in beef samples during 16 days cold storage condition (4˚C). Methods: Beef sample divided into six groups after inoculation E. O157:H7. Treatments including control (no coating), 2%, sonicated Nano-emulsion containing ZCEO (0.5%), Nano-gel (200 IU/g),...

The Inhibition of Escherichia coli O157:H7 Inoculated in Hamburger Using a Chitosan/Cellulose Nanofiber Film Containing the Nanoemulsion Trachyspermum ammi and Bunium persicum Essential Oils

Abstract Incorporating probiotic bacteria with different biopolymers as edible films is an effective approach to improve their viability. In this study, three (wheat sourdough powder, whole wheat flour, and bovine bone gelatin) are incorporated Lactobacillus plantarum separately the viability of monitored during storage time (40 days at 4 °C) simulated gastrointestinal conditions. The results demonstrated that film has best protective effect on cells film's preparation, (6.5 Log/CFU/g),...
