(Natural News) Researchers from the University College Cork made a startling discovery: Western diets – a diet comprising empty carbs, junk food, red meats, and foods high in saturated fat – can increase the risk of being infected by the foodborne pathogen, Listeria monocytogenes.  In their report, which appeared in the most recent edition of Microbiome, the scientists revealed that high-fat...

In this study, a systematic approach was used for the improved identification of novel LAB strains able to exert antagonistic effect against important foodborne pathogens. Our findings suggest that the selected panel of LAB probiotic strains can be used as biocontrol cultures to inhibit and/or reduce the growth of L. monocytogenes, Salmonella, and E. coli O157:H7 in different matrices, and environments.

Antibacterial activity of all examined postbiotics was mainly associated to pyrrolo [1,2-a] pyrazine-1,4-dione and somewhat to the presence of different organic acids. Postbiotics of all Lactobacillus spp. maintained thier residual antimicrobial activity over 50% at different pH lev...

Miller, Youngsoo LeeAbstractNisin-loaded zein microcapsules were prepared in a microfluidic chip using an internal phase separation method. The release profiles of nisin from the microcapsules were modified by varying nisin loading and flow rate during the microfluidic process. Rapid release of nisin was achieved with low flow rate in dispersed phase (0.2 ml/h) and high loading (9.67–12.64 μg/mg) of nisin in the microcapsule, while slow release of nisin was achieved with hig...

The models were assessed using the adjusted determination coefficient (adj-R2) and the root mean square error (RMSE). Then, Ward's cluste...

Abstract In the present research the effect of incorporating cinnamon essential oil (CEO), oleic acid (OA) and glutaraldehyde (GL) on antimicrobial, antioxidant, mechanical, physical and morphological properties of chitosan-carboxymethyl cellulose composite films were investigated. Cross-linking effect of GL (as determined by FTIR analysis) significantly resulted in higher mechanical strength and lower water vapor permeability (WVP). Cross-linked films incorporated with CEO revealed higher and steady state antioxidant activity as well as in vitro antimicrobial properties against Listeria monocytogenes and Pseudomo...

Abstract Listeria monocytogenes is a gram-positive, facultative anaerobic, motile bacillus widely spread in the environment. However, clinical infection in humans is uncommon. The route of infection is often through ingestion of raw vegetables, meat and unpasteurised dairy products. Listeria is an uncommon cause of meningitis in immunocompetent individuals, but it should be considered strongly in neonates and the elderly, and it should also be considered in those with impaired cell-mediated immunity. 1 , 2 Only a few case reports of invasive listeriosis in humans have been reported from India. 3 - 8 In our case, a...

Abstract Background: Kiwifruit (Actinidia chinensis) peel has been always considered as useless because of the harsh taste. To promote the full utilization of kiwifruit resources it is essential to explore the nutritional benefits of kiwifruit peel. Objective: Our studies explored the difference in polyphenolic composition and biological activity including antioxidant, antimicrobial, and antiproliferative activity of the flesh and peel of kiwifruit. Design: Antioxidant activity of the extracted polyphenols of the peel and flesh of A. chinensis was checked by 2,2-diphenyl-1-picrylhydrazyl, 2,2'-azino-bis3...

Abstract Foodborne pathogens pose one of the greatest challenges facing public health in the modern day. One important pathogen, Listeria monocytogenes, is known to be challenging to detect and identify. Three serovars cause most of the Listeria related food-borne illnesses, which the Centers for Disease Control currently utilizes a combination of pulsed-field gel electrophoresis and whole genome sequencing for identification and the determination of clusters and outbreaks. There is a potential method for rapid collection of epidemiological information by exploiting the electrokinetic and dielectrophoretic propert...
