Biochemical, antimicrobial and molecular characterization of a noncytotoxic bacteriocin produced by Lactobacillus plantarum ST71KS
(Academic Press Ltd - Elsevier Science Ltd, 2013-06-28)
Lactobacillus (Lb.) plantarum ST71KS was isolated from homemade goat feta cheese and identified using biochemical and molecular biology techniques. As shown by Tricine-SDS-PAGE, this lactic acid bacterium produces a ...
Inhibitory Effect of the Hybrid Bacteriocin Ent35-MccV on the Growth of Escherichia coli and Listeria monocytogenes in Model and Food Systems
(Springer, 2015-01-24)
Bacteriocins are being used as new food biopreservative agents. In general, bacteriocins produced by Gram-positive bacteria are active against other Grampositive. Basically, the same principle applies to those produced ...
PrfA activation in Listeria monocytogenes increases the sensitivity to class IIa bacteriocins despite impaired expression of the bacteriocin receptor
(Elsevier B.V., 2019-08)
Background: The scope of the present work was to characterize the activity of class IIa bacteriocins in Listeria (L.) monocytogenes cells that constitutively express an activated form of PrfA, the virulence master regulator, ...
Adsorption of the bacteriocins produced by Lactobacillus curvatus CRL705 on a multilayer-LLDPE film for food-packaging applications
(Elsevier, 2013-01)
Adsorption of bacteriocins produced by Lactobacillus curvatus CRL705, lactocin 705 (whose activity depends upon complementation of two peptides, lac705α and lac705β) and bacteriocin/s with strong anti-Listeria activity, ...
Silicates characterization as potential bacteriocin-carriers
(Elsevier, 2010-01)
Two different silicates, zeosil and expanded perlite, were characterized as potential carriers of a bacteriocin with anti-Listeria monocytogenes activity, produced by Enterococcus faecium CRL1385. Specific surface areas ...
Gram-positive bacteriocins: usage as antimicrobial agents in veterinary medicine
(Springer, 2020-07)
Antimicrobial resistance is a worldwide spread phenomenon that affects both human and veterinary medicine. This issue has led to a “One Health” approach in order to coordinate efforts and set back the development of ...
Characterization of the bacteriocins and the PrtR regulator in a plant-associated Pseudomonas strain
(Elsevier Science, 2020-01-10)
The emergence of antibiotic resistant bacterial strains demands the development of new antimicrobial agents. In the last decades, bacteriocins have gained significant interest due to their potential application as ...
Characterization of the bacteriocins and the PrtR regulator in a plant-associated Pseudomonas strain
(Elsevier Science, 2020-01)
The emergence of antibiotic resistant bacterial strains demands the development of new antimicrobial agents. In the last decades, bacteriocins have gained significant interest due to their potential application as ...
Potential use of a bacteriocin-like substance in meat and vegetable food biopreservation
(Universiti Putra Malaysia. Faculty of Food Science & Technology, 2014-05)
Bacillus spp. produces a large number of antimicrobial peptides and includes a variety of species of industrial importance. The aim of the present study was to evaluate the shelf-life extension of fresh beef and lettuce ...
A ptsP deficiency in PGPR Pseudomonas fluorescens SF39a affects bacteriocin production and bacterial fitness in the wheat rhizosphere
(Elsevier Science, 2016-04)
Pseudomonas fluorescens SF39a is a plant-growth-promoting bacterium isolated from wheat rhizosphere. In this report, we demonstrate that this native strain secretes bacteriocins that inhibit growth of phytopathogenic strains ...
