Bacteriocins in food: evaluation of the factors affecting their effectiveness
(Formatex Research Center, 2013)
Bacteriocins are ribosomally synthesized antibacterial peptides or proteins secreted mainly by lactic acid bacteria. They exhibit activity against food-borne pathogens and are generally recognized as safe compounds. Use ...
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 ...
Potential applications of bacteriocins as bioactive substances for human health
(Nova Science Publishers, 2012)
Lactic acid bacteria are constituents of most of the indigenous microbiota or mucosarelated ecosystems, both in humans or animals. During the last years, many bacteriocins produced by bacteria classified into this group ...
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 ...
Purification techniques of bacteriocins from lactic acid bacteria and other gram-positive bacteria
(Springer, 2011)
The search for new antimicrobial peptides produced by lactic acid bacteria and other Gram-positive microorganisms has become an interesting field of research in the past decades. The fact that bacteriocins are active against ...
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 ...
