Bacteriocins: safe, natural antimicrobials for food preservation.
Bacteriocins are antibacterial proteins produced by bacteria that kill or inhibit the growth of other bacteria. Many lactic acid bacteria (LAB) produce a high diversity of different bacteriocins.Expand

Nisin Resistance in Listeria monocytogenes ATCC 700302 Is a Complex Phenotype
ABSTRACT Nisin resistance in Listeria monocytogenes ATCC 700302 is a complex phenotype involving alterations in both the cytoplasmic membrane and the cell wall and a requirement for divalent cations.Expand

Inhibition of food-borne bacterial pathogens by bacteriocins from lactic acid bacteria isolated from meat.
Ten strains of bacteriocin-producing lactic acid bacteria were isolated from retail cuts of meat. These 10 strains along with 11 other bacteriocin-producing lactic acid bacteria were tested forExpand

Depletion of proton motive force by nisin in Listeria monocytogenes cells.
The basal proton motive force (PMF) levels and the influence of the bacteriocin nisin on the PMF were determined in Listeria monocytogenes Scott A. In the absence of nisin, the interconversion of theExpand

Mechanistic action of pediocin and nisin: recent progress and unresolved questions
Abstract Nisin and pediocin PA-1 are examples of bacteriocins from lactic acid bacteria (LAB) that have found practical applications as food preservatives. Like other natural antimicrobial peptides,Expand

Electrostatic interactions, but not the YGNGV consensus motif, govern the binding of pediocin PA-1 and its fragments to phospholipid vesicles.
The purpose of this study was to characterize in detail the binding of pediocin PA-1 and its fragments to target membranes by using tryptophan fluorescence as a probe. Based on a three-dimensionalExpand

Functional characterization of pediocin PA-1 binding to liposomes in the absence of a protein receptor and its relationship to a predicted tertiary structure.
The physicochemical interaction of pediocin PA-1 with target membranes was characterized using lipid vesicles made from the total lipids extracted from Listeria monocytogenes. Pediocin PA-1 causedExpand

Nisin induces changes in membrane fatty acid composition of Listeria monocytogenes nisin‐resistant strains at 10°C and 30°C
Listeria monocytogenes isolates resistant to 105 IU ml‐1 nisin were obtained at 30°C (NR30) and at 10°C (NR10). Nisin prolonged the lag phase of isolate NR30 at 10°C. Isolates NR30 and NR10 did notExpand

Carbon Dioxide and Nisin Act Synergistically onListeria monocytogenes
ABSTRACT This paper examines the synergistic action of carbon dioxide and nisin on Listeria monocytogenes Scott A wild-type and nisin-resistant (Nisr) cells grown in broth at 4°C. Carbon dioxideExpand
