Strains of the food-borne pathogenListeria monocytogenes, showing either intermediate or high-level resistance to class IIa bacteriocins, were investigated to determine characteristics that correlated with their sensitivity levels. Two intermediate a

Bacteriocin-producing starter cultures have been suggested as natural food preservatives; however, development of resistance in the target organism is a major concern. We investigated the development of resistance in Listeria monocytogenes to the two

A concern regarding the use of bacteriocins, as for example the lantibiotic nisin, for biopreservation of certain food products is the possibility of resistance development and potential cross-resistance to antibiotics in the target organism. The gen

Bacteriocin inactivation of Listeria monocytogenes 412 was studied as a function of growth phase. Cells were treated with nisin (300 IU ml−1) or pediocin (320 or 2560 AU ml−1) for 20 min at 30 °C. Inactivation with nisin or the low concentration

Pediocin PA-1, which is a bacteriocin produced by lactic acid bacteria, has potential as a biopreservative of food. However, such use may lead to the development of resistance in the target organism. Gene expression in two independent pediocin-resist

Forty-eight strains of Listeria monocytogenes were genotyped by two rapid methods: random amplification of polymorphic DNA (RAPD) and 16S to 23S rRNA internal transcribed spacer fragment length polymorphism (ITS), and compared to the more time-consum

Sublethal concentrations of ethanol or isopropanol increased attachment of Listeria monocytogenes at 10, 20, or 30°C; no induction occurred at 37°C. The alcohol induction phenotype was retained in sigB and cesRK mutants; however, the degree of indu

Aims: This study elucidates the mechanisms by which a nonbacteriocinogenic Carnobacterium piscicola inhibits growth of Listeria monocytogenes. Methods and Results: Listeria monocytogenes was exposed to live cultures of a bacteriocin-negative variant
