Association of a 13.6-Megadalton Plasmid in Pediococcus pentosaceus with Bacteriocin Activity.
Pediococcus pentosaceus FBB61 and L7230, isolated from cucumber fermentations, produced a bacteriocin, designated pediocin A, which had identical activity spectra against species of Pediococcus, Clostridium, Staphylococcus, and Streptococcus. Both strains possessed a 13.6-megadalton plasmid (pMD136). Plasmid curing experiments suggested that both bacteriocin immunity and production determinants...
متن کاملCatabolism of serine by Pediococcus acidilactici and Pediococcus pentosaceus.
The ability to produce diacetyl from pyruvate and l-serine was studied in various strains of Pediococcus pentosaceus and Pediococcus acidilactici isolated from cheese. After being incubated on both substrates, only P. pentosaceus produced significant amounts of diacetyl. This property correlated with measurable serine dehydratase activity in cell extracts. A gene encoding the serine dehydratase...
متن کاملPediocin A modulates intestinal microflora metabolism in swine in vitro intestinal fermentations.
The aim of this study was to investigate in vitro the effects of pediocin A [a bacteriocin produced by lactic acid bacteria (LAB) Pediococcus pentosaceus FBB61] on microbial metabolism in the small and large intestine of pigs. Pediocin A was partially purified by ion exchange chromatography and added to an in vitro fermentation system. The intestinal inoculum was collected from pigs immediately...
متن کاملUse of a bacteriocin produced by Pediococcus acidilactici to inhibit Listeria monocytogenes associated with fresh meat.
A bacteriocin produced by Pediococcus acidilactici had an inhibitory and bactericidal effect on Listeria monocytogenes associated with fresh meat. MICs were significantly lower than minimum killing concentrations. When meat was inoculated with L. monocytogenes, the bacteriocin reduced the number of attached bacteria in 2 min by 0.5 to 2.2 log cycles depending upon bacteriocin concentration. Mea...
متن کاملThe Effect of Pediococcus pentosaceus Bacteriocin on Listeria monocytogenes in Soft Cheese
─Among antimicrobial materials produced by Pediococcus pentosaceus, bacteriocin have gained the greatest interest in food preservation as a natural substance. A bacteriocin producing P. pentosaceus was isolated from vegetables and human stool in a previous study. Purification, activity measurement, and characteristics of the bacteriocin was also determined. The yield of the bacteriocin was 9.08...
