Optimized culture conditions for bacteriocin production by Pediococcus acidilactici LAB 5 and its characterization.
A strain of Pediococcus acidilactici LAB 5 was isolated from vacuum-packed fermented meat product, in order to obtain a novel bacteriocin from food-grade organisms. Optimized culture conditions for bacteriocin production in different media (viz., MRS, TGE, TGE + buffer, TGE + Tween 80, and TGE + Tween 80 + buffer) and at different temperatures and pH conditions were reported. TGE + Tween 80 + b...
متن کاملDraft Genome Sequence of the Pediocin-Encoding Biopreservative and Biocontrol Strain Pediococcus acidilactici D3
We describe a draft genome sequence for Pediococcus acidilactici strain D3, a component of multistrain commercial cultures with biopreservative and biocontrol properties in food-based applications. Strain D3 encodes at least one antimicrobial peptide, pediocin AMPd3. The AMPd3-encoding operon exhibits high sequence similarity to the archetype pediocin, PA-1, encoded by P. acidilactici PAC 1.0.
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 PA-1, a bacteriocin from Pediococcus acidilactici PAC1.0, forms hydrophilic pores in the cytoplasmic membrane of target cells.
Pediocin PA-1 is a bacteriocin which is produced by Pediococcus acidilactici PAC1.0. We demonstrate that pediocin PA-1 kills sensitive Pediococcus cells and acts on the cytoplasmic membrane. In contrast to its lack of impact on immune cells, pediocin PA-1 dissipates the transmembrane electrical potential and inhibits amino acid transport in sensitive cells. Pediocin interferes with the uptake o...
متن کاملDetection of the pediocin gene pedA in strains from human faeces by real-time PCR and characterization of Pediococcus acidilactici UVA1
BACKGROUND Bacteriocin-producing lactic acid bacteria are commonly used as natural protective cultures. Among them, strains of the genus Pediococcus are particularly interesting for their ability to produce pediocin, a broad spectrum antimicrobial peptide with a strong antagonistic activity against the food-borne pathogen Listeria monocytogenes. Furthermore, there is increasing interest in isol...
