Plasmid-Associated Bacteriocin Production and Sucrose Fermentation in Pediococcus acidilactici.
Production of bacteriocin activity designated pediocin PA-1 was associated with the presence of a 6.2-megadalton plasmid in Pediococcus acidilactici PAC1.0. The bacteriocin exhibited activity against P. acidilactici, P. pentosaceus, Lactobacillus plantarum, L. casei, L. bifermentans, and Leuconostoc mesenteroides subsp. dextranicum. Partial characterization of pediocin PA-1 is described. The mo...
متن کاملOptimized 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 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 کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Pediocin production by Pediococcus acidilactici in solid state culture on a waste medium: process simulation and experimental results.
The production of pediocin by Pediococcus acidilactici was comparatively studied in submerged and solid-state culture, using polyurethane foam particles soaked in commercial (MRS) and waste media with various supplements, where product concentrations were 15 times higher in MRS medium. For the solid state analysis, cultures were treated by successive compression and refilling of tubular minirea...
