Disease relevance of Pediococcus

• Considerable advances have been made in the genetics and molecular biology of lactic acid bacteria, including Lactococcus, Lactobacillus, Leuconostoc, Pediococcus and Streptococcus spp [1].
• The N-terminal truncated E. coli enzyme, with a 21 amino acid region removed, is similar in size to the Pediococcus pentosaceus glutamate racemase [2].
• When transferred into Lactococcus lactis and Pediococcus acidilactici strains, aga modified the sugar fermentation profile of the strains from melibiose negative (Mel(-)) to melibiose positive (Mel(+)) [3].
• Modification of peptidoglycan precursors is a common feature of the low-level vancomycin-resistant VANB-type Enterococcus D366 and of the naturally glycopeptide-resistant species Lactobacillus casei, Pediococcus pentosaceus, Leuconostoc mesenteroides, and Enterococcus gallinarum [4].
• The ORF1 sequence showed strong amino-acid sequence identity to a recently identified putative ORF1 protein of a cryptic Hp plasmid, pHPM180, and significant homologies to putative Rep proteins of Campylobacter coli (RepB) and Pediococcus halophilus (RepA), and was therefore designated RepA [5].

High impact information on Pediococcus

• Two other strains did not belong to any previously described 16S rRNA group of LAB and occupied an intermediate position between the L. casei/Pediococcus group and the Weissella group and species of Carnobacterium [6].
• The gene encoding D-lactate dehydrogenase was isolated on a 2.9-kb insert from a library of Pediococcus acidilactici DNA by complementation for growth under anaerobiosis of an Escherichia coli lactate dehydrogenase and pyruvate-formate lyase double mutant [7].
• A total of 18 Ped-2B2-reactive Pediococcus spp. isolates were isolated from eight food samples and assayed for bacteriocin production [8].
• Pediococcus halophilus X-160 which lacks catabolite control by glucose was isolated from nature (soy moromi mash) [9].
• Correlation between depression of catabolite control of xylose metabolism and a defect in the phosphoenolpyruvate:mannose phosphotransferase system in Pediococcus halophilus [9].

Chemical compound and disease context of Pediococcus

• A Pediococcus cerevisiae mutant that actively accumulated folate (PteGlu), in contrast to the wild-type, was also found to exhibit changes in the pattern of uptake of 5-methyl-tetrahydrofolate (5-CH3-H4PteGlu) and amethopterin [10].
• Production of racemic lactic acid in Pediococcus cerevisiae cultures by two lactate dehydrogenases [11].
• The lactate is stoichiometrically converted to pyruvate and hydrogen peroxide by lactate oxygen oxidoreductase derived from Pediococcus species [12].
• Physiological and enzymatic properties of a thymidine-requiring Pediococcus cerevisiae mutant [13].
• The Pediococcus pentosaceus glutamate racemase gene product complemented the D-glutamate auxotrophy of Escherichia coli WM335 [14].

Biological context of Pediococcus

• A second flavin pyruvate oxidase from Pediococcus pseudomonas (POXPP), which catalyzes the oxidative decarboxylation of pyruvate to CO2 and acetyl phosphate, also requires FAD for acetoin formation [15].
• AIMS: The possibility of substrate inhibition by glucose on biomass and pediocin production was studied in cultures of Pediococcus acidilactici on a residual medium [16].
• The effects of treatment with an undefined commercial Nurmi-type culture (NTC), cultured cecal contents, and a dual-strain probiotic, containing Enterococcus faecalis and Pediococcus pentosaceus, on Salmonella Typhimurium colonization were evaluated in a specific-pathogen-free bird model [17].
• Plasmids derived from pRS4 containing the chloramphenicol resistance gene were successfully electrotransformed in L. plantarum, L. casei, P. pentosaceus, and Pediococcus acidilactici, suggesting that pRS4 could be used as a cloning vector for lactic acid bacteria [18].
• Optimization of the culture medium for growth and the kinetics of lactate fermentation by Pediococcus sp. ISK-1 [19].

Anatomical context of Pediococcus

• Hydrolysates of cod viscera were tested as an alternative to commonly used complex nitrogen sources (peptones and/or extracts) for the type strains of the lactic acid bacteria Lactococcus lactis, Lactobacillus acidophilus, Lactobacillus helveticus, Lactobacillus casei, Lactobacillus sakei and Pediococcus pentosaceus [20].
• Overproduction of glutamate racemase of Pediococcus pentosaceus in Escherichia coli clone cells and its purification [21].

Gene context of Pediococcus

• A putative glucan synthase gene dps detected in exopolysaccharide-producing Pediococcus damnosus and Oenococcus oeni strains isolated from wine and cider [22].
• In this study, the malolactic gene from Pediococcus damnosus NCFB1832 (mleD) was cloned into S. cerevisiae and co-expressed with the malate permease gene (mae1) of Schizosaccharomyces pombe [23].
• Pediocin A, a bacteriocin produced by Pediococcus pentosaceus FBB61 [24].
• Rapid purification, partial characterization, and antimicrobial spectrum of the bacteriocin, Pediocin AcM, from Pediococcus acidilactici M [25].
• Detection and quantification of Brettanomyces bruxellensis and 'ropy' Pediococcus damnosus strains in wine by real-time polymerase chain reaction [26].

Analytical, diagnostic and therapeutic context of Pediococcus

• The bacteriocin from Pediococcus acidilactici M, designated as Pediocin AcM, was rapidly purified to homogeneity by the pH mediated cell adsorption-desorption method and semi-preparative reversed-phase HPLC [25].
• Enzyme electrode composed of the pyruvate oxidase from Pediococcus species coupled to an oxygen electrode for measurements of pyruvate in biological media [27].
