Abstract
Bacteriocins produced by lactic acid bacteria are proteinaceous antibacterial metabolites that normally exhibit bactericidal or bacteriostatic activity against genetically closely related bacteria. In this work, the bacteriocinogenic potential of Pediococcus pentosaceus strain ST58, isolated from oral cavity of a healthy volunteer was evaluated. To better understand the biological role of this strain, its technological and safety traits were deeply investigated through a combined approach considering physiological, metabolomic and genomic properties. Three out of 14 colonies generating inhibition zones were confirmed to be bacteriocin producers and, according to repPCR and RAPD-PCR, differentiation assays, and 16S rRNA sequencing it was confirmed to be replicates of the same strain, identified as P. pentosaceus, named ST58. Based on multiple isolation of the same strain (P. pentosaceus ST58) over the 26 weeks in screening process for the potential bacteriocinogenic strains from the oral cavity of the same volunteer, strain ST58 can be considered a persistent component of oral cavity microbiota. Genomic analysis of P. pentosaceus ST58 revealed the presence of operons encoding for bacteriocins pediocin PA-1 and penocin A. The produced bacteriocin(s) inhibited the growth of Listeria monocytogenes, Enterococcus spp. and some Lactobacillus spp. used to determine the activity spectrum. The highest levels of production (6400 AU/ml) were recorded against L. monocytogenes strains after 24 h of incubation and the antimicrobial activity was inhibited after treatment of the cell-free supernatants with proteolytic enzymes. Noteworthy, P. pentosaceus ST58 also presented antifungal activity and key metabolites potentially involved in these properties were identified. Overall, this strain can be of great biotechnological interest towards the development of effective bio-preservation cultures as well as potential health promoting microbes.

Abstract
Pediococcus pentosaceus isolated from fermented food and the gastrointestinal tracts of humans and animals have been widely identified, and some strains have been reported to reduce inflammation, encephalopathy, obesity and fatty liver in animals. In this study, the genomes of 65 P. pentosaceus strains isolated from human and animal feces and different fermented food were sequenced and comparative genomics analysis was performed on all strains along with nine sequenced representative strains to preliminarily reveal the lifestyle of P. pentosaceus, and investigate the genomic diversity within this species. The results reveal that P. pentosaceus is not host-specific, and shares core genes encoding proteins related to translation, ribosomal structure and biogenesis and signal transduction mechanisms, while its genetic diversity relates mainly to carbohydrate metabolism, and horizontally transferred DNA, especially prophages and bacteriocins encoded on plasmids. Additionally, this is the first report of a type IIA CRISPR/Cas system in P. pentosaceus. This work provides expanded resources of P. pentosaceus genomes, and offers a framework for understanding the biotechnological potential of this species.

Abstract
Background Lactic acid bacteria (LAB) are a diverse group of Gram-positive bacteria, which are widely distributed in various diverse natural habitats. These are used in a variety of industrial food fermentations and carry numerous traits with utmost relevance to the food industry. Genetic engineering has emerged as an effective means to improve and enhance the potential of commercially important bacterial strains. However, the biosafety of recombinant systems is an important concern during the implementation of such technologies on an industrial scale. In order to overcome this issue, cloning and expression systems have been developed preferably from fully characterized and annotated LAB plasmids encoding genes with known functions. Results The developed shuttle vector pPBT-GFP contains two theta-type replicons with a copy number of 4.4 and 2.8 in Pediococcus acidilactici MTCC 5101 and Lactobacillus brevis MTCC 1750, respectively. Antimicrobial “pediocin” produced by P. acidilactici MTCC 5101 and green fluorescent protein (GFP) of Aequorea victoria were successfully expressed as selectable markers. Heterologous bile salt hydrolase (BSH) from Lactobacillus fermentum NCDO 394 has been efficiently expressed in the host strains showing high specific activity of 126.12 ± 10.62 in P. acidilactici MTCC 5101 and 95.43 ± 4.26 in the case of L. brevis MTCC 1750, towards glycine-conjugated bile salts preferably as compared to taurine-conjugated salts. Conclusion The present article details the development of a LAB/LAB shuttle expression vector pPBT-GFP, capable of replication in LAB hosts, P. acidilactici MTCC 5101, and L. brevis MTCC 1750. Pediocin and GFP have been used as selectable markers with the efficient production of heterologous extracellular bile salt hydrolase. Thus, the constructed vector pPBT-GFP, with its ability to replicate in multiple hosts, low copy number, and stability in host cells, may serve as an ideal tool for improving LAB strains of commercial value using genetic engineering.

Abstract
Lactobacillus pentosus F03, a strain isolated from pig intestines in Taiwan, contains multiple endogenous plasmids. We isolated, completely sequenced, and characterized five of the plasmids present in L. pentosus F03 designated as pF03-1 (3282bp), pF03-2 (3293bp), pF03-3 (1787bp), pF03-4 (2138bp), and pF03-5 (1949bp). The replication types of these plasmids were predicted by comparing the features of the replicon nucleotides and the similarity of replication proteins with those of the plasmids of known replication types. The results of basic local alignment search tool analyses indicate that these plasmids, except for pF03-4, belong to different replicating plasmid families. According to replicon and initiator protein analyses, pF03-1, pF03-2, and pF03-3, were determined to belong respectively to the pMV158, pC194/pUB110, and pT181 families of rolling-circle replication plasmids. However, pF03-5 contains the typical features observed in the family of theta-replicating plasmids and belongs to the pUCL287 family of theta-replicating plasmids.

Plasmid 2014; 77:28-31.

Abstract
A chimeric plasmid, pRS7Rep (6.1 kb), was constructed using the replication region of pRS7, a large plasmid from Oenococcus oeni, and pEM64, a plasmid derived from pIJ2925 and containing a gene for resistance to chloramphenicol. pRS7Rep is a shuttle vector that replicates in Escherichia coli using its pIJ2925 component and in lactic acid bacteria (LAB) using the replication region of pRS7. High levels of transformants per µg of DNA were obtained by electroporation of pRS7Rep into Pediococcus acidilactici (1.5 × 10(7)), Lactobacillus plantarum (5.7 × 10(5)), Lactobacillus casei (2.3 × 10(5)), Leuconostoc citreum (2.7 × 10(5)), and Enterococcus faecalis (2.4 × 10(5)). A preliminary optimisation of the technical conditions of electrotransformation showed that P. acidilactici and L. plantarum are better transformed at a later exponential phase of growth, whereas L. casei requires the early exponential phase for better electrotransformation efficiency. pRS7Rep contains single restriction sites useful for cloning purposes, BamHI, XbaI, SalI, HincII, SphI and PstI, and was maintained at an acceptable rate (>50%) over 100 generations without selective pressure in L. plantarum, but was less stable in L. casei and P. acidilactici. The ability of pRS7Rep to accept and express other genes was assessed. To the best of our knowledge, this is the first time that the replication region of a plasmid from O. oeni has been used to generate a cloning vector.

Abstract
AIMS This study was designed to isolate and characterize the lactic acid microbiota of the musts and wines of a young denomination of origin area, Ribeira Sacra in north-west Spain. METHODS AND RESULTS Over three consecutive years (2007, 2008 and 2009), we examined musts and wines from four cellars in different zones of the region. Through biochemical and genetic tests, 459 isolates of lactic acid bacteria (LAB) were identified as the following species: Lactobacillus alvei (0·7%), Lactobacillus brevis (1·7%), Lactobacillus frumenti (0·9%), Lactobacillus kunkeei (12%), Lactobacillus plantarum (6·5%), Lactobacillus pentosus (0·9%), Lactococcus lactis ssp. lactis (3%), Leuconostoc citreum (0·7%), Leuconostoc fructosum (synon. Lactobacillus fructosum) (3·7%), Leuconostoc mesenteroides ssp. mesenteroides (2·8%), Leuconostoc pseudomesenteroides (0·2%), Oenococcus oeni (59%), Pediococcus parvulus (7%) and Weisella paramesenteroides (synon. Leuconostoc paramesenteroides) (0·9%). Of these species, O. oeni was the main one responsible for malolactic fermentation (MLF) in all cellars and years with the exception of Lact. plantarum, predominant in 2007, in one cellar, and Lact. brevis, Lact. frumenti and Ped. parvulus coexisting with O. oeni in one cellar in 2009. Different strains (84) of LAB species (14) were identified by biochemical techniques (API strips, the presence of plasmids, enzyme activities and MLF performance) and molecular techniques (PCR). All assays were carried out with every one of the 459 isolates. To select candidates for use as culture starters, we assessed malolactic, β-glucosidase and tannase activities, the presence of genes involved in biogenic amine production and plasmid content. CONCLUSIONS A high diversity of LAB is present in the grape musts of Ribeira Sacra but few species are responsible for MLF; however, different strains of such species are involved in the process. As far as we are aware, this is the first report of Lact. frumenti thriving in wine. SIGNIFICANCE AND IMPACT OF THE STUDY Information on LAB populations in must and wine is presented. A large collection of well-characterized strains of LAB are available as starter cultures to winemakers.
