Abstract
Oenococcus oeni is the lactic acid bacteria species most commonly encountered in wine, where it develops after the alcoholic fermentation and achieves the malolactic fermentation that is needed to improve the quality of most wines. O. oeni is abundant in the oenological environment as well as in apple cider and kombucha, whereas it is a minor species in the natural environment. Numerous studies have shown that there is a great diversity of strains in each wine region and in each product or type of wine. Recently, genomic studies have shed new light on the species diversity, population structure, and environmental distribution. They revealed that O. oeni has unique genomic features that have contributed to its fast evolution and adaptation to the enological environment. They have also unveiled the phylogenetic diversity and genomic properties of strains that develop in different regions or different products. This review explores the distribution of O. oeni and the diversity of strains in natural habitats.

Abstract
AIMS Oenococcus oeni is the lactic acid bacteria species which is the most adapted to wine. Recently, two groups of strains that form two genetic lineages were described in red and white Burgundy wines. The aim of this study was to analyse the phenotypes of these strains in order to determine how they have adapted specifically to either red or white wine. METHODS AND RESULTS Four strains from each group were tested in grape must and in wines to evaluate their tolerance to pH and to phenolic compound content. White wine strains proved to be the most tolerant to low pH, both in grape must and in wine, whereas they were inhibited by the presence of grape tannins in wine. Red wine strains were more sensitive to acidity, but very resistant to phenolic compounds. CONCLUSIONS The results suggest that pH and phenolic compounds drive strain selection at several stages of wine production. SIGNIFICANCE AND IMPACT OF THE STUDY Although it is well known that O. oeni is well adapted to wine, this study shows that strains of some genetic lineages within this species have evolved to adapt better than others to specific types of wines.

Abstract
Oenococcus oeni is the main lactic acid bacteria species associated with grapes and wine. It is a bacterium that has adapted itself to the harsh conditions of wine, and demonstrated its importance in the production of quality wines. It has a small genome (1.8 Mb); over 200 strains have had their genome sequenced. Genomic analyses have proposed that there are two major branches of O. oeni strains that might be linked to wine style (sparkling wine versus white and red) and metagenomic studies have suggested a possible influence of terroir. This review explores recent developments of O. oeni including genomic studies examining O. oeni diversity and how this might shape future regional-specific commercial O. oeni starter strains.

Abstract
Oenococcus oeni is the dominant species able to cope with a hostile environment of wines, comprising cumulative effects of low pH, high ethanol and SO2 content, nonoptimal growth temperatures and growth inhibitory compounds. Ethanol tolerance is a crucial feature for the activity of O. oeni cells in wine because ethanol acts as a disordering agent of its cell membrane and negatively affects metabolic activity; it damages the membrane integrity, decreases cell viability and, as other stress conditions, delays the start of malolactic fermentation with a consequent alteration of wine quality. The cell wall, cytoplasmic membrane and metabolic pathways are the main sites involved in physiological changes aimed to ensure an adequate adaptive response to ethanol stress and to face the oxidative damage caused by increasing production of reactive oxygen species. Improving our understanding of the cellular impact of ethanol toxicity and how the cell responds to ethanol stress can facilitate the development of strategies to enhance microbial ethanol tolerance; this allows to perform a multidisciplinary endeavour requiring not only an ecological study of the spontaneous process but also the characterization of useful technological and physiological features of the predominant strains in order to select those with the highest potential for industrial applications.

Biogeography of Oenococcus oeni Reveals Distinctive but Nonspecific Populations in Wine-Producing Regions. Appl Environ Microbiol 2017; 83:AEM.02322-16.

Abstract
Understanding the mechanisms behind the typicity of regional wines inevitably brings attention to microorganisms associated with their production. Oenococcus oeni is the main bacterial species involved in wine and cider making. It develops after the yeast-driven alcoholic fermentation and performs the malolactic fermentation, which improves the taste and aromatic complexity of most wines. Here, we have evaluated the diversity and specificity of O. oeni strains in six regions. A total of 235 wines and ciders were collected during spontaneous malolactic fermentations and used to isolate 3,212 bacterial colonies. They were typed by multilocus variable analysis, which disclosed a total of 514 O. oeni strains. Their phylogenetic relationships were evaluated by a second typing method based on single nucleotide polymorphism (SNP) analysis. Taken together, the results indicate that each region holds a high diversity of strains that constitute a unique population. However, strains present in each region belong to diverse phylogenetic groups, and the same groups can be detected in different regions, indicating that strains are not genetically adapted to regions. In contrast, greater strain identity was seen for cider, white wine, or red wine of Burgundy, suggesting that genetic adaptation to these products occurred. IMPORTANCE This study reports the isolation, genotyping, and geographic distribution analysis of the largest collection of O. oeni strains performed to date. It reveals that there is very high diversity of strains in each region, the majority of them being detected in a single region. The study also reports the development of an SNP genotyping method that is useful for analyzing the distribution of O. oeni phylogroups. The results show that strains are not genetically adapted to regions but to specific types of wines. They reveal new phylogroups of strains, particularly two phylogroups associated with white wines and red wines of Burgundy. Taken together, the results shed light on the diversity and specificity of wild strains of O. oeni, which is crucial for understanding their real contribution to the unique properties of wines.

Abstract
Different lactic acid bacteria strains have been shown to cause wine spoilage, including the generation of substances undesirable for the health of wine consumers. The aim of this study was to investigate the occurrence of selected species of heterofermentative lactobacilli, specifically Lactobacillus brevis, Lactobacillus hilgardii, and Lactobacillus plantarum in six different Slovak red wines following the fermentation process. In order to identify the dominant Lactobacillus strain using quantitative (real time) polymerized chain reaction (qPCR) method, pure lyophilized bacterial cultures from the Czech Collection of Microorganisms were used. Six different red wine samples following malolactic fermentation were obtained from selected wineries. After collection, the samples were subjected to a classic plate dilution method for enumeration of lactobacilli cells. Real-time PCR was performed after DNA extraction from pure bacterial strains and wine samples. We used SYBR® Green master mix reagents for measuring the fluorescence in qPCR. The number of lactobacilli ranged from 3.60 to 5.02 log CFU mL(-1). Specific lactobacilli strains were confirmed by qPCR in all wine samples. The number of lactobacilli ranged from 10(3) to 10(6) CFU mL(-1). A melting curve with different melting temperatures (T(m)) of DNA amplicons was obtained after PCR for the comparison of T(m) of control and experimental portions, revealing that the most common species in wine samples was Lactobacillus plantarum with a T(m) of 84.64°C.

Abstract
Oenococcus oeni is responsible for the malolactic fermentation of wine. Genomic diversity has already been established in this species. In addition, winemakers usually report varying starter-culture efficiency. It is essential to monitor indigenous and selected strains in order to understand strain survival and development during the winemaking process. A previous article described a variable number of tandem repeats (VNTR) scheme, based on five polymorphic loci of the genome. VNTR typing of O. oeni was highly discriminating, faster, and more reliable than the PFGE or MLST methods. The objective of this study was to set up a faster protocol by multiplexing, taking advantage of the high performance of multicolor capillary electrophoresis. The primers were labeled with multiple fluorescent dyes. PCR conditions were adapted by multiplexing amplifications in two separate PCR mixtures for the five loci, both at the same annealing temperature. The resulting assay proved to be robust, accurate, fast and easy to perform. Thanks to this new protocol, all O. oeni strains used in the study were typed using the five tandem repeats (TR). As expected, the primers for the five TR loci were specific to O. oeni. The method was improved to analyze isolated and mixed colonies, as well as bacteria harvested from wine using fast technology for analysis of nucleic acids (FTA(®)) technology. Finally, predictive models were constructed, to predict phylogenetic relationships and associate bacterial strain resistance to freeze-drying with fragment length analysis (FLA) profiles and genotypic and phenotypic characters.

Abstract
The microflora of must and wine consists of yeasts, acetic acid bacteria and lactic acid bacteria (LAB). The latter group plays an important role for wine quality. The malolactic fermentation carried out by LAB leads to deacidification and stabilisation of wines. Nevertheless, LAB are often associated with wine spoilage. They are mainly responsible for the formation of biogenic amines. Furthermore, some strains produce exopolysaccharide slimes, acetic acid, diacetyl and other off-flavours. In this context a better monitoring of the vinification process is crucial to improve wine quality. Moreover, a lot of biodiversity studies would also profit from a fast and reliable identification method. In this study, we propose a species-specific multiplex PCR system for a rapid and simultaneous detection of 13 LAB species, frequently occurring in must or wine: Lactobacillus brevis, Lb. buchneri, Lb. curvatus, Lb. hilgardii, Lb. plantarum, Leuconostoc mesenteroides, Oenococcus oeni, Pediococcus acidilactici, P. damnosus, P. inopinatus, P. parvulus, P. pentosaceus and Weissella paramesenteroides.

Abstract
AIMS To investigate the Oenococcus oeni population occurring during spontaneous malolactic fermentation (MLF) of Amarone wine, a peculiar and hostile environment for malolactic bacteria. METHODS AND RESULTS Pulsed-field gel electrophoresis (PFGE) analysis showed a high level of genetic heterogeneity within the O. oeni population involved in MLF throughout an industrial vinification of Amarone wine. The 13 strains with distinct PFGE profile displayed different capability to hydrolyse esters and glycosides, as well as great variability to growth under stress parameters, such as high ethanol content (15% v/v), low pH (3·0) and temperature (15°C), and presence of SO(2). Moreover, polymorphism in the gene sacB involved in exopolysaccharide production was observed among the strains. The strains showed differences to convert l-malic acid into l-lactic acid in wine. CONCLUSIONS The occurrence of spontaneous MLF in stressful ecosystems such as Amarone wine is related to the heterogeneity of O. oeni community; biodiversity indexes and strain evolution analyses suggested that its success depends on its initial strain evenness. SIGNIFICANCE AND IMPACT OF THE STUDY Remarkable intraspecies complexity within the O. oeni natural population could explain the great versatility of this species as key of successful adaptation to harsh winemaking conditions.

Abstract
Ecology of the lactic acid bacteria (LAB) during alcoholic fermentation (AF) and spontaneous malolactic fermentation (MLF) of Tempranillo wines from four wineries of La Rioja has been studied analyzing the influence of the winemaking method, processing conditions, and geographical origin. Five different LAB species were isolated during AF, while, during MLF, only Oenococcus oeni was detected. Although the clonal diversity of O. oeni strains was moderate, mixed populations were observed, becoming at least one strain with distinct PFGE profile the main responsible for MLF. Neither the winemaking method nor the cellar situation was correlated with the LAB diversity. However, processing conditions influenced the total number of isolates and the percentage of each isolated species and strains. The winemaking method could cause that genotypes found in semicarbonic maceration did not appear in other wineries. Four genotypes of O. oeni were isolated in more than one of the rest wineries. These four together with other dominant strains might be included in a future selection process.

Abstract
Diversity of lactic acid bacteria (LAB) species has been analyzed for three consecutive years (2006, 2007, and 2008) during alcoholic and malolactic fermentations of Tempranillo wine in a winery at La Rioja. The results showed differences in malolactic fermentation duration, and in both diversity of LAB species and diversity of Oenococcus oeni genotypes. O. oeni was shown to be the predominant species (73% of total isolates). Monitoring the different strains of O. oeni using pulsed-field gel electrophoresis of chromosomal DNA digested with SfiI and ApaI allowed detection of a total of 37 distinct genotypes, most of them comprised at least two isolates. Six appeared in more than one vintage, one of them being present in the three studied years. Moreover, four genotypes were indistinct of the strains isolated from the air of this same winery in 2007 vintage. The frequency of participation of each genotype varied from year to year, thus dominant genotypes at one year were minority or not present at another year. This suggests that distinct indigenous O. oeni strains are better adapted to the different winery conditions every year. Predominant genotypes that appeared in more than one vintage and lead to quality wines with low histamine contents could be considered as interesting for selecting of new malolactic starter cultures.

Abstract
In the warm climate country of Greece malolactic fermentation (MLF) has received limited attention. Molecular techniques and High Performance Liquid Chromatography (HPLC) were used to study the genetic polymorphism of autochthonous lactic acid bacteria developing towards the end of spontaneous MLF of Greek red wines and for the assessment of their potential to produce harmful biogenic amines. This research revealed that native Oenococcus oeni isolates are very much adapted to specific winery conditions since the majority of spontaneous MLF were driven mostly or exclusively by a single strain of O. oeni. Native O. oeni strains showed only limited dispersion since cluster analysis uncovered only few common genotypes among indigenous isolates from different wineries. The genotype of a frequently used malolactic starter was more than often detected among autochthonous isolates without nevertheless compromising the biodiversity of natural microflora residing in wineries but rather becoming a part of it. For the majority of the wine samples studied, MLF implementation and storage in bottles resulted in negligible changes on the levels of the BA histamine, tyramine, phenylethylamine, cadaverine as well as of ethylamine, methylamine, isobutylamine. We provide evidence that autochthonous O. oeni isolates can only contribute to putrescine accumulation in Greek wines but still the specific trait behaves as strain-specific with a limited dispersion.

Abstract
Among the lactic acid bacteria (LAB) present in the oenological microbial ecosystem, Oenococcus oeni, an acidophilic lactic acid bacterium, is essential during winemaking. It outclasses all other bacterial species during malolactic fermentation (MLF). Oenological performances, such as malic acid degradation rate and sensorial impact, vary significantly according to the strain. The genetic diversity of the O. oeni species was evaluated using a multilocus sequence typing (MLST) scheme. Seven housekeeping genes were sequenced for a collection of 258 strains that had been isolated all over the world (particularly Burgundy, Champagne, and Aquitaine, France, Chile, South Africa, and Italy) and in several wine types (red wines, white wines, and champagne) and cider. The allelic diversity was high, with an average of 20.7 alleles per locus, many of them being rare alleles. The collection comprised 127 sequence types, suggesting an important genotypic diversity. The neighbor-joining phylogenetic tree constructed from the concatenated sequence of the seven housekeeping genes showed two major phylogenetic groups, named A and B. One unique strain isolated from cider composed a third group, rooting the phylogenetic tree. However, all other strains isolated from cider were in group B. Eight phylogenetic subgroups were statistically differentiated and could be delineated by the analysis of only 32 mutations instead of the 600 mutations observed in the concatenated sequence of the seven housekeeping genes. Interestingly, in group A, several phylogenetic subgroups were composed mostly of strains coming from a precise geographic origin. Three subgroups were identified, composed of strains from Chile, South Africa, and eastern France.

Abstract
Control over malolactic fermentation (MLF) is a difficult goal in winemaking and needs rapid methods to monitor Oenococcus oeni malolactic starters (MLS) in a stressful environment such as wine. In this study, we describe a novel quantitative PCR (QPCR) assay enabling the detection of an O. oeni strain during MLF without culturing. O. oeni strain LB221 was used as a model to develop a strain-specific sequence-characterized amplified region (SCAR) marker derived from a discriminatory OPA20-based randomly amplified polymorphic DNA (RAPD) band. The 5' and 3' flanking regions and the copy number of the SCAR marker were characterized using inverse PCR and Southern blotting, respectively. Primer pairs targeting the SCAR sequence enabled strain-specific detection without cross amplification of other O. oeni strains or wine species of lactic acid bacteria (LAB), acetic acid bacteria (AAB), and yeasts. The SCAR-QPCR assay was linear over a range of cell concentrations (7 log units) and detected as few as 2.2 × 10(2) CFU per ml of red wine with good quantification effectiveness, as shown by the correlation of QPCR and plate counting results. Therefore, the cultivation-independent monitoring of a single O. oeni strain in wine based on a SCAR marker represents a rapid and effective strain-specific approach. This strategy can be adopted to develop easy and rapid detection techniques for monitoring the implantation of inoculated O. oeni MLS on the indigenous LAB population, reducing the risk of unsuccessful MLF.

Abstract
AIMS To characterize the genetic and phenotypic diversity of 135 lactic acid bacteria (LAB) strains isolated from Italian wines that undergone spontaneous malolactic fermentation (MLF) and propose a multiphasic selection of new Oenococcus oeni malolactic starters. METHODS AND RESULTS One hundred and thirty-five LAB strains were isolated from 12 different wines. On the basis of 16S amplified ribosomal DNA restriction analysis (ARDRA) with three restriction enzymes and 16S rRNA gene sequencing, 120 O. oeni strains were identified. M13-based RAPD analysis was employed to investigate the molecular diversity of O. oeni population. Technological properties of different O. oeni genotypes were evaluated in synthetic medium at increasing selective pressure, such as low pH (3.5, 3.2 and 3.0) and high ethanol values (10, 11 and 13% v/v). Finally, the malolactic activity of one selected strain was assessed in wine by malolactic trial in winery. CONCLUSIONS The research explores the genomic diversity of wine bacteria in Italian wines and characterizes their malolactic metabolism, providing an efficient strategy to select O. oeni strains with desirable malolactic performances and able to survive in conditions simulating the harsh wine environment. SIGNIFICANCE AND IMPACT OF THE STUDY This article contributes to a better understanding of microbial diversity of O. oeni population in Italian wines and reports a framework to select new potentially O. oeni starters from Italian wines during MLF.

Abstract
Oenococcus oeni is the acidophilic lactic acid bacterial species most frequently associated with malolactic fermentation of wine. Since the description of the species (formerly Leuconostoc oenos), characterization of indigenous strains and industrially produced cultures by diverse typing methods has led to divergent conclusions concerning the genetic diversity of strains. In the present study, a multilocus sequence typing (MLST) scheme based on the analysis of eight housekeeping genes was developed and tested on a collection of 43 strains of diverse origins. The eight targeted loci were successfully amplified and sequenced for all isolates. Only three to 11 different alleles were detected for these genes. The average nucleotide diversity also was rather limited (0.0011 to 0.0370). Despite this limited allelic diversity, the combination of alleles of each strain disclosed 34 different sequence types, which denoted a significant genotypic diversity. A phylogenetic analysis of the concatenated sequences showed that all strains form two well distinct groups of 28 and 15 strains. Interestingly, the same groups were defined by pulsed-field gel electrophoresis, although this method targets different genetic variations. A minimum spanning tree analysis disclosed very few and small clonal complexes. In agreement, statistical analyses of MLST data suggest that recombination events were important during O. oeni evolution and contributed to the wide dissemination of alleles among strains. Taken together, our results showed that MLST is more efficient than pulsed-field gel electrophoresis for typing O. oeni strains, and they provided a picture of the O. oeni population that explains some conflicting results previously obtained.
