Abstract
An undescribed wet rot of roots was observed in surveys of recently harvested sugar beet roots in Idaho and eastern Oregon in 2004 and 2005. Microorganisms isolated from 287 roots fell into the following groups: A (41% of strains), B (29%), C (17%), D (11%), E (2%), and F (1%). Groups A, B, C, and F were composed of bacteria while groups D and E were yeasts. Subgroup A1 (80% of group A strains) included Leuconostoc mesenteroides subsp. dextranicum strains and subgroup A2 (20%) contained Lactobacillus strains. Group B was dominated by subgroup B1 (92% of strains), which included Gluconobacter strains. When only one organism was isolated from rotted roots, strains from subgroup A1 were isolated most frequently. Group C was composed of enteric bacteria. Strain B322 of L. mesenteroides subsp. dextranicum caused the most severe rot on root slices and produced symptoms similar to those in harvested roots. Results suggest that L. mesenteroides subsp. dextranicum is among the first bacterial species to enter sugar beet roots, closely following fungal infections or entering directly through openings such as growth cracks. The bacterial rot leads to yield loss in the field but likely also leads to storage and factory-processing problems.

Abstract
The anaerobic fermentation of glucose by Leuconostoc mesenteroides via the reductive pentose phosphate pathway leads to the accumulation of lactic acid and ethanol. The isotope redistribution coefficients (a(ij)) that characterize the specific derivation of each hydrogen atom in ethanol in relation to the non-exchangeable hydrogen atoms in glucose and the medium water have been determined using quantitative (2)H NMR. First, it is confirmed that the hydrogens of the methylene group are related only to the 1 and 3 positions of glucose via the NAD(P)H pool and not to the 4 position, in contrast to ethanol produced by Saccharomyces cerevisiae. Second, it is found that the conversion factors (C(f)) for the transfer of hydrogen to the pro-S and pro-R positions of the methylene group are not equivalent: the C(f)-1-R:C(f)-1-S ratio is 2.1, whereas the C(f)-3-R:C(f)-3-S ratio is 0.8. It is shown that this non-equivalence is not determined by the stereochemistry of the terminal NADH- and NADPH-dependent alcohol dehydrogenases, but is dependent on the cofactor selectivities of the reductive and oxidative steps of the reduced nucleotide cycle.

Abstract
A plasmid-borne diacetyl (acetoin) reductase (butA) from Leuconostoc pseudomesenteroides CHCC2114 was sequenced and cloned. Nucleotide sequence analysis revealed an open reading frame encoding a protein of 257 amino acids which had high identity at the amino acid level to diacetyl (acetoin) reductases reported previously. Downstream of the butA gene of L. pseudomesenteroides, but coding in the opposite orientation, a putative DNA recombinase was identified. A two-step PCR approach was used to construct FPR02, a butA mutant of the wild-type strain, CHCC2114. FPR02 had significantly reduced diacetyl (acetoin) reductase activity with NADH as coenzyme, but not with NADPH as coenzyme, suggesting the presence of another diacetyl (acetoin)-reducing activity in L. pseudomesenteroides. Plasmid-curing experiments demonstrated that the butA gene is carried on a 20-kb plasmid in L. pseudomesenteroides.

Abstract
AIMS To identify and characterize an oligopeptide transport system in Leuconostoc mesenteroides CNRZ 1473. METHODS AND RESULTS The uptake of a model substrate was monitored by determining intracellular concentrations of the corresponding amino acids by means of reversed-phase HPLC analysis. The oligopeptide transport system is specific for peptides containing at least four amino acid residues and operative under physiological conditions of growth. It is expressed maximally in the presence of oligopeptides, enhanced in the presence of Mg2+ or Ca2+ ions, and driven by ATP or a related energy-rich phosphorylated intermediate. CONCLUSIONS The study showed evidence for and characterized the oligopeptide transport system of Leuc. mesenteroides for the first time. SIGNIFICANCE AND IMPACT OF THE STUDY The potential of the findings is discussed with reference to the growth of Leuc. mesenteroides in mixed-strain cultures for the dairy industry.

Abstract
Oenococcus oeni (formerly Leuconostoc oenos) can perform malolactic fermentation, converting L-malate to L-lactate and carbon dioxide, in wines. The energy and redox potential required to support the growth of the micro-organism are supplied mainly by the consumption of carbohydrates via the heterolactic pathway. In the first steps of hexose metabolism two molecules of NAD(P)(+) are consumed, which must be regenerated in later reactions. The aim of this work was to test if aerobic growth of O. oeni promotes higher cell yields than anaerobic conditions, as has been shown for other lactic acid bacteria. O. oeni M42 was found to grow poorly under aerobic conditions with glucose as the only carbohydrate in the medium. It was demonstrated that O(2) inactivates the enzymes of the ethanol-forming pathway, one of the two pathways which reoxidizes NAD(P)(+) cofactors in the heterolactic catabolism of glucose. These results suggest that the regeneration of cofactors is the limiting factor for the aerobic consumption of glucose. When external electron acceptors, such as fructose or pyruvate, were added to glucose-containing culture medium the growth of O. oeni was stimulated slightly; fructose was converted to mannitol, oxidizing two molecules of NAD(P)H, and pyruvate was transformed to lactate, enabling the regeneration of NAD(+). The addition of cysteine seemed to suppress the inactivation of the ethanol-forming pathway enzymes by O(2), enabling glucose consumption in aerobic conditions to reach similar rates to those found in anaerobic conditions.

Abstract
An evaluation of various lactic acid bacteria (LAB) for the fermentation of cabbage, carrot and beet-based vegetable products was carried out. As part of a screening process, the growth of 15 cultures in a vegetable juice medium (VJM) was characterized by automated spectrophotometry. Acidification patterns as well as viability during storage of the LAB were also established. There were greater differences between the pure cultures than the mixed ones with respect to growth in VJM and viability during storage. Reductions in viable cell counts during storage of the fermented VJM occurred more rapidly with a Leuconostoc strain than for pediococci or lactobacilli. Inoculation of vegetables was carried out with cultures of Lactobacillus plantarum NK-312, Pediococcus acidilactici AFERM 772 and Leuconostoc mesenteroides BLAC which were rehydrated in a brine. This rehydration procedure was not detrimental to viability. During fermentation of a carrot/cabbage vegetable mix, sugar metabolism was characterized by the assimilation of both glucose and fructose, but sugars remained in the fermented vegetables when acidification stopped. The pH in the LAB-inoculated vegetables after 72 h at 20 degrees C was significantly lower (by 0.2 units) than the uninoculated control. Inoculation with LAB designed for silage fermentation resulted in the inhibition of acetic acid production, and reduced the production of ethanol during fermentation. The selection process on VJM enabled the preparation of a mixed culture that was more rapid than the silage inoculants in acidifying the medium and was more effective in reducing the production of gas during the fermentation and storage of the fermented vegetables.

Abstract
A gene encoding a protein homologous to known bacterial N-acetyl-muramidases has been cloned from Leuconostoc citreum by a PCR-based approach. The encoded protein, Mur, consists of 209 amino acid residues with a calculated molecular mass of 23,821 Da including a 31-amino-acid putative signal peptide. In contrast to most of the other known peptidoglycan hydrolases, L. citreum Mur protein does not contain amino acid repeats involved in cell wall binding. The purified L. citreum Mur protein was shown to exhibit peptidoglycan-hydrolyzing activity by renaturing sodium dodecyl sulfate-polyacrylamide gel electrophoresis. An active chimeric protein was constructed by fusion of L. citreum Mur to the C-terminal repeat-containing domain (cA) of AcmA, the major autolysin of Lactococcus lactis. Expression of the Mur-cA fusion protein was able to complement an acmA mutation in L. lactis; normal cell separation after cell division was restored by Mur-cA expression.

Abstract
For a long time, the identification of the Leuconostoc species has been limited by a lack of accurate biochemical and physiological tests. Here, we use a combination of RAPD, 16S rDNA sequencing, and 16S rDNA fragment amplification with specific primers to classify different leuconostocs at the species and strain level. We analysed the molecular diversity of a collection of 221 strains mainly isolated from traditional French cheeses. The majority of the strains were classified as Leuconostoc mesenteroides (83.7%) or Leuconostoc citreum (14%) using molecular techniques. Despite their presence in French cheeses, the role of L. citreum in traditional technologies has not been determined, probably because of the lack of strain identification criteria. Only one strain of Leuconostoc lactis and Leuconostoc fallax were identified in this collection, and no Weissella paramesenteroides strain was found. However, dextran negative variants of L. mesenteroides, phenotypically misclassified as W. paramesenteroides, were present. The molecular techniques used did not allow us to separate strains of the three L. mesenteroides subspecies (mesenteroides, dextranicum and cremoris). In accordance with previously published results, our findings suggest that these subspecies may be classified as biovars. Correlation found between phenotypes dextranicum and mesenteroides of L. mesenteroides and cheese technology characteristics suggests that certain strains may be better adapted to particular technological environments.

Abstract
The biodiversity of growth and energetics in Leuconostoc sp. has been studied in MRS lactose medium with and without citrate. On lactose alone, Ln. lactis has a growth rate double that of Ln. cremoris and Ln. mesenteroides. The pH is a more critical parameter for Ln. mesenteroides than for Ln. lactis or Ln. cremoris; without pH control Ln. mesenteroides is unable to acidify the medium under pH 4.5, while with pH control and as a consequence of a high Y(ATP) its growth is greater than Ln. lactis and Ln. cremoris. In general, lactose-citrate co-metabolism increases the growth rate, the biomass synthesis, the lactose utilisation ratio, and the production of lactate and acetate from lactose catabolism. The combined effect of the pH and the co-metabolism lactose-citrate on the two components of the proton motive force (deltap = deltapsi - ZdeltapH) has been studied using resting-cell experiments. At neutral pH deltap is nearly entirely due to the deltapsi, whereas at acidic pH the deltapH is the major component. On lactose alone, strains have a different aptitude to regulate their intracellular pH value, for Ln. mesenteroides it drastically decreases at acidic pH values (pH, = 5.2 for pH 4), while for Ln. lactis and Ln. cremoris it remains above pH 6. Lactose-citrate co-metabolism allows a better control of pH homeostasis in Ln. mesenteroides, consequently the pHi becomes homogeneous between the three strains studied, for pH 4 it is in an interval of 0.3 pH unit (from pHi = 6.4 to pHi = 6.7). In this metabolic state, and as a consequence of the variation in deltapH, and to some extent in the deltapsi, the difference of deltap between the three strains is restricted to an interval of 20 mV.

Abstract
Of 215 leuconostocs isolated from field grass, natural whey cultures and water-buffalo milk, 178 were identified as Leuconostoc mesenteroides ssp. mesenteroides while 37 strains could not be identified. Biochemical characterization allowed seven groups to be defined. Representative strains of each group and different habitat and nine reference strains were selected for further analyses. Protein profiles appeared suitable for species discrimination, but did not differentiate between the three subspecies of Leuc. mesenteroides. The technique also showed some differences among equivocal strains. DNA fingerprinting for most strains of Leuc. mesenteroides ssp. mesenteroides examined showed a different restriction pattern from that of the type strain. Ribotyping was not useful for discriminating species and subspecies of the genus Leuconostoc: Leuc. mesenteroides ssp. mesenteroides and ssp. dextranicum showed the same ribopattern as Leuc. lactis while Leuc. mesenteroides ssp. cremoris exhibited a pattern distinct from all the other species examined. On the basis of ARDRA-PCR, two main groups could be distinguished: the larger group included Leuc. mesenteroides, Leuc. lactis, Leuc. pseudomesenteroides and some unidentifiable strains; the second one included Leuc. citreum, Leuc. fallax, Weissella paramesenteroides and some unidentified strains.

Abstract
A chemically defined medium for the growth of Leuconostoc mesenteroides was developed. This medium contained lactose, Mn(sup2+), Mg(sup2+), 12 amino acids, eight vitamins, adenine, uracil, and Tween 80. We showed the beneficial effect of aerobic conditions on growth and that potassium phosphate (135 mM) is a suitable buffer. The growth rate in this medium was 0.85 (plusmn) 0.10 h(sup-1) for the six strains examined, and cell densities up to 3.5 x 10(sup9) CFU/ml were attained.
