Leuconostoc mesenteroides P45 was isolated from the traditional Mexican pulque beverage. We report its draft genome sequence, assembled in 6 contigs consisting of 1,874,188 bp and no plasmids. Genome annotation predicted a total of 1,800 genes, 1,687 coding sequences, 52 pseudogenes, 9 rRNAs, 51 tRNAs, 1 noncoding RNA, and 44 frameshifted genes.

Viscous broths were produced by growing Leuconostoc mesenteroides on a medium containing whey supplemented with sucrose. When combined with similarly produced xanthan-containing broths, a synergistic increase in viscosity was observed.

We used combinatorial engineering to investigate the relationships between structure and linkage specificity of the dextransucrase DSR-S from Leuconostoc mesenteroides NRRL B-512F, and to generate variants with altered specificity. Sequence and structural analysis of glycoside-hydrolase family 70 enzymes led to eight amino acids (D306, F353, N404, W440, D460, H463, T464 and S512) being targeted...

A study of the influence of different plant terpenoids and amino sugar derivate acarbose on the activity of glycosyltransferase complex and purified dextransucrase from Leuconostoc mesenteroides URE 13 strain was carried out. All the tested terpenoids showed an inhibitory effect on glycosyltransferases from strain URE 13 at concentration 0.34 mmol. Out of all studied diterpenoids splendidin sho...

This paper presents the first report of bacteriophage isolated from commercial vegetable fermentations. Nine phages were isolated from two 90-ton commercial sauerkraut fermentations. These phages were active against fermentation isolates and selected Leuconostoc mesenteroides and Lactobacillus plantarum strains, including a starter culture. Phages were characterized as members of the Siphovirid...

Leuconostoc mesenteroides406 was isolated from the traditional fermented mare milk airag in Tuv Aimag, Mongolia. This strain produces an antilisterial bacteriocin. Here, we report the draft genome sequence of this organism.

Minimum inhibitory concentrations (MICs) of daptomycin, linezolid, and vancomycin against 212 isolates of Listeria monocytogenes, Pediococcus, Leuconostoc, Rhodococcus and Nocardia species were determined by the broth microdilution method and the Etest (daptomycin only). Except for Leuconostoc species, daptomycin Etest MICs showed >90% agreement with MICs by the broth microdilution method.

A rare case of purulent meningitis caused by vancomycin-resistant Leuconostoc sp. is reported. The patient was treated successfully with penicillin G, and there were no neurological sequelae. We recommend that all gram-positive cocci isolated from cerebrospinal fluid and blood be fully identified so as not to confuse Leuconostoc spp. with more commonly isolated pathogens such as pneumococci and...

Leuconostoc gelidum KCTC 3527 is found mainly in vegetables and plays an important role in vegetable fermentation, including that of Korean traditional kimchi. Here we announce the draft genome sequence of Leuconostoc gelidum KCTC 3527, isolated from Korean traditional kimchi, and describe major findings from its annotation.

Article info: Received: 22 February 2012 In revised form: 28 April 2012 Accepted: 30 April 2012 ABSTRACT Dextransucrases are enzymes that transfer the glucosyl moiety from sucrose to other acceptor molecules. In the present study, we have investigated the biosynthesis of dextransucrases by two strains of Leuconostoc mesenteroides isolated from Bulgarian fermented products. Extracellular dextran...
