A selective medium (LUSM medium) for the isolation of Leuconostoc spp. was developed. This medium contained 1.0% glucose, 1.0% Bacto Peptone (Difco), 0.5% yeast extract (BBL), 0.5% meat extract (Difco), 0.25% gelatin (Difco), 0.5% calcium lactate, 0.05% sorbic acid, 75 ppm of sodium azide (Sigma), 0.25% sodium acetate, 0.1% (vol/vol) Tween 80, 15% tomato juice, 30 micrograms of vancomycin (Sigm...

Bacteria in the genus Leuconostoc are very infrequent opportunistic pathogens. We report a case of meningitis due to Leuconostoc mesenteroides sub sp. mesenteroides associated with central nervous system tuberculosis in a patient with advanced HIV/AIDS infection.

In spite of a global concern on the transfer of antibiotic resistances (AR) via the food chain, limited information exists on this issue in species of Leuconostoc and Weissella, adjunct cultures used as aroma producers in fermented foods. In this work, the minimum inhibitory concentration was determined for 16 antibiotics in 34 strains of dairy origin, belonging to Leuconostoc mesenteroides (18...

Leuconostoc mesenteroides subsp. mesenteroides is one of the most predominant lactic acid bacterial groups during kimchi fermentation. Here, we report the complete genome sequence of L. mesenteroides subsp. mesenteroides J18, which was isolated from kimchi. The genome of the strain consists of a 1,896,561-bp chromosome and five plasmids.

A cryptic plasmid, pMBLR00, from Leuconostoc mesenteroides subsp. mesenteroides KCTC 3733 was isolated, characterized, and used for the construction of a cloning vector to engineer Leuconostoc species. pMBLR00 is a rolling circle replication plasmid, containing 3,370 base pairs. Sequence analysis revealed that pMBLR00 has 3 open reading frames: Cop (copy number control protein), Rep (replicatio...

A strain of Leuconostoc gelidum, designated strain JB7, was isolated from kimchi, the representative Korean traditional fermented food. Here we announce the complete genome sequence of L. gelidum strain JB7, consisting of a 1,893,499-bp circular chromosome with a G+C content of 36.68%, and provide a description of its annotation.

Leuconostoc is the main group of heterofermentative bacteria found in mesophilic dairy starters. They grow in close symbiosis with the Lactococcus population and are able to degrade citrate. Here we present a draft genome sequence of Leuconostoc mesenteroides subsp. cremoris strain T26.

Here, we report the complete genome sequence of strain LK-151 of Leuconostoc mesenteroides, which was isolated from a Japanese sake cellar and has the potential to produce large amounts of d-amino acids, namely, d-Ala and d-Glu. The genome contains 4 genes related to d-amino acid production.

O'Barr, Thomas P. (Agricultural Research Service, Washington, D.C.). Effect of alanine and threonine on the synthesis of serine by Leuconostoc mesenteroides. J. Bacteriol. 86:1321-1325. 1963.-Growth of Leuconostoc mesenteroides in the absence of serine was inhibited by l-alanine and l-threonine. Varying the glycine concentration when l-alanine was present suggested a direct relationship between...

Leuconostoc species are gaining importance as pathogenic organisms. We present the first case of odontogenic infection caused by Leuconostoc spp. Isolates initially identified as streptococci were found to be vancomycin resistant. Rigorous bacteriologic investigation subsequently classified these organisms as Leuconostoc mesenteroides.
