Two Leuconostoc mesenteroides strains NCDC 744 and NCDC 745 were evaluated for exopolysaccharides (EPS) production in whey and MRS medium. Paneer whey medium supplemented with 10% sucrose, 0.1 % yeast extract and 0.1 % K2HPO4 was found to be proferred medium for EPS production. Among two strains L. mesenteroides NCDC 744 produced significantly higher EPS (12.7 ± 0.24 gm/L) as compared to NCDC 7...

A total of 84 of 150 vancomycin-resistant (defined as no inhibition of bacterial growth around a 30-micrograms vancomycin disk placed on 5% sheep blood-Trypticase soy agar [BBL Microbiology Systems, Cockeysville, Md.]) bacteria were definitively identified by determining the phenotypic criteria. The identity of representatives was also confirmed by DNA-DNA hybridizations. The following strains ...

The nonstarter lactic acid bacterium Leuconostoc pseudomesenteroides is a species widely found in the dairy industry and plays a key role in the formation of aromatic compounds. Here, we report the first genome sequence of a dairy strain of Leuconostoc pseudomesenteroides, which is 2 Mb.

Leuconostoc inhae strain KCTC 3774 is a Gram-positive, non-spore-forming, heterofermentative, spherical or lenticular lactic acid bacterium. Here we announce the draft genome sequence of Leuconostoc inhae KCTC 3774, isolated from traditional Korean kimchi, and describe major findings from its annotation.

MICs of daptomycin, linezolid, and vancomycin against 212 isolates, including Listeria monocytogenes and Pediococcus, Leuconostoc, Rhodococcus, and Nocardia spp., were determined by the broth microdilution method; daptomycin MICs were also determined by the Etest. Except with those for Leuconostoc spp., daptomycin Etest MICs showed >90% agreement with MICs obtained by the broth microdilution me...

Dairy siphovirus φLmd1, which infects starter culture isolate Leuconostoc mesenteroides subsp. dextranicum A1, showed resistance to pasteurization and was able to grow on 3 of the 4 commercial starter cultures tested. Its 26,201-bp genome was similar to that of Leuconostoc phage of vegetable origin but not to those of dairy phages infecting Lactococcus.

The citrate permease determinant (citP) in several Leuconostoc strains was demonstrated to be plasmid encoded by curing experiments and hybridization studies with a DNA fragment containing the citP gene from Lactococcus lactis subsp. lactis biovar diacetylactis NCDO176. Cloning and nucleotide sequence analysis of Leuconostoc lactis NZ6070 citP revealed almost complete identity to lactococcal citP.

In previous reports from this laboratory, a method for the assay of Dand L-methionine in biologic fluids with Leuconostoc mesenteroides P-60 and Lactobacillus fermenti 36 has been described (1, 2). The present communication describes a method for the determination of cysteine plus cystine in plasma. In a report by other workers, using the medium of Dunn et al. (3), the organisms Lactobacillus b...
