Lactococcus lactis ssp. lactis as Potential Functional Starter Culture.
The aim of this study is to identify and characterise potential autochthonous functional starter cultures in homemade horsemeat sausage. The dominant microflora in the samples of horsemeat sausage were lactic acid bacteria (LAB), followed by micrococci. Among the LAB, Lactococcus lactis ssp. lactis and Lactobacillus plantarum were the dominant species, and since the first is not common in ferme...
متن کاملInvestigation of the adaptation of Lactococcus lactis to isoleucine starvation integrating dynamic transcriptome and proteome information
BACKGROUND Amino acid assimilation is crucial for bacteria and this is particularly true for Lactic Acid Bacteria (LAB) that are generally auxotroph for amino acids. The global response of the LAB model Lactococcus lactis ssp. lactis was characterized during progressive isoleucine starvation in batch culture using a chemically defined medium in which isoleucine concentration was fixed so as to ...
متن کاملTranscriptome analysis of the Lactococcus lactis ArgR and AhrC regulons.
In previous studies, we have shown that direct protein-protein interaction between the two regulators ArgR and AhrC in Lactococcus lactis is required for arginine-dependent repression of the biosynthetic argC promoter and the activation of the catabolic arcA promoter. Here, we establish the global ArgR and AhrC regulons by transcriptome analyses and show that both regulators are dedicated to th...
متن کاملComplete Genome Sequence of Lactococcus lactis subsp. lactis KLDS4.0325
OBJECTIVE Aim to study the physiology and functionally important genes of Lactobacillus lactis KLDS4. 0325. METHODS We sequenced the complete genome of L. lactis KLDS4. 0325, drew the genomic map, and performed functional annotation and analysis in metabolism and probiotic. RESULTS L. lactis KLDS4. 0325 contains a chromosome of 2589261 bp, GC content is 35.4%, with 2662 predicted ORFs, of w...
متن کاملGenome Sequence of Lactococcus lactis subsp. lactis bv. diacetylactis LD61
Lactococcus lactis is widely used in the dairy industry. We report the draft genome sequence of L. lactis subsp. lactis bv. diacetylactis LD61, an industrial and extensively studied strain. In contrast to the closely related and plasmidless strain IL1403, LD61 contains 6 plasmids, and the genome sequence provides additional information related to adaptation to the dairy environment.
