The Lactococcus lactis Pan-Plasmidome [PDF]
Frontiers in Microbiology, 2019 Plasmids are autonomous, self-replicating, extrachromosomal genetic elements that are typically not essential for growth of their host. They may encode metabolic capabilities, which promote the maintenance of these genetic elements, and may allow adaption to specific ecological niches and consequently enhance survival.

Replacement recombination in Lactococcus lactis [PDF]
Journal of Bacteriology, 1991 In the pUC18-derived integration plasmid pML336 there is a 5.3-kb chromosomal DNA fragment that carries the X-prolyl dipeptidyl aminopeptidase gene (pepXP). The gene was inactivated by the insertion of an erythromycin resistance determinant into its coding sequence.

Gene expression in Lactococcus lactis [PDF]
FEMS Microbiology Letters, 1992 Lactic acid bacteria are of major economic importance, as they occupy a key position in the manufacture of fermented foods. A considerable body of research is currently being devoted to the development of lactic acid bacterial strains with improved characteristics, that may be used to make fermentations pass of more efficiently, or to make new ...

Functionality of Sortase A in Lactococcus lactis [PDF]
Applied and Environmental Microbiology, 2010 ABSTRACT Lactococcus lactis IL1403 harbors a putative sortase A (SrtA) and 11 putative sortase substrates that carry the canonical LPXTG signature of such substrates. We report here on the functionality of SrtA to anchor five LPXTG substrates to the cell wall, thus suggesting that SrtA is the housekeeping sortase in

Nature Communications, 2022 The probiotic Lactococcus lactis has been used for the delivery of therapeutic molecules. Here the authors engineer Lactococcus lactis to express a fusion protein of Flt3L and OX40 ligand, eliciting anti-tumor immune response in preclinical cancer models.

Tryptophan biosynthesis genes in Lactococcus lactis subsp. lactis [PDF]
Journal of Bacteriology, 1992 The Lactococcus lactis chromosomal region containing the seven structural genes required for tryptophan biosynthesis was characterized by cloning and sequencing. All of the trp genes were identified by the homology of their products with known Trp proteins from other organisms.

Bactéries lactiques du lait de chamelle d'Algérie: mise en évidence de souches de Lactococcus résistantes au sel [PDF]
Tropicultura, 2006 Lactic Acid Bacteria of Camel Milk: Presence of Salt Resistant Strains of Lactococcus. Different lactic acid bacteria were isolated from raw camel milk; respectively Lactococcus, Leuconostoc and Lactobacillus strains.

Isolation and characterization of Lactococcus lactis subsp. lactis promoters [PDF]
Applied and Environmental Microbiology, 1991 DNA fragments with promoter activity were isolated from the chromosome of Lactococcus lactis subsp. lactis. For the isolation, a promoter probe vector based on the cat gene was constructed, which allowed direct selection with chloramphenicol in Bacillus subtilis and L. lactis.

Divergence of Genomic Sequences between Lactococcus lactis subsp. lactis and Lactococcus lactis subsp. cremoris [PDF]
Applied and Environmental Microbiology, 1992 Relatedness between Lactococcus lactis subsp. cremoris and L. lactis subsp. lactis was assessed by Southern hybridization analysis, with cloned chromosomal genes as probes.

Revista do Instituto de Latícinios Cândido Tostes, 2019 Sheep milk has different physicochemical properties, which means that its derived products have a high added value. Part of these properties is conferred by lactic bacteria which play important activities in the raw milk.
