Plasmid pIL7 (33 kilobases) from Streptococcus lactis enhances UV resistance and prophage stability. A 5.4-kilobase pIL7 fragment carrying genes coding for both characters was cloned into S. lactis, using plasmid pHV1301 as the cloning vector. The recombinant plasmid was subsequently transferred to three other S. lactis strains by transformation or protoplast fusion. Cloned genes were expressed...
Lactococcus lactis subsp. lactis NCDO 2118 is a nondairy lactic acid bacterium, a xylose fermenter, and a gamma-aminobutyric acid (GABA) producer isolated from frozen peas. Here, we report the complete genome sequence of L. lactis NCDO 2118, a strain with probiotic potential activity.
Lactococcus lactis plant isolates identifies adaptation mechanisms to the plant niche Running title: Genotype-phenotype matching of L. lactis plant isolates ABSTRACT Lactococcus lactis is a primary constituent of many starter cultures used for the manufacturing of fermented dairy products, but the species also occurs in various non-dairy niches such as (fermented) plant material. Three genome s...
Lactococcus lactis is a lactic acid bacterium used in the production of many fermented foods, such as dairy products. Here, we report the genome sequence of L. lactis subsp. lactis TOMSC161, isolated from nonscalded curd pressed cheese. This genome sequence provides information in relation to dairy environment adaptation.
A Lactococcus lactis glycine-betaine transport system was identified by functional complementation of an Escherichia coli proP proU mutant with a gene library from L. lactis sbsp. cremoris. The cloned locus forms an operon highly homologous to opuA, encoding a glycine-betaine uptake system of Bacillus subtilis. Disruption of opuA in L. lactis abolished protection by glycine-betaine against elev...
Staphylococcus aureus encodes two HtrA-like serine surface proteases, called HtrA1 and HtrA2. The roles of these HtrA homologs were distinguished by expression studies in a heterologous host, Lactococcus lactis, whose single extracellular protease, HtrA(Ll), was absent. HtrA(Ll) is involved in stress resistance, and processing and/or degradation of extracellular proteins. Controlled expression ...
BACKGROUND Leishmania is a mammalian parasite affecting over 12 million individuals worldwide. Current treatments are expensive, cause severe side effects, and emerging drug resistance has been reported. Vaccination is the most cost-effective means to control infectious disease but currently there is no vaccine available against Leishmaniasis. Lactococcus lactis is a non-pathogenic, non-coloniz...
Using Streptococcus thermophilus phages, plasmid transduction in Lactococcus lactis was demonstrated. The transduction frequencies were 4 orders of magnitude lower in L. lactis than in S. thermophilus. These results are the first evidence that there is phage-mediated direct transfer of DNA from S. thermophilus to L. lactis. The implications of these results for phage evolution are discussed.
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.
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.
