TranscriptomicsComparative genome hybridization profiles of six strains of Lactococcus lactis
The intra sub-species diversity of six strains of Lactococcus lactis subsp. lactis was investigated at the genomic level and in terms of phenotypic and transcriptomic profiles in UF-cheese model. Six strains were isolated from various sources, but all are exhibiting a dairy phenotype. Our results sh...

TranscriptomicsResponse of Lactococcus lactis to isoleucine starvation
For the first time in Lactococcus lactis, amino acid starvation response was characterized. The natural imposition of isoleucine starvation, by its consumption during growth, associated to transcript profiling, allowed defining exhaustively this stress stimulon. It consisted of a general induction o...

TranscriptomicsLactococcus lactis stringent response
The stringent response was defined in Lactococcus lactis through transcript profiling after the addition of a chemical inductor, the norvaline. Gene expression was measured in the exponential growth phase (reference sample) and at 1.6 h after norvaline addition. Four hundred and sixty one differenti...

TranscriptomicsLactococcus lactis response to isoleucine starvation
Amino acid assimilation and metabolism are crucial for bacterial growth and survival and this is particularly obvious for lactic acid bacteria (LAB) that are generally auxotroph for various amino acids. However, amino acid assimilation is poorly characterized and a complete description of the respon...

TranscriptomicspBL1 impairs cellobiose metabolism in Lactococcus lactis
pBL1 is a Lactococcus lactis theta-replicating 10.9-kbp plasmid that encodes the synthetic machinery of the bacteriocin Lcn972. In this work, the transcriptomes of exponentially growing L. lactis with and without pBL1 were compared. A discrete response was observed with a total of ten genes showing ...

TranscriptomicsResponse of Lactococcus lactis to different growth rates
The development of transcriptomic tools has allowed exhaustive description of stress responses. These responses always superimpose a general response associated to growth rate decrease and a specific one corresponding to the stress. The exclusive growth rate response can be achieved through chemosta...

MetabolomicsMetabolic cooperation and spatiotemporal niche partitioning in a kefir microbial community; Interaction between the kefir isolates Lactococcus lactis and Acetobacter fabarum (GC-MS)

Microbial communities often undergo intricate compositional changes yet also maintain stable coexistence of diverse species. The mechanisms underlying long-term coexistence remain unclear, as system-wide studies have been largely limited to engineered communities, ex situ adapted cultures, or syn...

TranscriptomicsGenome Sequences of Lactococcus lactis MG1363 (Revised) and NZ9000 and Comparative Physiological Studies
Lactococcus lactis NZ9000 and its parent MG1363 are the most commonly used lactic acid bacteria for expression and physiological studies. We noted unexpected but significant differences in the growth behaviors of both strains. We sequenced the entire genomes of the original NZ9000 and MG1363 strains...
