Complete Genome Sequence of Lactococcus Lactis subsp. cremoris A76
Journal of Bacteriology, 2012Co-Authors: Alexander Bolotin, Benoît Quinquis, S D Ehrlich, Alexander SorokinAbstract:We report the complete genome sequence of Lactococcus Lactis subsp. cremoris A76, a dairy strain isolated from a cheese production outfit. Genome analysis detected two contiguous islands fitting to the L. Lactis subsp. Lactis rather than to the L. Lactis subsp. cremoris lineage. This indicates the existence of genetic exchange between the diverse subspecies, presumably related to the technological process.

Divergence of Genomic Sequences between Lactococcus Lactis subsp. Lactis and Lactococcus Lactis subsp. cremoris.
Applied and environmental microbiology, 1992Co-Authors: Jean-jacques Godon, S. Dusko Ehrlich, Christine Delorme, Pierre RenaultAbstract:Abstract Relatedness between Lactococcus Lactis subsp. cremoris and L. Lactis subsp. Lactis was assessed by Southern hybridization analysis, with cloned chromosomal genes as probes. The results indicate that strains of the two subspecies form two distinct groups and that the DNA sequence divergence between L. Lactis subsp. Lactis and L. Lactis subsp. cremoris is estimated to be between 20 and 30%. The previously used phenotypic criteria do not fully discriminate between the groups; therefore, we propose a new classification which is based on DNA homology. In agreement with this revised classification, the L. Lactis subsp. Lactis and L. Lactis subsp. cremoris strains from our collection have distinct phage sensitivities.

A type IC restriction-modification system in Lactococcus Lactis.
Journal of bacteriology, 1998Co-Authors: Catherine Schouler, Florence Clier, Alda Luisa Lerayer, S. Dusko Ehrlich, Marie-christine ChopinAbstract:Three genes coding for the endonuclease, methylase, and specificity subunits of a type I restriction-modification (R-M) system in the Lactococcus Lactis plasmid pIL2614 have been characterized. Plasmid location, sequence homologies, and inactivation studies indicated that this R-M system is most probably of type IC.

Application of RAPD analysis for identification of Lactococcus Lactis subsp. cremoris strains isolated from artisanal cultures.
Microbiological research, 2002Co-Authors: D. Samarzija, Neven Antunac, S. Sikora, S. Redzepovic, J. L. HavranekAbstract:Randomly amplified polymorphic DNA (RAPD) was used for identification of Lactococcus Lactis subsp. cremoris strains isolated 40 years ago from various dairy homemade products. Total genomic DNAs from six randomly chosen isolates and the reference strain Lactococcus Lactis subsp. cremoris NIZO B64 were amplified using four different 10-mer primers. Although most RAPD fragments were common to all six isolates, a sufficient number of polymorphic fragments were also detected that allowed clear distinction of the isolates and the reference strain. The results indicate that RAPD analysis could be a useful and efficient method to distinguish Lactococcus Lactis subsp. cremoris at the strain level and to detect genetic diversity.
