Draft Genome Sequences of 11 Lactococcus lactis subsp. cremoris Strains
The lactic acid bacterium Lactococcus lactis is widely used for the fermentation of dairy products. Here, we present the draft genome sequences of 11 L. lactis subsp. cremoris strains isolated from different environments.
متن کاملComplete genome sequence of Lactococcus lactis subsp. cremoris A76.
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 technologi...
متن کاملDifferentiation of Lactococcus lactis subspecies lactis and subspecies cremoris strains by their adaptive response to stresses.
Lactococcus lactis subspecies lactis (L. lactis ssp. lactis) and Lactococcus lactis subspecies cremoris (L. lactis ssp. cremoris) were investigated in respect to their response to acid, bile-salt and freezing stresses. First, the sublethal and lethal levels of each stress were determined for both subspecies. For acid stress, the levels were pH 4.5 and 2.5, respectively, for L. lactis ssp. lacti...
متن کاملLactococcus 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 کاملMechanism of Proteinase Release from Lactococcus lactis subsp. cremoris Wg2.
The procedure generally used for the isolation of extracellular, cell-associated proteinases of Lactococcus lactis species is based on the release of the proteinases by repeated incubation and washing of the cells in a Ca-free buffer. For L. lactis subsp. cremoris Wg2, as many as five incubations for 30 min at 29 degrees C are needed in order to liberate 95% of the proteinase. Proteinase releas...
