Applicability of Lactococcus hircilactis and Lactococcus laudensis as dairy cultures

International Journal of Food Microbiology, 2018
The aim of this study was to evaluate whether Lactococcus hircilactis and Lactococcus laudensis can be used as starter cultures. To this end, the two lactococci were characterized for traits of technological and functional interest. Tests in milk included growth at 20, 25, 30, and 37 °C, flavor production, antioxidant (AO) activity, folate and ...

Lactococcus lactis and stress

Antonie van Leeuwenhoek, 1996
It is now generally recognized that cell growth conditions in nature are often suboptimal compared to controlled conditions provided in the laboratory. Natural stresses like starvation and acidity are generated by cell growth itself. Other stresses like temperature or osmotic shock, or oxygen, are imposed by the environment.

Lysozyme expression in Lactococcus lactis

Applied Microbiology and Biotechnology, 1992
Three lysozyme-encoding genes, one of eukaryotic and two of prokaryotic origin, were expressed in Lactococcus lactis subsp. lactis. Hen egg white lysozyme (HEL) could be detected in L. lactis lysates by Western blotting. No lysozyme activity was observed, however, presumably because of the absence of correctly formed disulphide bonds in the L.

Genome plasticity in Lactococcus lactis

Antonie van Leeuwenhoek, 2002
Comparative genome analyses contribute significantly to our understanding of bacterial evolution and indicate that bacterial genomes are constantly evolving structures. The gene content and organisation of chromosomes of lactic acid bacteria probably result from a strong evolutionary pressure toward optimal growth of these microorganisms in milk.

Endocarditis Caused by Lactococcus cremoris

Scandinavian Journal of Infectious Diseases, 2002
We describe a case of subacute endocarditis due to Lactococcus cremoris associated with consumption of unpasteurized milk. Treatment with amoxicillin-clavulanic acid and subsequently penicillin resulted in prompt sterilization of this patient's bloodstream and full recovery.

Elevation of Lactococcus lactis subsp. cremoris to the species level as Lactococcus cremoris sp. nov. and transfer of Lactococcus lactis subsp. tructae to Lactococcus cremoris as Lactococcus cremoris subsp. tructae comb. nov.

International Journal of Systematic and Evolutionary Microbiology, 2019
Currently, Lactococcus lactis contains four subspecies: L. lactis subsp. lactis ,

Autolysis of Lactococcus lactis

International Dairy Journal, 2002
Abstract During cheese making, autolysis of Lactococcus lactis starter bacteria affects cheese flavour development through release of intracellular enzymes. The gene for the major autolysin in L. lactis, N-acetyl muramidase (AcmA), has been cloned and sequenced. The activity of AcmA alone, however, does not explain the huge variation in the extent of

[Lactococcus garvieae endocarditis].

Nederlands tijdschrift voor geneeskunde, 2015
Lactococcus garvieae, a Gram-positive lactococcus with a short incubation period and high virulence, is a known fish pathogen responsible for serious outbreaks in both marine and freshwater aquaculture. The first human infection was documented in 1991. This is the first case report of L.
