Lactococcus Lactis subsp. cremoris Elicits Protection Against Metabolic Changes Induced by a Western-style Diet.

Gastroenterology, 2020
BACKGROUND & AIMS A Western-style diet, which is high in fat and sugar, can cause significant dyslipidemia and non-alcoholic fatty liver disease; the diet has an especially strong effect in women, regardless of total calorie intake.

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.

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

Protective effects of a novel probiotic strain, Lactococcus lactis ML2018, in colitis: in vivo and in vitro evidence.

Food & Function, 2019
Multiple articles have confirmed that an imbalance of the intestinal microbiota is closely related to aberrant immune responses of the intestines and to the pathogenesis of inflammatory bowel diseases (IBDs).

Restriction-modification systems in lactococcus lactis

Gene, 1995
Several restriction-modification (R-M) systems have been identified in Lactococcus lactis. Most of the systems have been plasmid encoded and function as phage-resistance mechanisms. At least five different type-II R-M systems, LlaAI, LlaBI, LlaCI, LlaDI and LlaEI, were identified in isolates from a mixed Cheddar starter culture.

Using Lactococcus lactis for glutathione overproduction

Applied Microbiology and Biotechnology, 2004
Glutathione and gamma-glutamylcysteine were produced in Lactococcus lactis using a controlled expression system and the genes gshA and gshB from Escherichia coli encoding the enzymes gamma-glutamylcysteine synthetase and glutathione synthetase. High levels of gamma-glutamylcysteine were found in strains growing on chemically defined medium and ...

Enhancement of Nisin Production by Lactococcus lactis subsp. lactis

Probiotics and Antimicrobial Proteins, 2016
Lactococcus lactis subsp lactis BSA (L. lactis BSA) was isolated from a commercial fermented product (BSA Food Ingredients, Montreal, Canada) containing mixed bacteria that are used as starter for food fermentation. In order to increase the bacteriocin production by L. lactis BSA, different fermentation conditions were conducted.

Electrotransformation of Lactococcus lactis

2000
The last decade has seen a spectacular increase in genetic technology of Lactococcus lactis, the model lactic acid bacterium extensively used as starter culture in the manufacture of dairy products. The development of transformation techniques (Gasson & Fitzgerald 1994) and construction of powerful plasmids for gene cloning (de Vos & Simons 1994), as ...
