Lactococcus lactis cholangitis and bacteremia identified by MALDI-TOF mass spectrometry: A case report and review of the literature on Lactococcus lactis infection

Journal of Infection and Chemotherapy, 2019
Lactococcus lactis is a rare causative organism in humans. Cases of L. lactis infection have only rarely been reported. However, because it is often difficult to identify by conventional commercially available methods, its incidence may be underestimated.

Improving nisin production by encapsulated Lactococcus lactis with starch/carboxymethyl cellulose edible films.

Carbohydrate Polymers, 2021
In this study, Lactococcus lactis was embedded in a film of corn starch (NS) and carboxymethyl cellulose (CMC) prepared using a casting method. At a CMC:NS ratio of 5:5, the composite film had the best comprehensive properties.

Effects of dietary host-associated Lactococcus lactis on growth performance, disease resistance, intestinal morphology and intestinal microbiota of mandarin fish (Siniperca chuatsi)

Aquaculture, 2021
This study was conducted to evaluate the effects of dietary host-associated Lactococcus lactis 3-c-18 supplementation on the growth, serum biochemical indices, liver and intestine health, intestinal microbiota, and Aeromonas hydrophila resistance in ...

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.

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.

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.

Effects of Lactococcus lactis from Cyprinus carpio L. as probiotics on growth performance, innate immune response and disease resistance against Aeromonas hydrophila.

Fish and Shellfish Immunology, 2019
In the present study, we reported 18 LAB strains isolated from the intestinal contents of Cyprinus carpio, and their probiotic properties both in vitro and in vivo.

Physical and antimicrobial properties of edible films containing Lactococcus lactis.

International Journal of Biological Macromolecules, 2019
In this study, we developed edible films designed to control the growth of Staphylococcus aureus in tryptone soya agar. We analyzed three edible film-forming substrates: sodium alginate, sodium carboxymethylcellulose, and collagen.

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
