Symbiotic microencapsulation of Lactococcus lactis subsp. lactis R7 using whey and inulin by spray drying

LWT, 2019
This study was conducted to characterize autochthonous Lactococcus lactis subsp. lactis R7 (L. lactis R7) microencapsulated with whey and inulin by spray drying and evaluate the microencapsulation's ability to protect against adverse conditions ...

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).

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.

Nisin-producing Lactococcus lactis subsp. lactis 2MT isolated from freshwater Nile tilapia in Cameroon: Bacteriocin screening, characterization, and optimization in a low-cost medium

LWT, 2019
This work was aimed to isolate bacteriocin-producing lactic acid bacteria (LAB) from freshwater fish in Cameroon, characterize the bacteriocin and investigate its production as well as growth optimization in low-cost media. From the 144 isolates obtained,

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 ...

Antagonistic activity of recombinant Lactococcus lactis NZ1330 on the adhesion properties of Escherichia coli causing urinary tract infection.

Microbial Pathogenesis, 2019
Death from infectious diseases has caused concerns about increases in the resistance of pathogens, impelling researchers to create novel therapeutic solutions. The management of intestinal tract problems has been the advance use of probiotics in medicine.

Fermented soymilk with a monoculture of Lactococcus lactis

International Journal of Food Microbiology, 2003
Lactococcus lactis strain (LL3) isolated from mothers' milk was used to produce fermented soymilk. The strain survived at levels of over 7 log cfu/ml for 3 weeks in the fermented soymilk. A consumer survey was carried out to compare the acceptability of the fermented product with a similar product made with L.

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 ...

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.
