Inhibition of Aeromonas hydrophila‐induced intestinal inflammation and mucosal barrier function damage in crucian carp by oral administration of Lactococcus lactis

Fish and Shellfish Immunology, 2018
This study explored the immunomodulatory effect and inhibition effects of the candidate probiotic Lactococcus lactis 16‐7, which was isolated from crucian carp, on Aeromonas hydrophila infection in crucian carp.

Fluorescence assessment of Lactococcus lactis viability

International Journal of Food Microbiology, 2000
The reproduction and activity of lactic acid bacteria (LAB) are essential in their applications in the dairy industry and other fermentations. Traditionally used methods like plate counting and acidification tests require long incubation times and provide limited information.

Respiration capacity and consequences in Lactococcus lactis

Antonie van Leeuwenhoek, 2002
We recently reported that the well-studied fermenting bacterium Lactococcus lactis could grow via a respirative metabolism in the presence of oxygen when a heme source is present. Respiration induces profound changes in L. lactis metabolism, and improvement of oxygen tolerance and long-term survival.

Microencapsulation of Lactococcus lactis subsp. cremoris

Journal of Microencapsulation, 1994
Lactococcus lactis subsp. cremoris was microencapsulated within alginate/poly-L-lysine (alg/PLL), nylon or crosslinked polyethyleneimine (PEI) membranes. Toxic effects were observed with solvents and reagents used in nylon and PEI membrane formation. Alg/PLL encapsulation resulted in viable and active cell preparations which acidified milk at a rate ...

Regulation of carbon catabolism in Lactococcus lactis

2000
The Lactococcus lactis IL1403 is a lactose negative, plasmid free strain. Nevertheless, it is able to hydrolyze lactose in the presence of cellobiose.In this work we describe identification of a gene involved in this process. The gene was found to be homologous to the sugar catabolism regulator, ccpA.

Phages of Lactococcus lactis

2005
Abstract Lactococci are Gram-positive mesophilic bacteria with low G-C content that belong to the group of lactic acid bacteria. They are aerotolerant and live by means of fermentation, as they are lacking a respiratory chain, and the main end product during fermentation is lactic acid.

Physiology of pyruvate metabolism in Lactococcus lactis

Antonie van Leeuwenhoek, 1996
Lactococcus lactis, a homofermentative lactic acid bacterium, has been studied extensively over several decades to obtain sometimes conflicting concepts relating to the growth behaviour. In this review some of the data will be examined with respect to pyruvate metabolism.

Heterologous Protein Expression by Lactococcus lactis

2011
This chapter describes the use of Lactococcus lactis as a safe and efficient cell factory to produce heterologous proteins of medical interest. The relevance of the use of this lactic acid bacterium (LAB) is that it is a noncolonizing, nonpathogenic microorganism that can be delivered in vivo at a mucosal level. The use of strains of L.

Membrane Protein Expression in Lactococcus lactis

2009
Membrane proteins play key roles in cellular physiology, and they are important drug targets. Approximately 25% of all genes identified in sequenced genomes are known to encode membrane proteins; however, the majority have no assigned function. Although the resolution of soluble protein structure has entered the high-throughput stage, only 100 high ...
