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

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.

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.

Casein-breakdown by Lactococcus lactis

1996
Mixed starter cultures used to manufacture Dutch cheeses are composed of lactic acid bacteria of which Lactococcus spp. are the dominant organisms (Hugenholtz 1986). Several metabolic properties of lactococci serve special functions which directly or indirectly have impact on processes such as flavour development and ripening of the cheese (Olson 1990).

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 ...

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.

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 ...
