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 ...

Dynamics of pyruvate metabolism in Lactococcus lactis

Biotechnology and Bioengineering, 2001
AbstractThe pyruvate metabolism in the lactic acid bacterium Lactococcus lactis was studied in anaerobic cultures under transient conditions. During growth of L. lactis in continuous culture at high dilution rate, homolactic product formation was observed, i.e., lactate was produced as the major end product.

Membrane Protein Expression in Lactococcus lactis

2015
The Gram-positive bacterium Lactococcus lactis has many properties that are ideal for the overproduction of membrane proteins in a functional form. Growth of lactococci is rapid, proceeds to high cell densities, and does not require aeration, which facilitates large-scale fermentation.

Regulation of proteinase synthesis in Lactococcus lactis

Acta Biotechnologica, 1993
AbstractThe synthesis of extracellular serine proteinase of Lactococcus lactis was studied during the growth in a batch and a continuous culture on chemically defined media. In a batch culture the proteinase synthesis started during the exponential phase of growth and the highest proteinase concentrations were found at the end of the exponential and ...

Growth stimulation of a proteinase positive Lactococcus lactis strain by a proteinase negative Lactococcus lactis strain

International Journal of Food Microbiology, 2007
Lactococcus lactis AMP15/pAMP31(D471R) is a proteinase negative, lactose negative strain with a modified oligopeptide transport system, and potential as a debittering agent due to its efficient utilization of hydrophobic peptides. Five wild L. lactis strains of dairy origin, which produced cheeses of high flavour quality, were cocultured with L. lactis

Bacteriocins Produced By Lactococcus Lactis Strains

1994
The ability of some lactococci to produce inhibitory substances other than organic acids has been known for quite some time. These substances include the well-known bacteriocins nisin (Hurst, 1981; Rayman & Hurst, 1984) and diplococcin (Davey & Pearce, 1982), the lactostrepcins (Kozak et al., 1978) and lactococcins (Van Belkum et al., 1989, 1991, 1992)

Optimization of Nisin Production by Lactococcus lactis

2002
The production of nisin by batch culture of Lactococcus lactis ATCC 11454 in MRS broth (pH 6.5), as treated in 30 assays, that were set up by a fractional factorial design of two levels (2[4-1]), was improved. The minimum and maximum concentrations of sucrose (5.0-12.5 g/L), asparagine (7.5-75 g/L), potassium phosphate (6.0-18.0 g/L), and Tween-80 (1.0-

Lactococcus lactis CodY

2006
Melkzuurbacteriën breken melkeiwitten af, wat belangrijk is voor de smaakvorming van kaas. De bacteriën groeien in melk en gebruiken de daarin aanwezige eiwitten als voedingsbron. Het zogenaamde proteolytisch systeem van de bacteriën zorgt voor de afbraak van de melkeiwitten en de opname en verwerking van de afbraakproducten.
