Minimal Requirements for Exponential Growth of Lactococcus lactis

Minimal Requirements for Exponential Growth of Lactococcus lactis.

A minimal growth medium containing glucose, acetate, vitamins, and eight amino acids allowed for growth of Lactococcus lactis subsp. lactis, with a specific growth rate in batch culture of mu = 0.3 h. With 19 amino acids added, the growth rate increased to mu = 0.7 h and the exponential growth phase proceeded until high cell concentrations were reached. We show that morpholinepropanesulfonic ac...

Cloning of EprA1 gene of Aeromonas hydrophila in Lactococcus lactis

Bacterial-based systems as live vectors for the delivery of heterologous antigens offer a number of advantages as vaccination strategies. Developments in genetic engineering have given Gram-positive lacticacid bacteria (LAB) the advantage of being used as a host expression system for antigen delivery to inducethe immune response. A fragment containing the full length of the “eprA1” ...

Taxonomy, physiology and growth of Lactococcus lactis: a review

Lactococcus lactis species is one of the most important groups of lactic acid bacteria that are used in the dairy industry. The major functions of this species in dairy fermentation are the production of lactic acid from lactose, hydrolysis of casein and citric acid fermentation. Thus their metabolic end products and enzymes directly or indirectly have significant influence in determining the t...

Lactococcus lactis as a live delivery vector

Mucosal surfaces of the body provide a universal entry portal for all known and emerging infectious pathogenic microbes. Therefore, it seems that special vaccination strategies are needed for vaccines that can hinder the entry capability of pathogenic microbes through the mucosal surfaces. Lactic acid bacteria are widely used in the food industry and are presently applied as delivery vehicles i...
