Definitions for lactococcus

Here are all the possible meanings and translations of the word lactococcus.


  1. lactococcus(Noun)

    Any bacterium of the genus Lactococcus


  1. Lactococcus

    Lactococcus is a genus of lactic acid bacteria that were formerly included in the genus Streptococcus Group N1. They are known as homofermentors meaning that they produce a single product, lactic acid in this case, as the major or only product of glucose fermentation. Their homofermentative character can be altered by adjusting cultural conditions such as pH, glucose concentration, and nutrient limitation. They are gram-positive, catalase-negative, non-motile cocci that are found singly, in pairs, or in chains. The genus contains strains known to grow at or below 7˚C. Seven species of Lactococcus are currently recognized along with four subspecies. They are: ⁕L. lactis ⁕L. lactis subsp. lactis ⁕L. lactis subsp. cremoris ⁕L. lactis subsp. hordniae ⁕L. lactis subsp. tructae ⁕L. garvieae ⁕L. plantarum ⁕L. raffinolactis ⁕L. piscium ⁕L. chungangensis ⁕L. fujiensis These organisms are commonly used in the dairy industry in the manufacture of fermented dairy products like cheeses. They can be used in single-strain starter cultures, or in mixed-strain cultures with other lactic acid bacteria such as Lactobacillus and Streptococcus. Special interest is placed on the study of L. lactis subsp. lactis and L. lactis subsp. cremoris, as they are the strains used as starter cultures in industrial dairy fermentations. Their main purpose in dairy production is the rapid acidification of milk; this causes a drop in the pH of the fermented product, which prevents the growth of spoilage bacteria. The bacteria also play a role in the flavor of the final product. Lactococci are currently being used in the biotechnology industry. They are easily grown at industrial scale on cheap whey-based media. As food-grade bacteria, they are used in the production of foreign proteins that are applied to the food industry.

  1. Lactococcus

    A genus of gram-positive, coccoid bacteria mainly isolated from milk and milk products. These bacteria are also found in plants and nonsterile frozen and dry foods. Previously thought to be a member of the genus STREPTOCOCCUS (group N), it is now recognized as a separate genus.
