Selection of influential parameters for bacteriocin production by Lactococcus lactis subsp. lactis R10 by Plackett- Burman design

Enhancement of Nisin Production by Lactococcus lactis subsp. lactis.

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. They included different volumetric combinations of two culture me...

Folate Production by Lactococcus lactis

Bacteriocin-Producing Strain of Lactococcus lactis subsp. diacitilactis S50.

Lactococcus lactis subsp. diacitilactis S50 produces a bacteriocin, designated bacteriocin S50, which has a narrow antibacterial spectrum. It was active only against Lactococcus species, including a nisin producer exhibiting a bactericidal effect. The activity of bacteriocin S50 was sensitive to proteases. It retained antimicrobial activity after being heated to 100 degrees C for up to 60 min a...

Bacteriocinogenic Lactococcus lactis subsp. lactis DF04Mi isolated from goat milk: Characterization of the bacteriocin

Lactic acid bacteria capable of producing bacteriocins and presenting probiotic potential open innovative technological applications in the dairy industry. In this study, a bacteriocinogenic strain (Lactococcus lactis subsp. lactis DF4Mi) was isolated from goat milk, and studied for its antimicrobial activity. The bacteriocin presented a broad spectrum of activity, was sensitive to proteolytic ...

An evaluation and partial characterization of a bacteriocin produced by Lactococcus lactis subsp lactis ST1 isolated from goat milk

A bacteriocin-like inhibitory substance producing Lactococcus lactis subsp lactis strain, ST1, isolated from goat milk of Iranian origin and with broad spectrum of activity and desirable technical properties was used for evaluating some futures of bacteriocin inhibitory activity. Cell growth and bacteriocin production studies were carried out in MRS medium incubated statically under uncontrolle...
