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...
متن کاملIsolation and characterization of Lactococcus lactis subsp. lactis promoters.
DNA fragments with promoter activity were isolated from the chromosome of Lactococcus lactis subsp. lactis. For the isolation, a promoter probe vector based on the cat gene was constructed, which allowed direct selection with chloramphenicol in Bacillus subtilis and L. lactis. Four of the putative promoters (P1, P2, P10, and P21) were analyzed further by sequencing, mapping of the 5' end of the...
متن کاملBacteriocinogenic 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 ...
متن کاملBacteriocin-like substances produced by Lactococcus lactis subsp. lactis CF4MRS isolated from fish intestine: Antimicrobial activities and inhibitory properties
In the present study, evaluation of antimicrobial activities of Lactococcus lactis subsp. lactis CF4MRS bacteriocin-like substances (BLIS) against various fish pathogens was performed using an agar well diffusion assay. The cell-free supernatant (CFS) was first pre-treated using four different bioassays. In the first treatment T1, CFS was treated with catalase, and the pH was adjusted to 6.5 wi...
متن کاملDetection, Purification and Partial Characterization of a Novel Bacteriocin Substance Produced by Lactoccous Lactis Subsp. Lactis B14 Isolated from Boza—bulgarian Traditional Cereal Beverage
Cereals are subjected to fermentation in almost all regions of the world where cereals are consumed as stable food and therefore variety of raw materials and conditions of perspective fermentations are quite large. In these fermentations lactic bacteria are the predominant organisms together with yeasts. Boza is a Bulgarian traditional drink based on cereals widely consumed by people of all age...
