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...
متن کاملProcessing of byproducts to improve nisin production by Lactococcus lactis
In the last years, disposal from dairy industries have received a special attention due its polluting power in the environment. For this reason, studies have obtained a positive support to develop different alternatives to recycle milk whey components. One of them is its utilization as culture media, aiming to produce biomolecules with noble applications. Nisin is an extracellular peptide, prod...
متن کاملNisin inducible production of listeriolysin O in Lactococcus lactis NZ9000
BACKGROUND Listeria monocytogenes is a well-characterized food-borne pathogen that infects pregnant women and immunocompromised individuals. Listeriolysin O (LLO) is the major virulence factor of the pathogen and is often used as a diagnostic marker for detection of L. monocytogenes. In addition, LLO represents a potent antigen driving T cell-mediated immunity during infection. In the present w...
متن کاملOptimization of cyclodextrin production from sago starch.
Cyclodextrin (CD) is synthesized by bacterial cyclodextrin glycosyltransferase (CGTase) and is widely used in food, pharmaceutical, cosmetic, and agricultural industries. In this study, Bacillus circulans CGTase was partially purified by ammonium sulfate precipitation at 50-70% saturation. The optimum pH and temperature for CD production from sago starch were found to be in the ranges of 4.5-5....
متن کاملIsolation of bacteriocin nisin producing Lactococcus lactis from dairy products
Most inhibitory substances produced by lactic acid bacteria are safe and effective natural inhibitors of pathogenic and food spoilage bacteria in various foods. In this study, bacteriocin nisin producing Lactococcus lactis was isolated from fermented milk and cheese. The test isolate was grown in MRS medium under optimized conditions. Bacteriocin activity of the test isolate was determined by a...
