Enhance nisin yield via improving acid-tolerant capability of Lactococcus lactis F44
Traditionally, nisin was produced industrially by using Lactococcus lactis in the neutral fermentation process. However, nisin showed higher activity in the acidic environment. How to balance the pH value for bacterial normal growth and nisin activity might be the key problem. In this study, 17 acid-tolerant genes and 6 lactic acid synthetic genes were introduced in L. lactis F44, respectively....
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 کاملEnhancement 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 کاملAdverse effect of nisin resistance protein on nisin-induced expression system in Lactococcus lactis.
Nisin is a bacteriocin that is widely used as a safe, natural preservative in food products. Nisin-controlled gene expression (NICE) systems and food-grade expression systems with nisin resistance as the selection marker are increasingly attracting attention owing to their food-grade statuses. However, the putative influence of nisin resistance on NICE systems deserves consideration when nisin ...
متن کاملAutoregulation of nisin biosynthesis in Lactococcus lactis by signal transduction.
The post-translationally modified, antimicrobial peptide nisin is secreted by strains of Lactococcus lactis that contain the chromosomally located nisin biosynthetic gene cluster nisABTCIPRKFEG. When a 4-base pair deletion is introduced into the structural nisA gene (delta nisA), transcription of delta nisA is abolished. Transcription of the delta nisA gene is restored by adding subinhibitory a...
