Immobilization of Bacteriocins from Lactic Acid Bacteria and Possibilities for Application in Food Biopreservation [PDF]
, 2018 Bacteriocins are biologically active compounds produced by a large number of bacteria, including lactic acid bacteria (LAB), which exhibit antimicrobial activity against various saprophytic and pathogenic microorganisms.

Synthesis and Optimization of Nisin-Silver Nanoparticles at Different Conditions [PDF]
Engineering and Technology Journal, 2015 Silver nitrate and commercial sigma Nisin were used to synthesize Nisin-Silver nanoparticles; different concentrations of Nisin at different pH conditions were used to optimize the characterization.10 μg/ml at pH 6.0 had the greatest observation and the ...

Controlled overproduction of proteins by lactic acid bacteria [PDF]
, 1997 Lactic acid bacteria are widely used in industrial food fermentations, contributing to flavour, texture and preservation of the fermented products. Here we describe recent advances in the development of controlled gene expression systems, which allow the

Nisin Variants Generated by Protein Engineering and Their Properties
Bioengineering, 2022 Nisin, a typical lantibiotic, has robust antimicrobial activity combined with limited cytotoxicity, and the development of resistance to it is slow. These properties make nisin a promising antimicrobial agent to control pathogenic microorganisms in dairy

Novel Mechanism for Nisin Resistance via Proteolytic Degradation of Nisin by the Nisin Resistance Protein NSR [PDF]
Antimicrobial Agents and Chemotherapy, 2009 ABSTRACT Nisin is a 34-residue antibacterial peptide produced by Lactococcus lactis that is active against a wide range of gram-positive bacteria. In non-nisin-producing L. lactis , nisin resistance could be conferred by a specific nisin resistance gene ( nsr

In vitro antagonistic effect of nisin on faecal enterococci and staphylococci
Veterinární Medicína, 2001 Enterococci and staphylococci, isolates from faecal samples of 46 different animals such as deer, chamois, European bison, zebra, camel, antelope, gazelle, horse, and piglets were treated by nisin (concentration 1 mg/ml). Only two strains (SX38 and EA163)

Antimicrobial antagonists against food pathogens; a bacteriocin perspective [PDF]
, 2015 peer-reviewedEfforts are continuing to find novel bacteriocins with enhanced specificity and potency. Traditional plating techniques are still being used for bacteriocin screening studies, however, the availability of ever more bacterial genome sequences

Isolation and identification of Lactococcu lactis producing nisin
浙江大学学报. 农业与生命科学版, 2005 In Lactococcus lactis strains producing nisin, nisin production is encoded by a large conjugative nisin-sucrose transposon including genes involved in immunity to nisin, and under the guidance of this principle, 6 strains were isolated from fresh milk ...

Microbial Cell Factories, 2022 Background The bacteriocin nisin is naturally produced by Lactococcus lactis as an inactive prepeptide that is modified posttranslationally resulting in five (methyl-)lanthionine rings characteristic for class Ia bacteriocins.
