Synthesis and Optimization of Nisin-Silver Nanoparticles at Different Conditions [PDF]

open access: yesEngineering 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 ...

Susceptibility of bifidobacteria to nisin [PDF]

open access: yesLetters in Applied Microbiology, 1998
A collection of 17 bifidobacteria was tested for sensitivity or resistance to lantibiotic nisin. Minimal inhibitory concentration of the strain tested was highly variable, ranging from 4.88 to 10,000 IU-1. In general, strains isolated from faecal samples were more resistant than those purchased from culture collections. These results could be useful in

Nisin as a Novel Feed Additive: The Effects on Gut Microbial Modulation and Activity, Histological Parameters, and Growth Performance of Broiler Chickens

open access: yesAnimals, 2020
Two independent experiments were performed to evaluate the effect of nisin alone or with monensin on gut microbiota, gut microbial activities, and histomorphology (exp 1) and the effect of nisin application in a dose‒response manner on the growth ...

Recombinant production of the lantibiotic nisin using Corynebacterium glutamicum in a two-step process

open access: yesMicrobial 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.

Nisin Variants Generated by Protein Engineering and Their Properties

open access: yesBioengineering, 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

Isolation and identification of Lactococcu lactis producing nisin

open access: yes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 ...

Nisin Mutant Prevention Concentration and the Role of Subinhibitory Concentrations on Resistance Development by Diabetic Foot Staphylococci

open access: yesAntibiotics, 2022
The most prevalent microorganism in diabetic foot infections (DFI) is Staphylococcus aureus, an important multidrug-resistant pathogen. The antimicrobial peptide nisin is a promising compound for DFI treatment, being effective against S. aureus. However,
