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

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 ...

The Analysis of Field Strains Isolated From Food, Animal and Clinical Sources Uncovers Natural Mutations in Listeria monocytogenes Nisin Resistance Genes

Frontiers in Microbiology, 2020
Nisin is a commonly used bacteriocin for controlling spoilage and pathogenic bacteria in food products. Strains possessing high natural nisin resistance that reduce or increase the potency of this bacteriocin against Listeria monocytogenes have been ...

Innovative approaches to nisin production [PDF]

Applied Microbiology and Biotechnology, 2018
Nisin is a bacteriocin produced by Lactococcus lactis that has been approved by the Food Drug Administration for utilization as a GRAS status food additive. Nisin can inhibit spore germination and demonstrates antimicrobial activity against Listeria, Clostridium, Staphylococcus, and Bacillus species.

Nisin S, a Novel Nisin Variant Produced by Ligilactobacillus salivarius P1CEA3

International Journal of Molecular Sciences, 2023
Recently, the food industry and the animal farming field have been working on different strategies to reduce the use of antibiotics in animal production. The use of probiotic producers of antimicrobial peptides (bacteriocins) is considered to be a potential solution to control bacterial infections and to reduce the use of antibiotics in animal ...

Application of an Alternative Inorganic Acid Antimicrobial for Controlling Listeria monocytogenes in Frankfurters

Frontiers in Sustainable Food Systems, 2019
The prevalence of Listeria monocytogenes under refrigerated conditions is a concern for ready to eat meats like Frankfurters. The purpose of this study was to evaluate the bactericidal effect of potential antimicrobials, Bisulfate of Soda (SBS), nisin ...

The detection, characterization, and quantification of dominant degradation products of nisin A and Z in selected dairy products by liquid chromatography–high-resolution mass spectrometry technique

JDS Communications
Nisin, a bacteriocin produced through fermentation using bacterium Lactococcus lactis, has several commercial variants such as nisin A and nisin Z. Nisin serves as a natural preservative with antimicrobial properties in various food products, including ...

Identifying Cytokine Motif‐Containing, Immunomodulatory Bacterial Proteins in Human Gut Microbiome

Advanced Science, EarlyView.
By building and constructing HMM (Upper left, blue), the authors identify CMCPs in bacteria genomes and CRC related metagenomes and enriched CRC‐related CMCPs (Upper right, blue). They analyze sequence and structural similarity of hits (Lower left, green), test function with engineered EcN delivered to tumors in a mouse tumor model (Lower right, pink ...

Current Advancements of Probiotic Foods and Their Role in Sustainable Food Security

Food Bioengineering, EarlyView.
ABSTRACT Probiotic foods have evolved from traditional fermented products to scientifically validated functional foods, defined by the FAO and WHO as live microorganism that confer a health benefit on the host when administered in adequate amounts, with effects being strain, does and end point specific.

Antibacterial Effect of High-Purity Nisin Alone and in Combination with D-Amino Acids or Chlorhexidine in an Endodontic-Like Biofilm Model

Antibiotics, 2021
New strategies to eradicate endodontic biofilms are needed. Therefore, we evaluated the effect of high-purity nisin alone and in combination with D-amino acids (D-AAs) or chlorhexidine (CHX) against an “endodontic-like” biofilm model. Biofilms were grown
