Spectroscopic aspects on the interaction of nisin with serum albumin: thermodynamic and kinetic studies [PDF]

BioImpacts, 2023
Introduction: Nisin is a bacteriocin produced by Streptococcus and Lactococcus species and has antimicrobial activity against other bacteria. Nisin omits the need to use chemical preservatives in food due to its biological preserving properties. Methods:

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

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.
