Lantibiotics are peptide-derived antimicrobial agents that are ribosomally synthesized and
posttranslationally modified to their biologically active forms. The name lantibiotics was …

Lactococcus lactis is a Gram-positive lactic acid bacterium that, in addition to its traditional
use in food fermentations, is increasingly used in modern biotechnological applications. In …

While lactic acid producing fermentation has been utilized to improve the storability,
palatability, and nutritive value of perishable foods for a very long time, only recently have …

While intercellular communication systems in Gram-negative bacteria are often based on
homoserine lactones as signalling molecules, it has been shown that autoinducing peptides …

Lantibiotics are produced by a variety of Gram-positive bacteria. The production of these
peptides appears to be regulated at the transcriptional level in a cell-density-dependent …

Enterococcus faecalis is among the predominant causes of nosocomial infections. Surface
molecules like d-alanine lipoteichoic acid (LTA) perform several functions in gram-positive …

A set of shuttle vectors, able to replicate in Escherichia coli and in gram-positive bacteria,
containing a nisin-inducible promoter (PnisA) and genes encoding NisR and NisK, the two …

The lactic acid bacteria (LAB) are a functionally related group of low-GC Gram-positive
bacteria known essentially for their roles in bioprocessing of foods and animal feeds. Due to …

We developed a series of ligand-inducible riboswitches that control gene expression in
diverse species of Gram-negative and Gram-positive bacteria, including human pathogens …

The bacterial heat shock response is characterized by the elevated expression of a number
of chaperone complexes. Two-dimensional polyacrylamide gel electrophoresis revealed …
