Abstract

Isolation and identification of a gene encoding for a bacteriocin precursor in Pediococcus acidilactici, cloning of the gene in a vector plasmid and transformation to bacteria is described. The bacteriocin is particularly useful for inhibiting Listeria in food products.

Claims1

Dependent claims

A bacteriocin precursor that is essentially free of other proteins and having an amino acid sequence as given in FIG. 4 that corresponds to ORF1, and modifications thereof that still have the capability of being converted into an active bacteriocin.

Dependencies are inferred from the claim text.
