Bacteriocin associated genes in french and ukrainian fermented vegetable isolates of lactiplantibacillus plantarum

Anotace: Lactiplantibacillus plantarum species is known for the high diversity of the loci encoding bacteriocin (plantaricin) production. The aim of this work was to study the distribution of pln genes in French and Ukrainian isolates of L. plantarum originated from fermented plant material. PCR with the primers to plnA, plnB, plnC, plnD, plnEF, plnI, plnK, plnJ, plnG, plnN, plnW genes was performed to find out the peculiarities of L. plantarum strains. French and Ukrainian isolates shared none of the identical combinations of genes from plantaricin regulon indicating the diversity of pln loci in L. plantarum of fermented plant origin from the distant geographical regions. Certain combinations of genes from plantaricin regulon could be proposed as indicators marking the geographical origin of L. plantarum strains. Among the studied isolates, some resembled the described in the literature L. plantarum strains, and others contained unique combinations of pln genes.
