Abstract:
Abstract. In previous a study we demonstrated the presence of several genomic subpopulations within a collection of Pediococcus acidilactici strains isolated from different environments, through a multilocus
typing analysis taking into consideration housekeeping conserved loci and protein coding genes of the primary metabolism. In this study, representative strains of five genomic subpopulations previously
described (I, II, III, V, VII) were analyzed by restriction analysis of chromosomal DNA and subsequent hybridization assays using as probes amplified fragments obtained from five housekeeping genes (16S rDNA, rpoC, ldhD, ldhL, and metS). A computer similarity and clustering analysis of hybridization data showed the subdivision of P. acidilactici strains in five distinct genotypes according to the grouping
previously obtained confirming that pediocin AcH/PA-1 producer strains represent one genomic lineage
within the species P. acidilactici.
