Lineages with broad dairy biotope ranges and phenotypic variability in Propionibacterium freudenreichii revealed by multilocus sequence typing
Résumé
Propionibacterium freudenreichii is used as a ripening culture in Swiss cheese and studied for its probiotic potentialities. Despite the reported variety of biotopes and phenotypes in the species, little is known about the P. freudenreichii population structure. The molecular diversity and the relationships between P. freudenreichii strains MLST scheme and sequence diversity were investigated using multilocus sequence typing (MLST)
