Individuazione e tipizzazione polifasica di ecotipi funzionali di batteri lattici coinvolti nelle produzioni casearie italiane

This PhD thesis dealt with the phenotypic and genotypic characterization of LAB strains through a polyphasic taxonomic approach, molecular analyses such as PCR, ITS, ARDRA, the study of housekeeping genes, search and classification of plasmidic DNA. The integration of the phenotypic, biotechnological and genotypic results allowed the obtainment of fingerprinting specific at the strain-level and the possible discrimination of the strains in function of their ecological niches.
