MOLECULAR IDENTIFICATION AND GENOTYPING OF CIAUSCOLO AUTOCHTHONOUS MICROFLORA: PRELIMINARY STUDY

摘要

The present study reports the results of a preliminary characterization of the bacterial population of Ciauscolo, a typical Italian fermented sausage, traditionally manufactured in Marche region. The bacterial community involved in Ciauscolo fermentation was investigated using both molecular and culturebased methods. The estimation of genotypic intra-species variation of the autochthonous bacteria isolated was also evaluated by using randomly amplified polymorphic DNA (RAPD) analysis and unweighted pairgroup method with arithmetic averages (UPGMA) cluster analysis. Our findings revealed an high diversity of the autochthonous bacterial population investigated, both at species and strain level.
