Descrizione:
The present thesis project focuses on the study of the microbiota of cooked ham and raw sausage packaged in modified atmosphere (MAP), with the aim to obtain new data which will be used to reduce the spoilage process. The microbiota was analyzed through a combination of culture-dependent and independent methods. The latter relies on a NGSbased metagenomic approach, which is essential to get a more comprehensive overview of complex ecosystems such as the meat microbiota. It relies on the sequencing of the specific 16S rRNA region and it is implemented by using the Illumina platform. The analysis and the taxonomic characterization of sequences made it possible to obtain data about the number of reads associated to each OTU. The culture-dependent method was based on the isolation of microorganisms on selective medium plates, on RAPD-PCR clustering and taxonomic designation by partial sequencing of the 16S gene. The study was completed with an organoleptic and volatile organic compounds an ...
