Research topic
Foods as reservoir of novel starter, probiotic and human commensal microorganisms: ecology, molecular and functional characterization, and impact on host health
Project Synopsis
The scope of my research is to characterise and compare microbial communities associated with different commercially available rocket salad products, in order to verify whether farming and processing methods are affecting the microbial load diversity. A complete antibiotic resistance profile will be produced, and a library of selected lactic acid bacteria will be created to eventually design a novel and reinforced RTE salad. This project will then investigate the role that modern dietary regimens – with little fermented foods and large quantities of highly processed goods – might play in the increasing incidence of autoimmune diseases and allergic disorders. The basis for a new branch of research on microorganisms and their importance in daily food intake will therefore be set.
