The aim of the PhD project is to study the microbial assembly and metabolism as affected by abiotic factors, during table olive fermentation, to understand the microbial interaction with the food matrix and to investigate, at last, the metabolic activities of table olives microbiota on gastrointestinal tract and their positive interaction with the human host. For the achievement of proposed goals multi-omics approaches, such as metagenomic, metatranscriptomic, proteomic and metabolomic, will be applied. These culture-independent techniques will allow a higher sophisticated level of microbial and metabolic investigation to identify new biomarkers that could improve the product quality and the human health.
