Project description:Fermented foods are microbial ecosystems in which bacteria and fungi convert raw ingredients into stable, nutritious, and health-promoting products. The composition and activity of these microorganisms determine the biochemical and nutritional profile of the final food. We analyzed 17 fermented foods, each in triplicate, using metaproteomics. This analysis revealed that microbial proteins contribute up to 11% of total protein and 60% of identified proteins. Detailed information on file-naming conventions (database files, MS raw files, and output files), as well as food source suppliers, fermenting microorganisms, peptide loading volumes, and LC-MS gradient lengths, is provided in the table FileAndSampleDescription_PRIDE_submission.csv.

Project description:Bacterial community in fermented soyabean food
Project description:Mycotoxin citrinin (CTN) is a contaminant widely found in foods, feeds, and fermented health supplements. To investigate the potential neurotoxic effect of CTN, RNA-seq was performed on human neuroblastoma cells SH-SY5Y exposed to 0, 10, and 20 μM CTN for 72 h. The transcriptomic profile revealed novel underlying mechanisms of CTN neurotoxicity, providing useful information for risk assessment of consuming CTN-contaminated grains and its commercial food products.
Project description:Nowadays, Western diets and lifestyle lead to an increasing occurrence of chronic gut inflammation, that represents an emerging health concern with still a lack of successful therapies. Fermented foods, and their associated Lactic Acid Bacteria, have recently regained popularity for their probiotic potential including the maintenance of gut homeostasis by modulating the immune and inflammatory response. Our study aims to investigate the cross-talk between the food-borne strain Lactiplantibacillus plantarum C9O4 and intestinal epithelial cells in an in vitro inflammation model. Cytokines profile shows the ability of C9O4 to significantly reduce levels of IL-2, IL-5, IL-6, and IFN-γ. Proteomic functional analysis reveals an active host-microbe interaction that highlights an immunoregulatory role of C9O4, able to revert both the detrimental effects of IFN-γ through the JAK/STAT pathway and the apoptosis process in inflamed cells. These results suggest a promising therapeutic role of fermented food-associated microbes for the management of gastrointestinal inflammatory diseases.
