Research Unit BioDyMIA

BioDyMIA is developing activities from basic research to applicative goals, thorough studying the mechanisms involved in the biopreservation of foods. Biopreservation concepts are based on the exploitation of the antimicrobial activity of natural extracts, molecules or biological agents (microorganisms such as those contributing to the preservation of traditional fermented foods or bacteriophages). This allows BioDyMIA to propose innovative approaches inspired from the observation of interactions between microorganisms and their environment.

Finding application fields of these innovative biopreservation routes implies:
• In-depth understanding of the mechanisms of biopreservation of traditional foods
• Design of innovative materials to improve food microbial safety (for example antimicrobial packaging).
