Probiotics and Food associated microorganisms: ecology, molecular and functional characterization, impact on host health
In the agri-food industry, waste disposal of spent media coming from microbial biomass production is a critical point. Thousands of liters of spent media are discarded, even though still rich in sugars, organic acids, proteins, peptides, amino acids and vitamins. It implies a double issue: a waste of nutrients and the high environmental impact of their disposal.
This project is devoted to the recycle and valorization of exhausted industrial media derived from the biomass production of traditional probiotics: spent media will be used as source of purified fractions to enrich or formulate optimized media needed for biomass production of next generation probiotics (NGPs). The effect of media enrichment on the NGPs biomass yield will be assessed and compared to the in-use industrial medium. Media optimization done at laboratory scale, up to 1L-bioreactor, will be followed by a scale-up at industrial level.
