The increasing use of probiotics in dietary supplements and functional foods highlights the need for robust analytical strategies to assess microbial viability, functional performance, and safety. Conventional culture-based methods may underestimate probiotic potential, particularly in multi-strain formulations. In this study, a multi-analytical framework was applied to evaluate four commercial formulations containing Lactobac...

Onion skins, actually recycled as organic fertilizers, could be used as a substrate in environmental-friendly bioprocesses to recover high-value bioactive compounds and food ingredients. In this work, a bioprospecting method was carried out including 94 bacterial and 45 yeast strains from several agri-food and environmental niches to verify their ability to grow on onion skins as unique nutrients source. Red and yellow onion s...
