Interest of using activated chitosan on must as an alternative to sulfites. Evaluation of the abundance and diversity of microbial populations impacted by a chitosan-based treatment on must, using targeted metagenomics. Vanille-Charlotte ACHAINTRE1, Antoine GOBERT1, Marie-Sarah EVERS1, Céline SPARROW1 1Groupe SOFRALAB® - 79 av. A.A. Thevenet, 51530 MAGENTA, FRANCE INTRODUCTION RESULTS & DISCUSSION Reducing the sulfite additions in enology has been at the core of technical concerns for several years. To date, there is no existing product or process that alone is technically capable of fully replacing SO2. 1 2 Chitosan, a molecule with well-known antimicrobial properties, has proven Total flora to be of particular interest in this area. It is a polysaccharide from the Another tool used to study diversity is the Shannon index. This glycosaminoglycan family, obtained by deacetylation of chitine extracted The result of targeted metagenomics is the OTUs (operational taxonomic unit) table. Th
