Comparison of metabarcoding taxonomic markers to describe fungal communities in fermented foods
Comparaison des marqueurs taxonomiques de métabarcoding pour décrire les communautés fongiques dans les aliments fermentés
Résumé
Next generation sequencing offers several ways to study microbial communities. For agri-food sciences, identifying species in diverse food ecosystems is key for both food sustainability and food security. The aim of this study was to compare metabarcoding pipelines and markers to determine fungal diversity in food ecosystems, from Illumina short reads. We built mock communities combining the most representative fungal species in fermented meat, cheese, wine and bread. Four barcodes (ITS1, ITS2, D1/D2 and RPB2) were tested for each mock and on real fermented products. We created a database, including all mock species sequences for each .
