Bacterial community composition determined by 16S rRNA gene amplicon sequencing. Species detected in Raclette du Valais PDO cheese DNA samples (S01-S21) with an average relative abundance above 0.5% are shown in the upper panel and the species with a lower average abundance in the lower panel. The relative abundance of the 21 species detected in more than 30% of the samples are depicted with the species name; the other 26 taxa were classified as other species
