Metabarcoding analysis and fermentation performance of the dominant fungal microbiota associated with the Algerian traditional date product "Btana".

The study highlights the fungal diversity of the traditional Algerian date's product "Btana" prepared with direct Btana method (DBM) and undirect Btana method (UBM). Btana fungal populations were analyzed through 28S metabarcoding. Data treatment resulted in 122,997 reads representing three Phyla in which 76% reads (46 OTUs) belong to Ascomycota phylum.
