Lactic acid bacteria (LABs) have been extensively used in fermentation and more recently as probiotics in food products that promote health. Genome sequencing and functional genomics investigations of LABs varieties provide rapid and important information about their diversity and their evolution, revealing a significant molecular basis.This study investigates the whole genome sequences of the Enterococcus faecium genome (HG937697), isolated from the mucus of freshwater fish in Tunisian dams. Genomic DNA was extracted using the Quick-GDNA kit (Zymoresearch) and sequenced using the Illumina HiSeq2500 system. Sequences quality assessment was performed using FastQC software. The complete genome annotation was carried out with the RAST web server then NCBI PGAAP.Results: The Enterococcus faecium R.A73 assembled in 28 contigs consisting of 2,935,283 bps. The genome annotation revealed 2,884 genes in total including 2,834 coding sequences and 50 RNAs containing 3 rRNAs (one rRNA 16s, one rRNA 23s and one rRNA 5s) and 47 tRNAs. Twenty-two genes implicated in bacteriocin production are identified within the Enterococcus faecium R.A73 genome.Conclusions: Data obtained provide insights to further investigate the effective strategy for testing this Enterococcus faecium R.A73 strain in the industrial manufacturing process. Studying their metabolism with bioinformatics tools represents the future challenge and contribution to improving the utilization of the multi-purpose bacteria in food. %G English %2 https://riip.hal.science/pasteur-03550700/document %2 https://riip.hal.science/pasteur-03550700/file/r2.pdf %L pasteur-03550700 %U https://riip.hal.science/pasteur-03550700 %~ RIIP %~ RIIP_TUNIS
