Abstract

Using microbial culturomics, we were able to isolate strain Marseille-P3078 from a stool sample of a healthy 50-year-old Saudi Arabian woman. To this end, we used taxonogenomics that combines phenotypic, biochemical and genomic analyses, to describe this bacterium. Cells from strain Marseille-P3078 are anaerobic and Gram-negative rods that are motile and unable to sporulate. Its genome size is 3,377,914-bp-long with a 66.33 mol% G + C content. Based on its phenotypic and genomic features, including a 94.6% 16S rRNA similarity with Paraeggerthella hongkongensis strain JCM 14552, its closest phylogenetic neighbor withstanding in nomenclature, we propose that strain Marseille-P3078T (= CSUR P3078 = DSM 104007) is the representative strain of a new genus for which we propose the name Arabiibacter massiliensis gen. nov., sp. nov.
