Inediibacterium massiliense gen. nov., sp nov., a new bacterial species isolated from the gut microbiota of a severely malnourished infant

Résumé

A novel strain, Mt12(T) (=CSUR P1907 = DSM 100590), was isolated from the fecal sample of a 7-month-old girl from Senegal afflicted with severe acute malnutrition. This bacterium is a strictly anaerobic, spore-forming Gram-stain positive bacillus. The major cellular fatty acid was identified as tetradecanoic acid. Its 16S rRNA gene sequence exhibited 94.9% similarity with that of Crassaminicella profunda strain Ra1766H(T), currently the closest species with a validly published name. The draft genome of strain Mt12(T) is 3,497,275-bp long with a 30.45% of G+C content. 3397 genes were predicted, including 3268 protein-coding genes and 129 RNAs, including eight 16S rRNAs. Genomic comparison with closely related species with an available genome showed a lower quantitative genomic content. The phylogenetic analysis alongside the dDDH values under 30% and phenotypic characteristics suggest that strain Mt12(T) represents a new genus within the family Clostridiaceae, for which the name Inediibacterium massiliense gen. nov., sp. nov. is proposed.
