Taxonogenomic description of four new Clostridium species isolated from human gut: 'Clostridium amazonitimonense', 'Clostridium merdae', 'Clostridium massilidielmoense' and 'Clostridium nigeriense'

Culturomics investigates microbial diversity of the human microbiome by combining diversified culture conditions, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and 16S rRNA gene identification. The present study allowed identification of four putative new Clostridium sensu stricto species: ‘Clostridium amazonitimonense’ strain LF2^T, ‘Clostridium massilidielmoense’ strain MT26^T, ‘Clostridium nigeriense’ strain Marseille-P2414^T and ‘Clostridium merdae’ strain Marseille-P2953^T, which we describe using the concept of taxonogenomics. We describe the main characteristics of each bacterium and present their complete genome sequence and annotation.

Noncontiguous finished genome sequences and description of Bacillus massiliglaciei, Bacillus mediterraneensis, Bacillus massilinigeriensis, Bacillus phocaeensis and Bacillus tuaregi, five new species identified by culturomics

Microbial culturomics, which investigates microbial diversity by combining diversified culture conditions, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and 16S rDNA identification, allowed to identify five new species within the Bacillus genus. Bacillus massiliglaciei strain Marseille-P2600^T, Bacillus mediterraneensis strain Marseille-P2384^T, Bacillus massilinigeriensis strain Marseille-P2366^T, Bacillus tuaregi strain Marseille-P2489^T and Bacillus phocaeensis strain SIT16^T are each the type strain of the corresponding bacterial species. These strains, the genomes of which are described here, are facultative anaerobic Gram-positive bacilli. Here, we describe the main characteristics of each bacterium and present their complete genome sequence and annotation.

Genome sequence and description of Anaeromassilibacillus senegalensis gen. nov., sp. nov., isolated from the gut of patient with kwashiorkor

Using the culturomics strategy, a wide range of anaerobic bacteria was discovered including Anaeromassilibacillus senegalensis strain mt9^T (= CSUR P1511 = DSM 102954), isolated from the gut microbiota of a 1-year-old Senegalese patient with kwashiorkor. This Gram-negative strain is a strictly anaerobic, spore-forming rod motile by a polar flagellum. The 3 511 289 bp long genome of this strain contains 3046 protein-coding and 49 RNA genes, including 45 tRNA and four rRNA genes, and exhibits a G+C content of 52.94%. Here we describe the features of this organism, together with the complete genome sequence and annotation.

"Bacillus mediterraneensis," a new bacterial species isolated from human gut microbiota

We present a brief description of “Bacillus mediterraneensis” strain Marseille-P2366^T (= CSUR P2366 = DSM 102091), a new species isolated from the gastrointestinal tract of a healthy 13-month-old boy from Senegal.
