Culturomics has recently allowed the isolation and description of previously uncultured bacteria from the human microbiome at different body sites. As part of a project aiming to describe the human gut microbiota by culturomics, Phoenicibacter congonensis strain Marseille-P3241 T was isolated from the gut of a 45 years old Pygmy female. In the present work, we aim to describe this strain via the taxonogenomics approach. The major phenotypic, genomic and biochemical characteristics of this strain were analysed. Strain Marseille-P3241 T is an anaerobic, Gram-positive and motile coccobacillus that grows optimally at 37 °C. The genome of strain Marseille-P3241 T is 1,447,956 bp long with 43.44% GC content and its 16S rRNA gene sequence exhibited 89% sequence similarity with that of Denitrobacterium detoxificans strain NPOH1 T , the phylogenetically closest related species with current standing in nomenclature. After performing a phylogenetic and genomic analysis, we conclude that strain Marseille-P3241 T (= CCUG 70681 T  = CSUR P3241 T ) represents the type species of a new genus, for which we propose the name Phoenicibacter congonensis gen. nov., sp. nov.

The family Rickettsiaceae currently includes two genera: Orientia that contains one species, Orientia tsutsugamushi, and Rickettsia that contains 28 species. Occidentia massiliensis gen. nov., sp. nov. strain OS118(T) is the type strain of O. massiliensis gen. nov., sp. nov., the type species of the new genus Occidentia gen. nov. within the family Rickettsiaceae. This strain, whose genome is described here, was isolated in France from the soft tick Ornithodoros sonrai collected in Senegal. O. massiliensis is an aerobic, rod-shaped, Gram-negative, obligate intracellular bacillus that may be cultivated in BME/CTVM2 cells. Here we describe the features of O. massiliensis, together with the complete genomic sequencing and annotation. The 1,469,252 bp long genome (1 chromosome but no plasmid) contains 1,670 protein-coding and 41 RNA genes, including one rRNA operon.

Collinsella massiliensis strain GD3(T) is the type strain of Collinsella massiliensis sp. nov., a new species within the genus Collinsella. This strain, whose genome is described here, was isolated from the fecal flora of a 53-year-old French Caucasoid woman who had been admitted to intensive care unit for Guillain-Barré syndrome. Collinsella massiliensis is a Gram-positive, obligate anaerobic, non motile and non sporulating bacillus. Here, we describe the features of this organism, together with the complete genome sequence and annotation. The genome is 2,319,586 bp long (1 chromosome, no plasmid), exhibits a G+C content of 65.8% and contains 2,003 protein-coding and 54 RNA genes, including 1 rRNA operon.

Holdemania massiliensis strain AP2(T) sp. nov. is the type strain of H. massiliensis sp. nov., a new species within the genus Holdemania. This strain, whose genome is described here, was isolated from the fecal flora of a 21-year-old French Caucasian female suffering from severe restrictive anorexia nervosa. H. massiliensis is a Gram-positive, anaerobic bacillus. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 3,795,625 bp-long genome (one chromosome but no plasmid) contains 3,461 protein-coding and 49 RNA genes, including 3 rRNA genes.

Brevibacillus massiliensis strain phR(T) sp. nov. is the type strain of B. massiliensis sp. nov., a new species within the genus Brevibacillus. This strain was isolated from the fecal flora of a woman suffering from morbid obesity. B. massiliensis is a Gram-positive aerobic rod-shaped bacterium. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 5,051,018 bp long genome (1 chromosome but no plasmid) contains 5,051 protein-coding and 84 RNA genes, and exhibits a G+C content of 53.1%.

Peptoniphilus obesi strain ph1(T) sp. nov., is the type strain of P. obesi sp. nov., a new species within the genus Peptoniphilus. This strain, whose genome is described here, was isolated from the fecal flora of a 26-year-old woman suffering from morbid obesity. P. obesi strain ph1(T) is a Gram-positive, obligate anaerobic coccus. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 1,774,150 bp long genome (1 chromosome but no plasmid) contains 1,689 protein-coding and 29 RNA genes, including 5 rRNA genes.

Aeromicrobium massiliense strain JC14(T)sp. nov. is the type strain of Aeromicrobium massiliense sp. nov., a new species within the genus Aeromicrobium. This strain, whose genome is described here, was isolated from the fecal microbiota of an asymptomatic patient. Aeromicrobium massiliense is an aerobic rod-shaped gram-positive bacterium. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 3,322,119 bp long genome contains 3,296 protein-coding and 51 RNA genes.
