Abstract
Strain Marseille-P2082, an anaerobic, non-motile, asporogenous, Gram-negative, coccoid bacterium was isolated from the faeces of a 33 year-old obese French woman before bariatric surgery. The isolate exhibits 98.65% 16S rRNA gene nucleotide sequence similarity with Negativicoccus succinicivorans strain ADV 07/08/06-B-1388T, its current closest phylogenetic neighbour with standing in nomenclature. However, the dDDH relatedness between the new isolate and N. succinicivorans type strain ADV 07/08/06-B-1388T is 52.5 ± 2.7%. Strain Marseille-P2082 has a genome of 1,360,589 bp with a 51.1% G+C content. Its major fatty acids were identified as C18:1n9, C18:0 and C16:0. Based on its phenotypic, genomic and phylogenetic characteristics, strain Marseille-P2082T [= CSURP2082 (Collection de Souches de l’Unité des Rickettsies) = DSM 100853] is proposed as the type strain of the novel species Negativicoccus massiliensis sp. nov. The 16S rRNA gene sequence and whole-genome shotgun sequence have been deposited in EMBL-EBI under accession numbers LN876651 and LT700188, respectively.
