摘要：
An anaerobic isolate, strain AT7(T), was cultivated from a stool sample of a morbidly obese French woman using a microbial culturomics approach. The 16S rRNA gene sequence analysis showed that strain AT7(T) exhibited 96% nucleotide sequence similarity with Ruminococcus torques strain JCM 6553(T) (=ATCC 27756(T)=VPI B2-51(T)), currently the closest related species with a validly published name. The strain was observed to be a Gram-stain positive, non-motile, asporogenous and coccobacillary-shaped bacterium. It was found to be catalase positive and oxidase negative. Its major fatty acids were identified as C-16:0 (54%) and C-18:1n9 (30%). The draft genome of strain AT7(T) is 3,069,882bp long with 42.4% G+C content. 2925 genes were predicted, including 2867 protein-coding genes and 58 RNAs. Based on phenotypic, biochemical, phylogenetic and genomic evidence, we propose the creation of the new genus Mediterraneibacter and species, Mediterraneibacter massiliensis, that contains strain AT7(T) (=CSUR P2086(T)=DSM 100837(T)), and the reclassification of Ruminococcus faecis, Ruminococcus lactaris, Ruminococcus torques, Ruminococcus gnavus, Clostridium glycyrrhizinilyticum as Mediterraneibacter faecis comb. nov., with type strain Eg2(T) (=KCTC 5757(T)=JCM15917(T)), Mediterraneibacter lactaris comb. nov., with type strain ATCC 29176(T) (=VPI X6-29(T)), Mediterraneibacter torques comb. nov., with type strain ATCC 27756(T) (=VPI B2-51(T)), Mediterraneibacter gnavus comb. nov., with type strain ATCC 29149T (=VPI C7-9T) and Mediterraneibacter glycyrrhizinilyticus comb. nov., with type strain ZM35(T) (=JCM 13368(T)=DSM 17593(T)), respectively.
