Abstract

An anaerobic bacterium, strain AT2, was isolated from the fresh stool sample of a healthy French man using the culturomics approach. The 16S rRNA gene sequence analysis showed that strain AT2 had 95.2 % nucleotide sequence similarity with ATCC 27749, the phylogenetically closest species with standing in nomenclature. Cells are Gram-stain-negative, catalase- and oxidase-negative, obligately anaerobic, non-motile, non-spore-forming, rod-shaped, and the bacilli were mesothermophilic. The major fatty acids were C (43.8 %) and C (20 %). The DNA G+C content of the strain based on its genome sequence was 56.8 mol%. Based on the phenotypic, biochemical and phylogenetic analysis, we propose the creation of the genus gen. nov., which contains strain AT2 (=CSUR P2014=DSM 100451) as the type strain of the type species gen. nov., sp. nov.
