Sarrella massiliensis gen. nov. sp. nov., a new gut genus isolated from the stool of a healthy donor
Strain Marseille-QA0792 (=CSUR QA0792, CECT 31199) was isolated from the feces of a healthy person using the culturomics method. The fecal sample originated from leftover material collected for a fecal microbiota transplantation (FMT) procedure, obtained during a routine screening in accordance with the guidelines of the French National Agency for Medicines and Health Products Safety (ANSM).

A novel gut genus, Sarrella massiliensis gen. nov., sp. nov., has been isolated from the stool of a healthy donor through the culturomics method. The strain, identified as Gram-stain-negative, rod-shaped, non-motile, and non-spore-forming, thrives optimally at 37°C in an anaerobic environment. The strain shows a high 16S rRNA sequence identity (96.2%) with Merdibacter massiliensis strain Marseille-P3254, though it lacks a valid publication.
Additionally, it shares a notable 75.0% average nucleotide identity (ANI) with the same species. In comparison to validly published species, it demonstrates a 91.5% 16S rRNA sequence similarity to Faecalicoccus acidiformans strain 37-2a, although no ANI values exceed 75%. Genome sequencing confirms a genome size of 2.67 Mb and a G+C content of 50.01%.
Classified within the Erysipelotrichaceae family of the Bacillota phylum, this marks the first time a new genus, Sarrella massiliensis gen. nov., has been identified. This discovery underscores the significance of ongoing culturomics efforts to delve deeper into the human microbiome.
