Reclassification of Butyrivibrio crossotus Moore et al. 1976 (Approved Lists 1980) into a novel genus as Eshraghiella crossota gen. nov., comb. nov.
The reclassification of Butyrivibrio crossotus Moore et al. 1976 (Approved Lists 1980) as Eshraghiella crossota gen. nov., comb. nov. is proposed within the family Lachnospiraceae. This reclassification is based on differences revealed through the analysis of 16S rRNA, groEL, recA, and rpoB genes, as well as genome sequences, distinguishing it from other Butyrivibrio species. Comparative analysis showed that B. crossotus exhibited digital DNA-DNA hybridization (dDDH) values of 19.40-27.20% and average nucleotide identities based on blast (ANIb) values of 67.06-67.64% with other Butyrivibrio species. These values are significantly below the species delineation thresholds (dDDH, 70%; ANIb, 95-96%), justifying the proposed reclassification. Additionally, the results of the average amino acid identity (AAI) analysis indicated that this species shares 59.22-60.17% AAI with the other species of the genus Butyrivibrio, which is below the AAI threshold (65%) for a genus boundary. In addition, biochemical and morphological characteristics also support the proposal that this species is different from other species of the genus Butyrivibrio. The type strain is ATCC 29175T (DSM 2876T=T9-40AT).
期刊介绍：
Published by the Microbiology Society and owned by the International Committee on Systematics of Prokaryotes (ICSP), a committee of the Bacteriology and Applied Microbiology Division of the International Union of Microbiological Societies, International Journal of Systematic and Evolutionary Microbiology is the leading forum for the publication of novel microbial taxa and the ICSP’s official journal of record for prokaryotic names.
The journal welcomes high-quality research on all aspects of microbial evolution, phylogenetics and systematics, encouraging submissions on all prokaryotes, yeasts, microfungi, protozoa and microalgae across the full breadth of systematics including:
Identification, characterisation and culture preservation
Microbial evolution and biodiversity
Molecular environmental work with strong taxonomic or evolutionary content
Nomenclature
Taxonomy and phylogenetics.
