title: Eubacterium minutum is an earlier synonym of Eubacterium tardum and has priority.
abstract: The recently proposed species Eubacterium minutum and Eubacterium tardum appeared to be similar from their published descriptions. The aim of this study was to perform phenotypic and genetic analyses of strains of both species to clarify their taxonomic position. The type strains of E. minutum and E. tardum exhibited identical biochemical and protein profiles and their 16S rRNA gene sequences displayed 99.9% similarity. The G + C content of the DNA of both strains was estimated at 45 mol%. It is concluded that E. minutum and E. tardum are synonyms; E. minutum has priority. An emended description of E. minutum is given.
