Abstract
Clostridium aurantibutyricum
,
Clostridium felsineum
and
Clostridium roseum
share a very high similarity based on multi-locus sequence analysis. In this study, their correct taxonomic status was determined using genomic and phenotypic investigations. Average nucleotide identity based on MUMmer alignment of the genomes and
in silico
DNA–DNA hybridization resulted in values of 98.55–100 and 78.7–100 %, respectively, strongly indicating that all strains are members of the same species. In addition, morphological investigations, fatty acid analyses and substrate utilization tests revealed no striking differences between the strains. Therefore, we propose the reclassification of
C. aurantibutyricum
and
C. roseum
as later heterotypic synonyms of
C. felsineum
. The type strain is lodged in several culture collections (ATCC 17788
T
=DSM 794
T
=NCIMB 10690
T
).
