Abstract

Published data on the genome sequences of Chromobacterium pseudoviolaceum LMG 3953 and Chromobacterium violaceum ATCC 12472 suggest that both isolates belong to the same species. Previous 16S rRNA gene sequence comparisons had demonstrated that these species share 99.9 % sequence similarity. Initial investigations of fatty acid patterns and substrate utilization had shown only a few differences between the type strains of both species. Despite the 47.5 % homology by DNA–DNA hybridization studies between these strains, in silico whole genome sequence comparisons have clearly demonstrated that OrthoANIu and Mash/MinHash values were >99.18 %. Molecular phylogeny based on the estimated phylogenetic positions of the published genome sequences of the two type strains, and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analyses indicate that these strains are members of the same species. Due to priority of publication and validation of names, Chromobacterium pseudoviolaceum is reclassified as Chromobacterium violaceum .
