Chromobacterium alticapitis sp. nov. and Chromobacterium sinusclupearum sp. nov. isolated from wild cranberry bogs in the Cape Cod National Seashore, USA.

Two non-pigmented strains in the genus Chromobacterium, MWU14-2602T and MWU13-2610T, were isolated from wild cranberry bogs in the Cape Cod National Seashore, USA. The isolates were characterized by genomic and phenotypic analyses, the results of which indicated that they represent two novel species. Based on total genome sequences, the closest relatives were in the Chromobacterium amazonense group, which includes the recently described Chromobacterium paludis. Whole genome sequences were compared by genome blast distance phylogeny, digital DNA-DNA hybridization and average nucleotide identity analyses with each other and with the type strains of their nearest species. MWU14-2602T and MWU13-2610T fell well below the accepted cutoff values for species relatedness, clearly indicating that they represent novel species. Although little is known about these organisms in situ, under laboratory conditions, MWU13-2610T produced a modest amount of HCN and was strongly positive for exoprotease activity, whereas MWU14-2602T did not produce HCN or exoproteases. The predominant fatty acids for both isolates were summed C16 : 1ω7cis/C16 : 1ω6cis. Both isolates produced siderophores and pyomelanin pigment on rich media, and neither was haemolytic on sheep blood agar. We propose the names Chromobacterium alticapitis sp. nov. (type strain MWU14-2602T=ATCC TSD 260T=CCOS 1979T) and Chromobacterium sinusclupearum sp. nov. (type strain MWU13-2610T=ATCC TSD-259T=CCOS 1981T) for these taxa.

Chromobacterium pseudoviolaceum Kämpfer et al. 2009 is a later heterotypic synonym of Chromobacterium violaceum Bergonzini 1880.

Published data on the genome sequences of Chromobacterium pseudoviolaceum LMG 3953T and Chromobacterium violaceum ATCC 12472T 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.

Chromobacterium vaccinii sp. nov., isolated from native and cultivated cranberry (Vaccinium macrocarpon Ait.) bogs and irrigation ponds.

A large number of Gram-negative, motile, mesophilic, violacein-producing bacteria were isolated from the soils and roots of Vaccinium macrocarpon Ait. and Kalmia angustifolia L. plants and from irrigation ponds associated with wild and cultivated cranberry bogs in Massachusetts, USA. Phylogenetic analyses of 16S rRNA gene sequences placed these isolates in a clade with Chromobacterium species, but the specialized environment from which they were isolated, their low genomic DNA relatedness with Chromobacterium violaceum ATCC 12472(T) and C. subtsugae PRAA4-1(T), significant differences in fatty acid composition and colony morphology indicate that the cranberry and Kalmia isolates comprise a separate species of Chromobacterium, for which the name Chromobacterium vaccinii sp. nov. is proposed. Strain MWU205(T) ( = ATCC BAA-2314(T)  = DSM 25150(T)) is proposed as the type strain for the novel species. Phenotypic analysis of 26 independent isolates of C. vaccinii sp. nov. indicates that, despite close geographical and biological proximity, there is considerable metabolic diversity among individuals within the population.
