Abstract
Strain TB1-E2-13T was isolated from water collected from the Tidal Basin in Washington, D.C., USA, due to the bright purple colour of its colonies, and was taxonomically evaluated with a polyphasic approach. Comparison of a partial 16S rRNA gene sequence found that strain TB1-E2-13T was most similar to species in the Janthinobacterium genus. For more precise taxonomic inference, a phylogenomic analysis was conducted and indicated that strain TB1-E2-13T was most closely related to Janthinobacterium lividum, 'Janthinobacterium kumbetense', Janthinobacterium rivuli and Janthinobacterium violaceinigrum. Analyses of genomic indices found that pairwise comparisons between strain TB1-E2-13T and other members of the Janthinobacterium genus returned values below the threshold of species novelty. Based on a polyphasic characterization and identifying differences in genomic and taxonomic data, strain TB1-E2-13T represents a novel species, for which the name Janthinobacterium aestuarii sp. nov. is proposed. The type strain is TB1-E2-13T (=ATCC TSD-339T=JCM 36076T).
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.
