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).

从美国华盛顿潮汐盆地分离出的一种新的产紫罗兰素的细菌。
菌株TB1-E2-13T因其菌落呈亮紫色而从美国华盛顿潮汐盆地收集的水中分离得到,并采用多相法进行了分类评价。比较部分16S rRNA基因序列发现菌株TB1-E2-13T与Janthinobacterium属的物种最为相似。为了进行更精确的分类推断,进行了系统基因组分析,结果表明菌株TB1-E2-13T与lividum Janthinobacterium kumbetense、Janthinobacterium rivuli和Janthinobacterium violaceinigrum亲缘关系最密切。基因组指数分析发现,菌株TB1-E2-13T与Janthinobacterium属其他成员的两两比较返回值低于物种新颖性阈值。基于多相鉴定和基因组和分类学数据的差异,菌株TB1-E2-13T代表了一个新物种,建议将其命名为Janthinobacterium aestuarii sp. 11。型应变为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.
