Genome-Based Species Diversity Assessment in the Pseudomonas chlororaphis Phylogenetic Subgroup and Proposal of Pseudomonas danubii sp. nov. Isolated from Freshwaters, Soil, and Rhizosphere

The Pseudomonas chlororaphis phylogenetic subgroup of species, within the fluorescens group, currently includes seven bacterial all which have environmental relevance. Phylogenomic analyses help clarify taxonomy strains in group and allow for precise identification. Thirteen antibiotic-resistant isolated a previous study from nine different sampling sites Danube River were suspected to represent novel species are investigated taxonomically present study, together with four other Woluwe (Belgium) that phylogenetically closely related their rpoD gene sequences. characterized phenotypically, chemotaxonomically (fatty acid composition main protein profiles), phylogenetically. They could not be assigned any known species. Three genomes representative sequenced analyzed context genome sequences available public databases. phylogenomic analysis demonstrates need differentiate new genomic P. piscis aestus synonyms.
