Pseudomonas izuensis sp. nov., a novel species isolated from Izu Oshima, Japan.

ABSTRACT

An aerobic, Gram-stain-negative, rod-shaped bacterial strain, IzPS43_3003T, was isolated from Izu Oshima, an active volcanic island located 22 km east of the Izu Peninsula, Japan. The sequence of its 16S rRNA gene indicated that IzPS43_3003T belongs to the Pseudomonas fluorescens lineage, with its sequence being most similar to that of Pseudomonas vancouverensis DhA-51T (99.79 %). Phylogenetic analysis based on whole genome sequences showed that IzPS43_3003T was a member of the Pseudomonas jessenii subgroup. The average nucleotide identity values and genome-to genome distances between the whole genome sequences of IzPS43_3003T and other type strains showed that the highest correlations were with Pseudomonas moorei DSM 12647T (87.3 and 33.5% respectively). These genotypic and phenotypic analyses indicated that IzPS43_3003T belongs to a novel species, Pseudomonas izuensis sp. nov. Its type strain is IzPS43_3003T (=LMG 31527T,=CECT 9963T).
