16S rRNA gene sequence analysis relative to genomovars of Pseudomonas stutzeri and proposal of Pseudomonas balearica sp. nov.
We compared the 16S rRNA gene sequences of 14 strains of Pseudomonas stutzeri, including type strain CCUG 11256 and strain ZoBell (= ATCC 14405), which represented the seven P. stutzeri genomovars (DNA-DNA similarity groups) that have been described. Our sequence analysis revealed clusters which were highly correlated with genomovar clusters derived from DNA-DNA hybridization data. In addition, we identified signature nucleotide positions for each genomovar. We found that the 16S rRNA gene sequences of genomovar 6 strains SP1402T (T = type strain) and LS401 were different enough from the sequence of the type strain of P. stutzeri that these organisms should be placed in a new species, Pseudomonas balearica. The type strain of P. balearica is strain SP1402 (= DSM 6083).
