Numerical analysis of phenotypic data revealed two phena, A (including the P. corrugata type strain) and B, which could be clearly differentiated by the assimilation of mesotartrate, 2-ketogluconate and histamine. The mean DNA reassociation values with labelled DNA of P. corrugata type strain CFBP 2431T (phenon A) and strain CFBP 5447T (phenon B) were high for strains belonging to the same phenon (96.9 and 98.5%, respectively), whereas the DNA relatedness between the two phena was assessed as being close to 70%, which represents the value that is accepted for the definition of a bacterial species. Phena A and B were also differentiated by means of DNA profiles generated by heteroduplex mobility assay of PCR products of 16S rDNA hypervariable region 2, HaeIII restriction of the amplified internal transcribed spacer, REP- and BOX-PCR profiles, and by PCR with two pairs of specific primers. A comparison of the 16S rRNA sequences of strains CFBP 5447T and CFBP 5458 from phenon B with the available sequences of Pseudomonas species showed that these strains formed a cluster distinct from the P. corrugata type strain. Thus, a new species, Pseudomonas mediterranea, is proposed for strains of phenon B. The type strain is strain CFBP 5447T (= ICMP 14184T); its G+C content is 60.2 mol%. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-52-5-1749
