An aerobic, Gram-negative, motile, non-pigmented bacterium, strain KMM 3042T, isolated from a deep-sea brittle star in the Fiji Sea, was subjected to a polyphasic taxonomic study. Phylogenetic analysis based on 16S rRNA gene sequences revealed marine Mn(II)-oxidizing isolate S185-2B as the closest neighbour of strain KMM 3042T (99.9 % sequence similarity). The two strains formed a distinct lineage within the genus Pseudomonas adjacent to the members of the Pseudomonas borbori cluster, sharing highest sequence similarity of 97.4 and 97.0 %, respectively, with P. borbori DSM 17834T and Pseudomonas flavescens DSM 12071T. The DNA-DNA hybridization value (71 %) between strains KMM 3042T and S185-2B confirmed their assignment to the same species. On the basis of phylogenetic analysis, DNA-DNA hybridization and physiological and biochemical characterization, strains KMM 3042T and S185-2B should be assigned to a novel species of the genus Pseudomonas, for which the name Pseudomonas marincola sp. nov. is proposed. The type strain is KMM 3042T (=NRIC 0729T =JCM 14761T).
