Pseudoruegeria Aquimaris Gen. Nov., Sp. Nov., Isolated From Seawater of the East Sea in Korea


Pseudoruegeria Aquimaris Gen. Nov., Sp. Nov., Isolated From Seawater of the East Sea in Korea

Jung-Hoon Yoon et al. Int J Syst Evol Microbiol. .


A Gram-negative, non-motile, rod-shaped bacterial strain, SW-255(T), was isolated from seawater from Hwajinpo, on the coast of the East Sea, Korea, and subjected to a polyphasic taxonomic study. Strain SW-255(T) grew optimally at pH 7.0-8.0 and 37 degrees C in the presence of 2 % (w/v) NaCl. It contained Q-10 as the predominant ubiquinone and C(18 : 1)omega7c as the major fatty acid. The DNA G+C content was 67.0 mol%. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain SW-255(T) is phylogenetically closely related to the genera Ruegeria and Silicibacter of the Alphaproteobacteria. The levels of 16S rRNA gene sequence similarity between strain SW-255(T) and the type strains of Ruegeria atlantica and two Silicibacter species were in the range 95.8-96.2 %. A phylogenetic tree based on gyrB sequences showed that strain SW-255(T) forms a distinct evolutionary lineage within the Alphaproteobacteria. Differential phenotypic properties, polar lipid profiles and DNA G+C contents, together with the phylogenetic distinctiveness, suggest that strain SW-255(T) should be distinguished from the members of the genera Ruegeria and Silicibacter. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain SW-255(T) represents a novel genus and species, for which the name Pseudoruegeria aquimaris gen. nov., sp. nov. is proposed. The type strain of Pseudoruegeria aquimaris is SW-255(T) (=KCTC 12737(T)=JCM 13603(T)).
