title: Phaeobacter daeponensis sp. nov., isolated from a tidal flat of the Yellow Sea in Korea.
abstract: A Gram-negative, motile and egg-shaped bacterium, strain TF-218(T), was isolated from a tidal flat at Daepo Beach (Yellow Sea), Korea, and subjected to a polyphasic taxonomic analysis. Strain TF-218(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 and 11-methyl C(18 : 1)omega7c as the major fatty acids. The major polar lipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, two unidentified lipids and an aminolipid. The DNA G+C content was 64.9 mol%. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain TF-218(T) is phylogenetically closely related to the genera Phaeobacter, Leisingera and Marinovum of the Alphaproteobacteria. The phylogenetic and chemotaxonomic similarities suggest that strain TF-218(T) represents a member of the genus Phaeobacter. DNA-DNA relatedness data and differential phenotypic properties, together with the phylogenetic distinctiveness, demonstrated that strain TF-218(T) differs from the recognized Phaeobacter species. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain TF-218(T) represents a novel species of the genus Phaeobacter, for which the name Phaeobacter daeponensis sp. nov. is proposed. The type strain is TF-218(T) (=KCTC 12794(T)=JCM 13606(T)).
