Abstract:
A slightly halophilic, Gram-negative, strictly aerobic, non-motile rod, designated TW15 T , was isolated from an ark clam in South Korea. Growth occurred at 10–37 °C, with 1–5 % (w/v) NaCl and at pH 7.0–10.0. Optimal growth occurred at 25–30 °C, with 2 % (w/v) NaCl and at pH 8.0. Strain TW15 T exhibited both oxidase and catalase activities. The major fatty acids of strain TW15 T were summed feature 8 (consisting of C 18 : 1 ω7 c and/or C 18 : 1 ω6 c ) and 11-methyl C 18 : 1 ω7 c . The predominant isoprenoid quinone was ubiquinone-10 (Q-10). The polar lipids of strain TW15 T comprised phosphatidylcholine, phosphatidylglycerol, diphosphatidylglycerol, an unidentified phospholipid, an unidentified aminolipid and five unidentified lipids. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain TW15 T was most closely related to Ruegeria lacuscaerulensis DSM 11314 T (98.0 % 16S rRNA gene sequence similarity). DNA–DNA relatedness with closely related strains was 〈 52±3 %. The DNA G+C content was 55.7 mol%. On the basis of phenotypic, genotypic and phylogenetic data, strain TW15 T represents a novel species of the genus Ruegeria , for which the name Ruegeria conchae sp. nov. is proposed. The type strain is TW15 T ( = KACC 15115 T = JCM 17315 T ).
