title: Altererythrobacter aurantiacus sp. nov., isolated from deep-sea sediment.
abstract: A Gram-negative, aerobic, coccoid bacterium, strain O30(T), was isolated from a deep-sea sediment sample collected from the west Pacific. 16S rRNA gene sequence analysis revealed that this strain is affiliated with the family Erythrobacteraceae in the class Alphaproteobacteria, and is closely related to the members of the genera Erythromicrobium (96.6 %), Porphyrobacter (95.5-96.3 %), Altererythrobacter (94.1-96.2 %) and Erythrobacter (94.2-96.2 %). Phylogenetic analysis including all described species of the family Erythrobacteraceae revealed that the isolate forms a clade in the cluster of the genus Altererythrobacter. Strain O30(T) was found to grow at 4-40 °C, pH 6.0-10.0 and in the presence of 0.5-7.0 % (w/v) NaCl. Chemotaxonomic analysis revealed ubiquinones Q-8, Q-9 and Q-10 as the predominant respiratory quinones, summed feature 8 (C18:1 ω7c and/or C18:1 ω6c), C17:1 ω6c and C16:0 as major fatty acids, and diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and sphingoglycolipid as the major polar lipids. The DNA G + C content was determined to be 56.9 mol %. On the basis of phenotypic and genotypic data presented in this study, strain O30(T) represents a novel species within the genus Altererythrobacter, for which the name Altererythrobacter aurantiacus sp. nov. is proposed; the type strain is O30(T) (= CGMCC 1.12762(T) = JCM 19853(T) = LMG 28110(T) = MCCC 1A09962(T)).
