title: Salinovum rubellum gen. nov., sp. nov., isolated from sediment of a saltern.
abstract: An aerobic, Gram-reaction-negative, oxidase-positive and catalase-positive strain, YCWB25T, was isolated from saltern farm sediment in Jimo-Daqiao of Qingdao, east coast of China. This strain had an absolute requirement for NaCl and was able to grow in the presence of 1-10 % (w/v) NaCl (optimal growth at 3-5 % NaCl). The strain grew at pH 5.0-9.0 (optimal growth at pH 8.0) and 4-42 °C (optimal growth at 30 °C). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain YCWB25T belonged to the Roseobacter clade of the family Rhodobacteraceae, and the closest species were members of the genus Pseudooceanicola (similarity lower than 95.58 %). However, the novel strain formed a robust, distinct clade different from other members of the Roseobacter clade. The DNA G+C content of strain YCWB25T was 65.6 mol%. The predominant respiratory quinone was Q-10. The dominant cellular fatty acids were C18 : 1ω7c, C16 : 0 and C19 : 0 cyclo ω8c. The phenotypic, chemotaxonomic and phylogenetic data indicated that strain YCWB25T represents a novel species of a new genus, for which the name Salinovum rubellum gen. nov., sp. nov. is proposed. The type strain of Salinovum rubellum is YCWB25T (=MCCC 1K00272T=LMG 25394T).
