title: Roseimarinus sediminis gen. nov., sp. nov., a facultatively anaerobic bacterium isolated from coastal sediment.
abstract: A Gram-stain-negative, facultatively anaerobic, non-motile and pink-pigmented bacterium, designated strain HF08(T), was isolated from marine sediment of the coast of Weihai, China. Cells were rod-shaped, and oxidase- and catalase-positive. The isolate grew optimally at 33 °C, at pH 7.5-8.0 and with 2-3% (w/v) NaCl. The dominant cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0 and iso-C14 : 0. Menaquinone 7 (MK-7) was the major respiratory quinone and the DNA G+C content was 44.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolate was a member of the class Bacteroidia, and shared 88-90% sequence similarity with the closest genera Sunxiuqinia, Prolixibacter, Draconibacterium, Mariniphaga and Meniscus. Based on the phylogenetic and phenotypic evidence presented, a novel species in a new genus of the family Prolixibacteraceae is proposed, with the name Roseimarinus sediminis gen. nov., sp. nov. The type strain of Roseimarinus sediminis is HF08(T) ( = KCTC 42261(T) = CICC 10901(T)).
