- Abstract
- A Gram-negative, strictly aerobic, non-motile, rod-shaped bacterial strain CAU 1614(T) was isolated from a marine sediment sample collected in the Republic of Korea. Optimal growth of strain CAU 1614(T) proceeded at 30 degrees C, pH 7.0, and 2% (w/v) NaCl. 16S rRNA gene similarity was lower than 94.5% with genera Aureisphaera, Marinirhabdus, Aureitalea, Gilvibacter, Ulvibacter, and Jejudonia. The highest similarity was with Aureisphaera galaxeae 04OKA003-7(T) (94.5%). The major cellular fatty acids were iso-C-15:0, iso-C-16:0, iso-C-15:1 G, iso-C-16:0 3-OH, and iso-C-17:0 3-OH and the predominant menaquinone was MK-6. The polar lipids were phosphatidylethanolamine, phosphoglycolipid, an unidentified lipid, two unidentified aminolipids, and an unidentified glycolipid. The draft genome of strain CAU 1614(T) was 3.9 Mb and DNA G+C content was 36.0 mol%. On the basis of the phenotypic, chemotaxonomic, and genomic data, strain CAU 1614(T) presents a novel genus in the family Flavobacteriaceae, for which the name Halomarinibacterium sedimenti gen. nov., sp. nov. is proposed. The type strain is CAU 1614(T) (= KCTC 82457(T) = MCCC 1K06083(T)).
