Achromobacter sediminum sp. nov., isolated from deep subseafloor sediment of South Pacific Gyre.
A Gram-stain-negative, facultatively anaerobic, rod-shaped, motile bacterium with a subpolar or lateral flagellum, designated strain XH089(T), was isolated from deep-sea sediment sample collected from the South Pacific Gyre (41°51' S 153°06' W) during the Integrated Ocean Drilling Program (IODP) Expedition 329. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain XH089(T) belonged to the genus Achromobacter and showed the highest 16S rRNA gene sequence similarities with Achromobacter ruhlandii ATCC 15749(T) (96.95%), Achromobacter denitrificans DSM 30026(T) (96.70%) and Achromobacter marplatensis B2(T) (96.66%). The DNA G+C content of strain XH089(T) was 66.5 mol%. The major fatty acids were C16: 0 and C17: 0 cyclo. The major polar lipids were phosphatidylethanolamine, phosphatidylmonomethylethanolamine, diphosphatidylglycerol, three unknown phospholipids and four unknown polar lipids. On the basis of data from the polyphasic analysis, strain XH089(T) is considered to represent a novel species of the genus Achromobacter, for which the name Achromobacter sediminum sp. nov. is proposed. The type strain is XH089(T) ( = DSM 27279(T) = JCM 19223(T)).
