Haloferula chungangensis sp nov., isolated from marine sediment

초록

A Gram-stain-negative, non-spore-forming, non-motile, strictly aerobic, rod-shaped bacterial strain, designated CAU 1074(T), was isolated from marine sediment and its taxonomic position was investigated using a polyphasic approach. Strain CAU 1074(T) grew optimally at 30 degrees C and pH 6.5. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CAU 1074(T) formed a distinct lineage within the genus Haloferula and was most closely related to Haloferula harenae KCTC 22198(T) (96.0% similarity). Strain CAU 1074(T) contained MK-9 as the major isoprenoid quinone, and iso-C-14:0, C-16:1 omega 9c and C-16:0 as the major fatty acids. The cell wall peptidoglycan contained meso-diaminopimelic acid. The major whole-cell sugars were glucose, xylose, mannose and ribose. The polar lipids were composed of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, aminoglycolipid and two unidentified phospholipids. The DNA G+C content of the strain was 64.0 mol%. On the basis of phenotypic and chemotaxonomic data, and phylogenetic inference, strain CAU 1074(T) should be classified as a member of a novel species in the genus Haloferula, for which the name Haloferula chungangensis sp. nov. is proposed; the type strain is CAU 1074(T) (=KCTC 23578(T)=CCUG 61920(T)). An emended description of the genus Haloferule is also provided.
