sp. nov. isolated from ocean sediment Free

Abstract

A Gram-stain-positive, moderately halophilic, motile, strictly aerobic, endospore-forming, rod-shaped bacterium, strain MY11, was isolated from a sediment sample collected from the Western Pacific. This isolate grew in the presence of 0.5–18 % (w/v) NaCl and at pH 6.0–10.0 and 15–45 °C; optimum growth was observed with 3.5 % (w/v) NaCl and at pH 8.0–9.0 and 35–37 °C. Strain MY11 had menaquinone 7 (MK-7) as the predominant respiratory quinone and anteiso-C and anteiso-C as major fatty acids. Major polar lipids were diphosphatidylglycerol and phosphatidylglycerol. The DNA G+C content was 34.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences confirmed that strain MY11 was a member of the genus , exhibiting sequence similarities of 95.3–97.6 % to the type strains of recognized species. Strain MY11 could be differentiated from recognized species of the genus based on phenotypic characteristics, chemotaxonomic differences, phylogenetic analysis and DNA–DNA hybridization data. On the basis of the data presented, strain MY11 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is MY11 ( = LMG 28105 = CGMCC 1.12754 = MCCC 1A09973).
