Abstract A novel aerobic, Gram-stain-negative bacterium, designated strain 2ED5T, was isolated from a deep seawater sample in the north-west Indian Ocean. Cells of the strain were oval- to rod-shaped, and motile by a polar flagellum or sessile by a prostheca. The strain formed creamy white colonies on 2216E marine agar plates. It grew at 10-40 °C (optimum 28 °C) and pH 5.0-8.0 (optimum pH 6.0-7.0). The strain required 1-6 % (w/v) NaCl for growth and grew optimally in the presence of 2-3 % NaCl. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain 2ED5T was affiliated with the genus Hyphobacterium in the family Hyphomonadaceae of the class Alphaproteobacteria, sharing 95.1 % similarity at the 16S rRNA gene sequence level with the type strain of Hyphobacterium vulgare, the only species in the genus Hyphobacterium. The major fatty acids of the strain were C18 : 1ω7c and iso-C17 : 1ω9c, and the polar lipids included monoglycosyl diglyceride, sulfoquinovosyl diacylglycerol, glucuronopyranosyl diglyceride, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and an unidentified glycolipid. The strain contained ubiquinone Q-10 as the predominant respiratory quinone. The G+C content of the genomic DNA of the strain was 60.9 mol%. Based on the results of this polyphasic analysis, strain 2ED5T represents a novel species in the genus Hyphobacterium, for which the name Hyphobacterium indicum sp. nov. is proposed. The type strain is 2ED5T (=CGMCC 1.16466T=JCM 32612T).
