Abstract

A Gram-negative, facultatively anaerobic, non-motile, rod-shaped and orange-coloured bacterium, designated N62, was isolated from marine sediment of the coast of Weihai, PR China. Strain N62 was found to grow optimally at 28–30 °C, pH 7.0–7.5 and with 2.0–3.0 % (w/v) NaCl. The dominant cellular fatty acids of strain N62 were iso-C, iso-C G, iso-C 3-OH and iso-C 3-OH. The major respiratory quinone was MK-6, and the DNA G+C content was 35.3 mol%. The predominant polar lipids were phosphatidylethanolamine, two unidentified aminolipids, an unidentified glycolipid and three unidentified lipids. Phylogenetic analysis based on 16S rRNA gene sequences revealed that N62 was a member of the family and had a 16S rRNA gene sequence similarity of 95.8–97.2 % with recognized species. On the basis of the phylogenetic and phenotypic evidences, strain N62 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is N62 (=KCTC 42589=MCCC 1H00117).
