Abstract

A novel bacterium, designated as strain HJR7, was isolated from a marine sediment sample collected from the coastal area of Weihai, China (121° 57′ E, 37° 29′ N). Cells were Gram-stain-negative, facultative anaerobic, non-motile and rod-shaped. The temperature, pH and NaCl ranges for growth were determined as 4–40 °C, pH 6.5–9.5 and 0.5–15.0 % (w/v), respectively. Phylogenetic analysis based on the 16S rRNA gene sequences indicated that strain HJR7 belongs to the genus in the family . The most closely related species were (97.6 % 16S rRNA gene sequence similarity) and (97.3 % similarity). Ubiquinone 9 (Q-9) was the only respiratory quinone detected in strain HJR7. The major fatty acids of strain HJR7 were C C C N alcohol, Cω and Cω6, 9, 12. The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, and an unidentified phospholipid. The DNA G+C content of strain HJR7 was 53.7 mol%. On the basis of phylogenetic, genotypic, phenotypic, and chemotaxonomic analyses, strain HJR7 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is HJR7 (=KCTC 52545=MCCC 1H00176).
