Abstract

A Gram-stain-negative, aerobic, non-gliding, rod-shaped and orange-coloured bacterium, designated strain P131, was isolated from marine sediment of the coast of Weihai, China, and subjected to a polyphasic study. Strain P131 was found to grow optimally at 28–30 °C, at pH 7.0–7.5 and in the presence of 2–3 % (w/v) NaCl. In a phylogenetic analysis based on 16S rRNA gene sequences, strain P131 was found to belong to the genus and exhibited 94.6–97.0 % 16S rRNA gene sequence similarity with recognized species. The dominant cellular fatty acids of strain P131 were identified as iso-C, iso-C G, iso-C 3-OH and iso-Cω9. The predominant polar lipids were phosphatidylethanolamine, phospholipid, two aminolipids and two unidentified lipids. The predominant respiratory quinone was menaquinone MK-6 and the DNA G+C content was 36.7 mol%. On the basis of the phylogenetic and phenotypic evidence presented, strain P131 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is P131 (=KCTC 42587=MCCC 1H00124).
